Rear Suspension Support

Towing or hauling a heavy load can cause rear sag as your factory suspension compresses under the weight of the load. This means that the rear axle is trying to support not only the extra load but also the weight of your vehicle. And because there is less weight on your front axle, your front tires make less contact with the road, which causes problems with traction, steering, and braking. SumoSprings upgrade your vehicle's factory suspension to level your vehicle, improve driving performance, and keep your ride comfortable.


Installed spring when it is not compressed

SumoSprings provide progressive load control - the more you load them, the stiffer they become. With a lighter load, the springs will compress easily for soft engagement and a less bumpy ride. The closed-cell urethane material allows for smooth contact between the springs and your vehicle. And the springs act like a shock absorber to dampen road vibration.


Installed spring when it is compressed

The springs can also compress by as much as 80 percent to support a heavy rear load and to help your factory suspension bear up under the load. This evens out the weight, which levels your vehicle and ensures that your front tires are making better contact with the road. A level ride means that you have improved driving control, ensures safe headlight aim, and helps to minimize sway. The springs also support your factory suspension, which helps prevent sagging and reduces bottoming out.


The springs work independently from one another to support each side of your vehicle. This action helps to reduce body roll when you make a sharp turn. This also helps compensate for an off-center load.


Durable, Custom-Fit Springs

These microcellular urethane springs are tough. They resist abrasion, oil, salt, and UV rays that can more quickly wear out other springs, and they perform well in temperatures ranging from -25 F to 200 F (-33 C to 93 C).


SumoSprings compress vertically with minimum expansion to the sides, so they won't be damaged by nearby mechanical parts and they fit safely into tighter spots. And unlike air springs, SumoSprings require no maintenance or adjustment.


The helper springs are custom designed to fit your vehicle, and they install easily - no drilling required.

Video Transcript for SumoSprings Solo Custom Helper Springs Review

Speaker 1: Today, we'll be taking a look at the SumoSprings Solo Line of Custom Helper Springs for the rear axle. You'll want to use eTrailer's fit guide to determine the correct kit for your vehicle. This is what our SumoSprings look like when installed. Yours may look a little different depending on your vehicle.They're gonna replace our factory jounce stops and sit right between our frame and our rear axle. So whenever we're carrying a heavy load, they're gonna give us that extra support that we need. The way our SumoSprings are gonna work is when our suspension starts to sag from the heavy load, these are gonna absorb a lot of that weight.They are gonna work independently from each other so it's gonna help with those off-center loads.

Our springs are gonna have a progressive rate to 'em. So if we have a light load, they're gonna compress softly, still giving us that comfortable ride. But the heavier load we put on 'em, the more they're gonna compress and the more firmness they're gonna have to them.Now comparing to our factory jounce stop, you can see there's a big difference in height. These are gonna give us a lot more compression, whereas our factory jounce stops are really just preventing the axle from hitting the frame.We have a water tank at the bed of our truck as a heavy load or to simulate the tongue weight of a heavy trailer or a fifth wheel. So as I take the truck through my test course, I can definitely tell that there's a load back there.

The engine doesn't seem to be strained that much, but the bumps are extremely harsh and I can definitely feel it resonating through the seat.When I come to the slalom course and I'm going through the turns, it definitely has a lot of body roll and I just generally feel like I need to slow down because it feels likes it's leaning a lot and it's not responding quickly enough to the turns.Now that we have our SumoSprings installed and I have the same load back there, when I'm driving through our course, I can immediately tell a difference. It's much of a smoother ride. Going over the bumps really doesn't feel like anything's back there and it's just a lot more comfortable.When I come into the slalom course, it definitely feels a lot more stable and it doesn't seem to sway as much side to side and it just generally feels like it wants to go faster.These are made of a durable micro cellular urethane that works in temperatures from -25 degrees to 200 degrees Fahrenheit, and resists damage caused by oils, road salts and UV rays. Compared to air bags, these are maintenance free option with no tubes to run or air pressure to maintain. Both will help level your load and provide a smoother ride.

Airbags can be adjusted to suit your needs whereas the SumoSprings are a fixed option.That completes our look at the SumoSprings Solo Line of Custom Helper Springs for the rear axle.

Product was delivered and was a breeze to install! A friend happened to be around when I got started and we had them both installed in less than 20 minutes with the help of a car lift available to us. Didn't quite raise the bed of the truck as far as I hoped it would, but still a great product! Guess that's just the Baja Edition? But did find out I might need different shocks so that will be my next step soon. 508762

Great product ! Does all it claims and more than i expected. I leave my 5th wheel hitch mounted yr. round and haul bins of sand when I plow in the winter, so it's helping all the time. I can see and feel a difference in hauling our 30 ftr. Doesn't change the ride at all like just about anything else you'd need to do to get the help these give you. Easy install too! 347625

Still goin strong. I’ve had numerous campers even a Tundra owner inquire about what I’ve done to level my truck for the load. It totally out does more springs! When and if they fatigue, I’ll buy em again.

Re levels the poor Tacoma leaf springs. But definitely stiffens the ride on the off-road Bilstein shocks. If you carry a reasonable amount of weighted recovery gear at all times like I do, these are worth adding to your suspension. I installed them in 20 minutes. 561552

Definitely recommend these helper springs. Have a 2008 Toyota Tacoma and they have a recall on the rear springs. Waiting on appointment now. The truck always had light rear springs. Could feel the springs hitting the stops with just hitting a small bump. I also tow a travel trailer so I needed help. I installed air-lift bags and after 2 bag leaks I had enough. Shop Etrailer where I buy all my towing needs. Bought sumo springs and what a difference with handling and towing. No body roll and no spring bumps. Worth every penny and no worries. Buy sumo and buy them from Etrailer. 278041

Truck type: 2008 Toyota Tacoma SR5 Prerunner 2 WD Installation: Easier than an oil change. Took me about 8 minutes per part. I lifted the truck's receiver hitch 3 or 4 cm before starting. 19mm deep socket was the only tool needed. Did not even remove the U-bolts, simply loosened, removed old OE rubber pyramid bump part, and replaced with the SumoSpring parts. Results: fender height was normally 36.5". With RV on at 400 pounds hitch weight, compression was 4" before SumoSpring. After install, compression is 1.5". Leveling problem solved. As for ride without RV, I found an old bumpy concrete street nearby, ride quieter and smoother. On corners, truck is more stable and does not rock as much due to "centrifugal force". Overall: I like what I'm seeing. Will write again once I road trip the RV. 574225

2013 Toyota Tundra

Installed the SumoSprings foam helpers on rear of 2013 Tundra to smooth out the bumps in the interstates when pulling our 7600 lb travel trailer. Transaction and shipping from E-trailer was seamless as always. Installation took maybe 30 minutes and I didn't even remove the wheels. Unloaded and solo, there is maybe 1/8" clearance between the frame and the top of the pads so they engage very quickly when load is added. When I add my 950 lbs of tongue weight, the rear sag of the truck is reduced from 3.5 inches to 2.75 inches. This reduced sag required a re-adjustment of my Equal-izer WD hitch which was by far the most time consuming work. With adjustments made, the ride is noticeably better on the interstate. The loaded ride is a little more firm but the hard bounces generated from my frame hitting the stock spring jounces is eliminated. Unloaded I can't really tell any difference in ride. I researched air bags and the other non-air-bag spring helpers, but I believe this product was the best addition for the Tundra. Tundra's do not have a lot of cargo capacity anyway, and Sumo told me they design this particular product for the Tundra specifically to create a balance between reasonable cargo loading and stiffness/ride quality. They said that is why this product looks different for different applications - they design each piece for the specific truck and load/spring characteristics. 154660

Purchased for a Tacoma 4 dr, long bed, with a fiberglass cap. I have the TSB/recall replacement spring pack. With this set up I had a decent ride, and better support over the OEM springs, but still see that the springs provided only minimal improvement when loading in the bed say 300-500#. If so loaded (camp gear, MC gear, 2-3 persons in cab) on moderate unpaved roads the OEM springs were at max load and had we too much frame sag. WITH the addition of the SumoSpring kit I found my truck when UNLOADED handled the same, but did have less body roll in the rear. At rest the frame rail is just touching the SumoSpring and wheel well to ground is 36 1/2" with P245 tires. When LOADED as detailed above, the rear feels firmer, has less body roll, and does not sag to excess like the OEM spring pack. Very satisfied with results. A very nice enhancement at a excellent price point. Kit is simple to install and should require no regular service/adjustment. 353831

My Sumo Springs Supersprings are working out Great on my 2016 Tacoma. At first they felt a little stiff, but I soon got used to the way the truck rides and I'm very happy. Last Spring I needed to get some paving bricks for a small project in the garden and I found an ad for "About 100 Bricks" on Craigslist not too far from home. By the time I got the load of bricks in the truck, the actual number was closer to 300. Boy, was I glad that I had the Sumo Springs installed on the truck! I did take it easy on the ride home, but the Supersprings did the trick. I regularly use my truck to carry equipment for my small business and while it not as heavy as 300 bricks, my truck rides nice a level and I don't bottom out when there's a pot hole or a bump in the road. My thanks to Sumo Springs and Etrailer. 343816

Beginning in April 2015, I have loaded my 2014 Toyota Tacoma PreRunner pretty heavily every year and make the trip back in forth between Houston and Austin in support of the MS150 bicycle ride. Last year I could tell just how loaded my truck really was and it felt unstable. It was after that, that I installed the SumoSprings. This year my truck was just as loaded but the ride was much more stable and there was very little sag in the suspension. I'm sold. 375227

Overall the product was very good and easy to install. I used red Loctite on all the hardware components and I have not had any issues. I will say the product helps to reduce sagging with heavier loads in the bed of the truck. The springs did increase the rear ride height to that of slightly higher than the front end. When the truck is unloaded the ride of the truck is a little more stiff than I prefer. I would buy this product again. 524478

Toyota Tacoma 2011 4 door short box Sport Great product. Other reviews said that it was easy to install Ya right, It was easy to install to much of my dismay. When it is installed it said that you have some space between the leaf spring and the sumo spring I did not, it is in contact with the leaf spring on my truck at all times. The ride is a bit stiffer when empty but it gives the truck a little rake that I like. Now when I have about 700-1000 in the back I have no problem with sag and the truck rides smooth. If this Tacoma ever wears out I will put one of these on my next Tacoma. 635661

Great service and prompt delivery from etrailer. I haul a small backhoe on a trailer with my Nissan Titan. The SumoSprings solve the small amount of rear sag I experience when hauling but do not affect ride during everyday driving. The product is great and I would recommend them to anyone experiencing similar issues. My first purchase from etrailer has exceeded my expectations. I would recommend them as well. 604797

So far, so good. Installation on my 2014 Tacoma went very well. The truck now sits about 3/4" higher in back and feels a little firmer in the ride. I plan to hook up my RV trailer this week. It looks like these will work just fine to eliminate the "tail sag" that so many Tacoma owners report. 526827

Awesome product. They have taken some strain off the leaf springs during long heavy drives. Biggest difference has definitely been the added stability on the freeway. It has also helped minimize body roll when cornering at speed. Might have to invest in pair for the front of the truck! 479254

I put these on a 2016 Tacoma Off Road that tows a 4000 lb travel trailer. They have little or no effect on the truck when empty, but limit the suspension travel with the 450 lb tongue weight of the trailer. I far prefer them to air bags, which ave always eventually leaked down. 439574

Level the ride under load. They have worked great under various circumstances. Wether the bed is full of yard waste, pulling a lightweight trailer and a heavier travel trailer, truck has the same nice ride. 369958

Product arrived in great shape and packed well from etrailer.com. Installation was simple and went smoothly. Real test will be a couple of weeks out when I tow the camper and truck out to Big Bend fully loaded. Even unloaded, the truck felt a little less bouncy, they dampened the suspension a bit. I'm looking forward to a full test in a few weeks. 337400

I put these on my 2007 Tundra to help it handle the heavy loads and 8,000 lb trailer that I tow. I am completely satisfied. They don't make the ride harsh when empty but they certainly add extra load carrying capacity when needed. They seem to be holding up fine. I expect they will last for years. 289267

My order arrived 4 days early, WOW. I did use 2 flat blade screw drivers to remove the old bumpers. When I installed the new Sumo Springs I put a little liquid soap on the top edges, this helped pop them in. I also used a piece of 2X4 to help push them in, and quickly released the floor jack and this seated them in fully. Quick install took about 20 min. I have less than 1" at the bottom. Unloaded ride is same as before. With my trailer attached (1200 LBS hitch weight) the short test drive I felt much better control and less bounce. Very happy with product and etrailer.

Without a doubt - excellent product. With research you will find that the Ford E450 rubber bump stops are installed using metric while the Sumo product goes on with standard. The passenger side rear had a bracket attached holding brake lines so using a washer was out of the question. Overall they went on easily and when tested made turning so much more comfortable. Top used to sway so much, now WOW! I should have done this when I first bought the rig. Thanks Sumo and etrailer! 605554

Put these in my 2007 Tundra. I could tell a great difference just rounding corners with stability with out a trailer on. I like my trucks to ride like trucks and this for sure helped with that.

I put these on my 2017 2 door jeep wranger. I have factory springs no lift. I put on aftermarket front bumper with wench, rear bumper, roof rack. With all the other gear in the jeep, frig, and all camping gear, and plans on putting on a rooftop tent. The ride was a harsh because off all the extra weight, so i thought i would give it a try. I first got air bags for the rear and they worked great, improving the ride, but now the front was still harsh. So i thought i would try the sumosprings. All i can say about the sumosprings is that there awesome. I can now go over bumps on dirt roads, paved roads, train tracks, and it dosnt beat the crap out of me. Jeep feels like its happy. 518093

It was interesting to note the height of the OEM versus these springs - these are much longer. I installed these front springs and the rear springs together and they significantly reduced the roll in my class B rv. I was able to install these myself and, at least for me, it was a lot easier using a second person to hold the spring in place below while I installed the retaining nut above. I used the appropriate jack and jack stands. 591696

100% stock 2017 Tundra SR 4WD V8. Bought these to provide a bit more stability when towing 27' 8600 GVW tag along camper usually running around 8000lb actual weight. Weight distributing hitch w/ sway control. Wasn't horrible before but wanted suspension stiffened up some. Easy to install if you have a torque wrench and the most basic of hand tools. Did exactly what I wanted it to do. 467194

2011, F53, 22,000 lbs chassis. After having adjusted tire pressure, installing new shocks and a rear trac bar, these are the icing on the cake. I installed the front Sumo’s and was so impressed I immediately purchased the rears. The side-to-side sway is almost completely gone, my motorhome tracks so much better now, and it actually soaks up a lot more of the little bumps. I’m really happy with the Sumo Springs and Etrailer. 225878

Great service arrived in 3 days. Installed the Sumo springs last weekend. It was about a 15 minute job on a P32 chassis. I used the supplied spacers and it raised the rear end about 1/2 inch and really reduced the body roll. They replaced the stock rear jounce bumpers which were shot. This is what should have come on the motorhome from the factory. 151532

Installed the black sumo only 2 wekks ago.Should have done that right after reception last year. Reduce sway totally when i leave my yard(3 inches bump). Don,t need stabilizator,floor is very solid and stable. On the road test for only 10 miles, there is a much better stability. I already have yellow sumo on front suspension where suspension was weak and direction instable.those problems have disapeared. Very satisfied client. 07 view sprinter 2006 579304

Review from a similar SuperSprings SumoSprings Solo in Vehicle Suspension


Product came in just fine and right on time. Installation was as simple as could be. Couldn't accurately give a review on their performance as this was for a customer's vehicle and we aren't using them. All the ones that we have used have worked remarkably well, however. 397591

Review from a similar SuperSprings SumoSprings Solo in Vehicle Suspension


Install was super easy and the product does what it claims to do. Hauling the horse trailer with these added on is much more stable (no pun intended) and the sway is almost eliminated. 545406

Review from a similar SuperSprings SumoSprings Solo in Vehicle Suspension


The product was easy to install. The Tools needed list needs to be updated. Removing bolt is 13mm. Installing new bolts are 15mm. Also the nuts that are tack welded inside the frame will break loose if any rust or debris are on the threads. Back up wrench is near impossible if to fit if the size is not known. End up cutting the old bolt because of this. That’s not your products fault. That’s Fords issue. With the 1” spacers provided it raise my F150 4 1/2”. Stiffened the ride up. Ready to haul my 5th wheel. NICE 452641

The Sumo Springs are still performing well. I Hauled our 29.5 5th Wheel from Upstate NY TO Florida through a major 4 State nor’easter. We have also bought a 16’ cargo trailer and hauled it to it’s full weight capacitie. The truck is still sitting high.

  • How to Pick Out SumoSprings Suspension Enhancement for 2016 Ford F-250
  • For your 2016 Ford F-250 Super Duty there are two SumoSprings options that fit your truck like you mentioned. There's the 2,800 lb kit part # SSR-114-54 and the 1,500 lb kit part # SSR-114-47. Basically you want to go with the lightest duty kit that will work for your application. Going heavier than you need will give you a harsher ride quality than you'll want loaded and unloaded. You didn't mention the pin or tongue weight of your trailer, but unless you are at the max capacity for...

  • Recommended SumoSprings System for 2012 Toyota Tacoma Pre-Runner SR5
  • I do have a solution for you, however the SumoSprings Solo Custom Helper Springs # SSR-611-40 referenced in your question is not designed to fit your Pre-Runner model of the 2012 Toyota Tacoma. For your Tacoma Pre-Runner, I instead recommend the SumoSprings # SSR-610-40. These urethane springs are confirmed to fit your truck and will do a great job of upgrading the rear suspension for improved control and comfort. Its 1,000 pound capacity will keep your truck level when hauling a heavy...

  • Recommended SumoSprings For Rear Axle Of A 2017 Toyota Tacoma SR5 4x4
  • The SumoSprings Solo Custom Helper Springs - Rear Axle, # SSR-610-40, are great jounce springs with a capacity of 1000 lbs at 50% compression. The # SSR-610-47 that you are referring to is a heavier-duty application with a 1500 lb capacity at 50% compression, and I recommend these if you will be doing a lot of hauling since they have a much stronger capacity, but for occasional hauling the 1000 lbs springs are more ideal and won't give as bumpy a ride when unloaded. These springs are...

  • What is the Height and Diameter of the Spring in SumoSprings SSR-611-40
  • The spring portion of the SumoSprings Solo Custom Helper Springs # SSR-611-40 that you referenced measures 4 inches tall x 3 inches in diameter. The bracket will add another 1-1/2 inches to the height of the spring. I confirmed these dimensions with my contact at Super Springs. Suspension enhancement, like these jounce-style springs, is vehicle specific. The difference between the 2 SumoSprings you referenced are the vehicles they are designed to fit. The # SSR-611-40 springs are...

  • Recommendation to Relieve Pressure on Weight Distribution System
  • Adding a suspension enhancement system like the SumoSprings # SSR-610-40 that you referenced might help to relieve some of the pressure you are having to put on your weight distribution system, but the actual benefits will be pretty minimal. This is essentially because your properly rated WD system won't really allow the springs to even engage too much, since the system is already distributing your tongue weight to the truck and trailer. These two components can also actually work against...

  • Is There Any Advantage in Using SumoSprings With Weight Distribution on a 2016 Toyota Tacoma
  • Even though the Super Springs SumoSprings # SSR-610-40 will help to keep your 2016 Toyota Tacoma level while towing like a weight distribution system, they are meant to keep your Tacoma from experiencing too much wear and tear while under a load. They can be used with or without a weight distribution setup, and will improve your rear suspension either way. A weight distribution system is geared towards making your whole towing setup more level and safe, where the SumoSprings are a little...

  • SumoSprings or Timbren Suspension Enhancement for 2015 Toyota Tundra
  • Because the Timbrens like part # TTORTUN4 that you referenced have a reputation as having kind of a harsh unloaded ride quality I would recommend the SumoSprings part # SSR-610-40 since you will get the same support without as harsh of a ride when the vehicle is unloaded. The lighter duty SumoSprings is what I recommended as it will still give support but it would have a minimal affect on ride harshness. There a guy that works here who has had both installed on his truck and he...

  • SumoSprings Recommendation for a 2015 Toyota Tundra Towing 22 ft Camper with Dirt Bikes in Bed
  • For your 2015 Toyota Tundra I would recommend the heavier duty SumoSprings part # SSR-610-47 since you will be towing and carrying such a high amount of weight. The lighter duty part # SSR-610-40 would still help, but not nearly as much as you would need the HD version would be the one to use. You would only notice either of these springs if you were to hit a pretty large bump when unloaded.

  • Recommended Suspension Enhancement to Level 2016 Toyota Tacoma when Towing Trailer
  • Installing the Super Springs SumoSprings Solo Custom Helper Springs - Rear Axle # SSR-610-40 referenced in your question on your 2016 Toyota Tacoma will definitely help to level your vehicle and reduce the sag you are getting from your trailer's tongue weight. Once installed, these will also help to absorb bumps and shocks as well as minimize sway when towing your trailer. The springs will compress according to the weight of your cargo, which will help to maintain a smooth ride regardless...

  • Color Choices of # SSR-610-40 Sumo Springs for 2011 Toyota Tundra
  • The # SSR-610-40 Sumo Springs by Super Springs are only available in blue, as shown on our product page. They would replace the factory bump stop, located directly atop the leaf spring over the axle, so they're not going to be visible from the side. Timbren offers a similar product in black, part # TTORTUN4.

  • Would the SumoSprings part # SSR-610-4 Interfere with Fifth Wheel Hitch on 2014 Toyota Tundra
  • The SumoSprings part # SSR-610-40 that you referenced SHOULDN'T interfere with the Pullrite 3100 Superglide fifth wheel hitch since this product just replaces the bump stops of your 2014 Toyota Tundra. In general suspension enhancements like this do not interfere with fifth wheel hitches. But check out the installation instructions and picture I attached and compare how this product installs to the install brackets of your fifth wheel hitch to be 100 percent certain.

  • Are the Light Duty and Heavy Duty SumoSprings the Same Height for a 2015 Toyota Tundra
  • Yes, I would say that is a fair assessment of SumoSprings # SSR-610-47. the capacity is higher as well at 1,500 pounds. And of course it also fits a 2015 Toyota Tundra. Both it and # SSR-610-40 even share the same instructions.

  • Suspension Enhancement Recommendation for a 2010 Toyota Tundra
  • The # SSR-610-40 is the light duty SumoSpring available for your 2010 Toyota Tundra. These will have 1,000 lbs of support whereas the # SSR-610-47 would be considered the heavy duty version and would add 1,500 lbs of support. For you I would go with the heavy duty version. You should not that suspension enhancement does not allow you to carry loads heavier than what the current vehicle capacity is. It just provides more support to allow you to carry your capacity as safely as possible.

  • Dimensions of Spring Included in SumoSprings Solo Custom Helper Spring Kit SSR-610-40
  • The dimensions of just the jounce spring itself of the SumoSprings Solo Custom Helper Spring Kit # SSR-610-40 are 4 inches tall x 3 inches in diameter. These dimensions are without the included bracket and with the spring under no pressure. This kit is a confirmed fit on your 2017 Toyota Tacoma.

  • How Much Clearance Between SumoSprings # SSR-610-40 and Frame on an Unloaded 2015 Toyota Tundra
  • It's going to vary some from vehicle to vehicle just because of how your truck rides. However, I reached out to SuperSprings and they told me that a half inch to an inch of clearance between the spring and the frame is fairly standard. The SumoSprings Solo Custom Helper Springs # SSR-610-40 including the brackets are 6 inches tall. So if you need to determine exactly how much space will be between the spring and the frame of your Tundra you can always measure.

  • Which SumoSpring Kit for 2017 Toyota Tundra
  • I'd go with the lighter duty SumoSprings for your 2017 Toyota Tundra for the reason you mentioned. The heavier duty ones will be much harsher. I only recommend the higher duty ones for people who plan to be at the capacity of their vehicle most of the time when travelling. The part # SSR-610-40 would be the better option. You'll most likely have to use lower spring bar tension with your weight distribution system as well.

  • Timbren or SumoSprings Suspension Enhancement Recommendation for a 2016 Toyota Tacoma
  • For your 2016 Toyota Tacoma both the Timbren part # TTORTUN4L and the SumoSprings part # SSR-610-40 are confirmed as a fit. I would recommend going with the SumoSprings though as we have found they provide a smother ride quality than the Timbrens which tend to be a bit harsh. Both should easily last the lifetime of your truck, but the Timbren has a limited lifetime warranty whereas the Sumo only has a 2 year warranty. I would not need to see pictures of your current bump stops.

  • Suspension Enhancement Recommendation for a 2008 Toyota Tacoma
  • Both the Timbren Suspension System part # TTORTUN4 and the SumoSprings part # SSR-610-40 (which only have a 1,000 lb capacity),have been confirmed to fit your 2008 Toyota Tacoma, but I would recommend the SumoSpring kit over the Timbren because they tend to provide a smoother unloaded ride quality over the Timbrens. There is a guy here that has had both setups on hit Ram truck and he like the SumoSprings much better. He said he could hardly tell they were installed when the truck was...

  • Is It OK For Super Springs SumoSprings to Touch Frame of 2005 Toyota Tacoma when Truck is Unloaded
  • Typically, you do want a bit of space between the spring and the truck frame when the truck is unloaded. However, if your Super Springs SumoSpings # SSR-610-40 touch the frame of your 2005 Toyota Tacoma when it is unloaded it will be okay. The only thing you may notice is a bit stiffer of a ride since the springs will engage more quickly once the truck is loaded. From the install photos taken when we installed these springs on a 2007 Tacoma, it appears that truck had very little to...

  • Will Sumo Springs for Toyota Tundra Slide Off Bumper Stops
  • I spoke with my contact at Super Springs and she said the SumoSprings Custom Helper Springs Kit # SSR-610-40, which you referenced, are designed to replace the factory bump stops. The springs are bolted to a mounting bracket held down by Ubolts so they are very secure. Additionally, when you have a load on the springs they will be compressed. So no, the springs will not slide off when going down the road with a load. I have included a link to the installation details for you to check...

  • Suspension Enhancement Recommendation for 2008 Toyota Tundra
  • We have just what you would need. The Timbrens like part # TTORTUN4 will give you additional suspension support without the hassle of dealing with air bags but they do have a reputation as being somewhat harsh. What we have found is the SumoSprings like part # SSR-610-40 give you the easy, maintenance free support without the harshness associated with the Timbrens. This would be our recommendation.

  • Suspension Enhancement Recommendation For 2005 Toyota Tundra 2WD
  • For your 2005 Toyota Tundra I recommend The SuperSprings Vehicle Suspension, part # SSR-610-40. This system is designed to work with a suspension system that is in good working order and will not increase the weight carrying capacity of your Tundra. It helps prevent sagging and bottoming out when carrying heavy loads. This system is easy to install by replacing the bump stops on your vehicle. There is no drilling required for installation. They will not affect the ride of your Tundra...

  • Height of SumoSprings Campatible with 2008 Toyota Tacoma PreRunner
  • The Super Springs SumoSprings Custom Helper Springs # SSR-610-40 are confirmed to fit on your 2008 Toyota Tacoma. They will install in place of the existing factory bump stops and measure 6 inches tall. There should be some space (approximately up to an inch usually) between the helper springs and the frame when they're installed so they will not raise your truck. I've attached a video of the springs being installed on a 2007 Tacoma for you to see.

  • Rear Helper Springs for a 2013 Toyota Tacoma
  • Helper springs is a general term that can be applied to all suspension enhancement products. So what it comes down to is jounce style springs versus air bags. Jounce style springs are excellent for the same kind of load all the time, such as towing a trailer. But they also work independently side to side. Air bags are a great option for carrying different size loads in the bed. When set up for it, air bags will allow you to level the bed side to side to compensate for varying load sizes. If...

  • Weight Distribution and Helper Springs for a 2008 Toyota Tundra 2-Wheel Drive
  • Weight distribution should be used any time the gross trailer weight is at least 50 percent of the gross vehicle weight. In this case the trailer is more than half of the truck weight so I do recommend weight distribution. Weight distribution basically uses the leverage of the spring bars to apply the tongue weight of the trailer more evenly to all axles of the tow vehicle and trailer so it will help with stability and rear end sag. Suspension enhancement products help on the truck side...
