Reduced rear axle sag with Timbren suspension enhancement

Whether you're hauling heavy loads in your bed or cargo area or towing a trailer, you will often see the rear of your vehicle sag while the front end rises. In these cases, the rear axle is handling not only the weight of the cargo, but also more of the vehicle's weight. Because less weight is on the front axle, the front tires are making less contact with the road. Overall handling - traction, steering, and braking - is negatively affected. But the resistance from Timbren's Suspension Enhancement System works with your factory suspension to keep your vehicle level and improve your driving experience.


Diagram of the Timbren spring installed

The Timbren system comes with custom-fit brackets that are bolted onto each frame rail above your rear axle. Hollow rubber springs are bolted to the bottom of the bracket and hang down to where the bottom of the leaf spring sits, 1" above the axle. The inch of clearance allows the existing factory suspension to operate normally under light loads and standard terrain, ensuring the smooth, comfortable ride that you are used to.


Action of a standard Timbren rubber spring

Timbren Suspension Enhancement Systems are designed to work progressively. When the hollow rubber springs are compressed, the convoluted design causes them to quickly collapse along the folds. Once the folds are compacted, the stacked barrel shape increases resistance, stiffening the suspension and keeping your vehicle level.


Timbren suspension system works to prevent body roll

Each hollow rubber spring works independently to support the driver's-side or passenger's-side of your vehicle. This is helpful when you swerve or make sharp turns. Each spring is activated when it is needed, so body roll is greatly reduced. The independent action also works well when you are hauling off-center loads.


Trailer swaying as it is towed behind a truck

Because your vehicle handles better with the springs, less turbulence will be passed along to the trailer and this helps to keep the trailer in line. Your driving comfort is further enhanced if the trailer does begin to sway (from a gust of wind or a passing semi) because the movement from the trailer is not transferred to your vehicle. This also works to make the sway subside more quickly.


An empty truck on a bumpy road without Timbren SES

Another great feature of the rubber construction is that the springs absorb most of the road shock, creating a smoother, more stable ride overall. Wear and tear on the factory suspension is also lessened because the rubber springs work to prevent bottoming out on rough roads.


Timbren Suspension Enhancement Compared to the Competition

Timbren's Suspension Enhancement Systems are much easier to install than air springs - there are no air hoses to run, no compressors or gauges to hook up, and no manual adjustments to make. The rubber construction makes Timbren's springs more elastic than similar products constructed of microcellular urethane. And more elasticity allows for a more comfortable ride because the rubber has more travel.

Video Transcript for Timbren Front and Rear Suspension Enhancement Systems Review

Speaker 1: Today we're going to be taking a look at the Timbren line of suspension enhancement systems. Any time that we add weight to our vehicle, it's going to put a lot of strain and stress on the suspension, especially if we're towing a heavy camper, trailer, or we have a heavy load in the back.Tends to have the back end squat down, which again, it's going to put that strain and stress on the rear suspension because not only are we asking it to hold up the weight of the vehicle, but everything else that we add on to it. Which that can arise a lot of different issues. The front end is going to be getting pulled off, which will misalign our headlights, and our tires won't have as much contact, so our steering and braking is going to be diminished.But tat;s where timbrens are going to come into play. They're going to provide us that extra support so that when we do have those heavy loads, the back end doesn't sag down quite as much, and it's not putting so much stress on the back end. By doing that, the front end's not going to rise up, which means our headlights will be in line and our tires will have the correct amount of contact and pressure, so our braking and steering isn't affected.

And they're going to do that all while making our ride more comfortable with that extra load.Our timbrens are going to provide us the support we need by replacing our factory jump stops and mounting in between the frame and the axle. Now, yours may look different, so you want to double check inaudible 00:01:20 fit guide for your specific application.Now, each one of our timbrens is going to feature a steel bracket. They're all going to have black, powder coat finish on them to resist that rust and corrosion or any other kind of chemicals that may be on the road. They're going to have a hollow, rubber ayon 00:01:36 spring that's going to take a lot of that pressure and strain off of the rear suspension.Whenever we do load our vehicle down, the space between our frame and our axle is going to get smaller. That's where our spring is going to make contact with the axle, and it's going to start compressing.

Now, they are progressively rated, so if we have a small load or a light load, it's going to have a little soft engagement. But the further it gets compressed, the harder and stiffer it becomes, giving us the support we need with those heavy loads.And since they are rubber, they're going to have a lot of give to them, which means they're going to give us the support we need. But at the same time, they're going to give us some more cushion and absorb some of the road shock as we drive. And since the rear ones here aren't in constant contact with our aXle, it is going to provide us the same ride quality when it's unloaded.Our timbrens are going to work independently from each other from side to side. That way, if we have an off center load, it will help compensate for that, but at the same time, if we take an evasive maneuver or a really sharp turn, this is going to help reduce that body roll and some of that sway feeling that we get going on when we have a lot of added weight.Our timbrens for the rear are going to be a good enhancement for any time you're going to be adding weight to the back of your vehicle, whether it be a heavy trailer, a large load in the back or any other situation where you're adding a lot of weight to the back of your vehicle.Now, timbrens on the front are going to be a little bit different.

They're going to provide us that load-leveling support and make sure the front end doesn't get pushed down too far. However, these typically are going to be in contact all the time, which means it's going to give us that support and help reduce on that body roll all the time, all while absorbing that road shock, giving us a smoother ride.Now, some situations where you'd want that extra support on the front of the vehicle to keep it from getting pushed down too much would be if you have a snow plow or winch, if you flat-tow your vehicle, or if you have any other heavy accessory on the front. This is going to make sure that front end stays where it should be, and again, making sure our tires, braking and steering acts how they should.When comparing the timbrens to other suspension enhancement options like airbags, these are going to be a lot easier to install because we're not going to have to worry about running lines, maintaining air pressure, putting in switches or compressors or any of that. Once these are installed, these are going to be completely maintenance free. However, airbags are going to provide us with a lot more adjustability, whereas our timbrens are not going to have that.That'll finish up your look at the timbrens suspension enhancement systems..

Just finished installing the TTORTUN4 Suspension kit on my Tundra. It took me, with limited mechanical ability, about an hour to install and was a simple and easy installation. My truck loaded with tools, a construction canopy, and heavy bed-slide sits up in the back like its unloaded, rides great, and handles so much better! I'm super pleased! Thanks so much! 340924

I just wanted you to know that prior to my installation, this Coachman with a hitch weight of 700+ pounds would push the rear down so much that there was barely daylight between the tire and the wheel well...but look at us now. This '04 Titan with 189,000 miles and original suspension is riding high. Your product helped me get the bed level and has reduced the sway on the trailer so much that it is hardly noticeable. I am very happy with my purchase, your follow-up and the results. 564348

I initially ordered the wrong part, # TTORTUN4L. after realizing that I needed part, "TORTUN4" I gave them a call and the change was made before shipping, and with no problems. Very professional staff and easy to deal with. The product arrived in a timely manner and as advertised. It took me about 15 minutes to install (without removing the tires). I just crawled under my 2007 Toyota Tacoma pre runner, removed only one U-Bolt , slid one end of the Timbren under the other U-Bolt and placed the U-Bolt I removed back in place over the other side of the timbren and tightened. Repeated on other side. Due to having a fiberglass camper top on the bed and custom built storage inside of the bed the timbrens just barely hit the top bracket. therefore, the ride changed slightly, but not as bad as I thought. The springs do help significantly with body roll when making sharp turns. Overall I am extremely pleased with them. Haven't had a chance to tow with them yet, but can tell by the stiffness that there will be no problem with sagging. Thanks for the great product a helpful staff. Mark 162116

20 min install tops. Took more time retorquing the nuts after loading. Couple tips: only remove the two rear nuts on each u bolt to slip out the old bump stop to replace with the timbren. Go ahead and spray those nuts with pb blaster or wd 40 to help ease removal. I used a breaker bar so it was no problem. I would suggest that once you have the timbrens in place, I would jack up the rear under the receiver hitch (I used wood blocks) and slip your socket and extension back into the bump stop to retorque the 17mm bolt. I also went ahead and retorqed the nuts once I hooked up trailer. As far as towing now, wow what a difference. Virtually eliminated all front axle hop from road dips making for a much more confident and stable ride. 26' coach, 4900# dry. Pics are unloaded and then loaded. 270693

Very easy to install. Works great. Didn’t seem to affect my ride. Levels up my rig when I put the camper on or hook up to a trailer or piece of equipment. Love it and would highly recommend it. 570299


Comments

Timbren suspension systems wont have a whole lot of effect on vehicle ride except during cornering or when the vehicle is under load. Once a load is applied to the suspension, either from cargo or from the tongue or pin weight of a trailer, the suspension will compress enough for the Timbren Aeon springs to contact the axle.

Excellent product, easy bolt on application any DIYer could install. Ride height has improved considerably while towing my trailer or hauling my tools and equipment in my truck bed, no more sagging rear springs and swaying or front end drift. 418758

The best investment, cost and performance bang for your buck that really improves the ride, I love it and would give it a 10 star rating if there ever is one.

Works like a charm! Installed in 15 minutes. Had them for a year now on my 2013 Tundra 4x4 double cab. Helps to level out the sag from the travel trailer load (although not perfect and leveling is not entirely their purpose - airbags for that if you want) and keeps the up/down undulations to a minimum on the road. Recommend them fully! 258206

Seems like a very good product, although it does stiffen the ride noticeably. It did cure the rear end sag due to my shell, lumber rack, and tools inside. Instructions were vague, but I still managed to install both in about 45 minutes. 108743

Super easy to install. After reading several reviews about this product and how folks went about installing, found that I just needed to remove just one of the U-Bolts and just barely loosened the second. Replaced both in about 30 minutes. Shipping was quick and was exactly what I ordered. Reviews were helpful and will definitely use etrailer again. 528948

I bought these as a replacement for "air bags" which I had two different sets, which failed over 10 years. i would say this product is helpful with pulling a trailer and lighter loads but from time to time I haul heavier loads and this product doesn't offer as much help/support as the air bags. This product is a little cheaper and if they don't weaken over time they will be a help. I have added additional leaf springs to two different pickups but then you end up with a stiffer ride full time. 421383

2018 Toyota Tundra

Bought these for my new 2018 Toyota Tundra. On my previous 2010 Tundra, I had installed helper springs and decided to try Timbren's this time around. I bought 1/2" spacers, since I did not want the truck to sag too much. Not sure if you can see in the pictures, but with the 1/2" spacers, the Timbren's come into contact approximately 1/2" to 3/4". They can be a bit rough and bouncy once they come into contact, but no rougher or uncomfortable than with helper springs. Over all I am very happy with how they perform. The installation was very easy. Took me about 1/2 to 3/4 of an hour. All you need is a 24" breaker bar, a ratchet wrench, and a 19mm deep socket. Unloosen the nuts enough to remove the existing bump stop and replace with the Timbren's. That's all it takes! 451415

I purchased this item to install on a 2013 Toyota Tundra 5.7L V8, 4x4. It took about a week for the product to arrive. Once I received it, I took an 18V Battery Operated Impact Wrench and removed the U-bolts from the Springs, removed the OEM Bumper mounts. Installed the Timbrens, retightened the U-bolts and torqued the bolts to factory specs. Total time to do the install, 30 minutes! Also, I want to mention that I never jacked up the truck. The ride quality is the same when the vehicle is unloaded. When I hook up to the Travel Trailer, the truck doesn't squat like it use to and I don't get the bottoming out or rocking effect when I hit a waving section of pavement when pulling the TT. I'm very happy with my purchase. 181778

I'd have to give them a good to excellent review. I'm pulling a 5,000 pound trailer with 500 pounds of tongue weight and a light load in the bed of my Tacoma. It's a stiff ride with the trailer on, but had to have something to keep the truck level, and this is probably the least expensive way to go. With an empty truck, I have to hit a very hard bump for the frame to hit the Timbren, thus the ride is the same as it was before I put them on. 243664

These are great! Dont change the ride at all when not in use and make towing my 7000lbs trailer so much more comfortable! Tow with confidence. Easy install took ten minutes with my buddy's lift. Could have been done easily on the ground too. Improves handling and ride when towing 614909

Purchased for a 2008 5.7 l Toyota Tundra. As advertised. Installed in one hour. Performed as described with an unload bed- slightly stiffer with less recoil over rough roads. Hitched the fifth wheel to the Tundra and took a one hour trip over varying road conditions. Performed exactly as I hoped. Couldn't be happier. ETrailer processed the order on the same day and I received it on the afternoon of the third day. Could not be more pleased. 109677


Comments

Thank you for your follow up inquire on the Timbren suspension parts for my 2008 Tundra. I used the vehicle for the past year to tow a Heartland fifth wheel. The parts worked as advertised and I have been happy up til I sold the Tundra. The service I received at Etrailer led me to purchase towing base plate and bar for my dinghy on our next RV. Its a pleasure dealing with Etrailer!

I recently ordered and installed this suspension enhancement for my 2017 Nissan Titan SV 2WD, Crew Cab. I will be road testing it next week with a heavy duty 20' flat trailer, carrying a 2,800 lb car, 500 lb 4 wheeler and misc items for an estimated total of near 6.5-7k lbs of trailer weight. In addition, I might be carrying a 450 lb go-kart in the truck bed. I feel this will be a good test of the products' capability and performance. Approximately 2 weeks ago, I towed an 8.5' x 20' cargo trailer weighing out at nearly 9k lbs on the same 500 mile trip. For that trip, I had the stock suspension setup and used a weight distribution (WD) system. The trip went smoothly, but I'm hoping that this suspension enhancement will eliminate the need to go through the WD hookup process. A followup review to come. I've given this a 5 star review due to the excellent customer service I received from Ashley. I was traveling back down to Florida from up north and had questions regarding compatibility with my truck. She called the company, Timbren, to verify that it would work and answered all my questions, since I was driving at the time. She even pushed the order through quickly and got it out that same day. I was amazed when I received it yesterday, less than 2 days after I ordered it and installed it in less than an hour. This is truly an example of the excellent level of customer care that etrailer provides its patrons and exactly why they are my first choice for all my trailering needs. Thank you. 725798

This product has made my Tundra less saggy when towing, doesn't bother the factory ride when empty. Very easy to install, only took me 30 minutes. The Tundra tows great anyway, but now is less saggy. I hauled my 4 wheeler and a 30 ft. trailer and it felt and looked great. Would recommend this product definitely. 720712

I pull a 31' travel trailer with a 2017 Tundra. These have made a noticeable difference in how high the back of my truck sits and has helped reduce swaying while towing. I enjoy the fact that when I'm not towing it does not affect the ride. I would definitely purchase them again for my next truck. 698016

Great product and quicker than promised delivery from etrailer. THANKS. The install was longer than many bragged about. Mine is a 2002 4.7L Toyota Tundra 4x4 and is mostly used to pull our tent trailer. Without power/air tools in my driveway, I needed a friend's 3/4 inch drive ratchet set, bleeding control equipment and almost endless swear words. Each side took about 45mins a side and the instructions and videos were understandable and straightforward. All said, I am happy I have added these to my Tundra. 679857

Installation was very easy and the result was exactly as expected. I recommend this product to anyone who might be anticipating some potential overload situations. I installed these prior to purchasing my 30 foot travel trailer and reaped the benefits on my last trailer trip when the back road, although paved, unexpectedly had a few dips. The overloads absorbed the shock from a bouncing truck and trailer nicely. 673340

I've had these on my '16 Tacoma for a year now. When the truck bed is empty, the ride is harsher than before, but not intolerable. When I'm loaded up for hunting (lots of heavy gear, maybe an elk, plus towing a pop-up camper), it's perfect--never bottoms out like it used to. I keep 120 lbs. of sand back there all winter for added traction in the snow, and that helps to smooth out the ride a bit. This photo with sagging rear was BEFORE the Timbrens--now it rides level. 590484

  • Recommended Timbren Rear Suspension Enhancement for a 2010 Toyota Tacoma With 4WD
  • There are a few different options that we have for you to install a Timbren Rear Suspension Enhancement System on your 2010 Toyota Tacoma that is 4WD. Please keep in mind that any suspension enhancement system will not increase your weight capacity. It is meant to supplement a suspension system that is in good working order. You should never exceed the weight-carrying capacity of your vehicle. If you plan on driving places that might not have a road then I recommend going with the Timbren...

  • Differences Between the Timbren and SumoSprings for a 2012 Toyota Tundra
  • For your 2012 Toyota Tundra CrewMax, you will want to use part # TTORTUN4 for the Timbren Rear Suspension Enhancement System or part # SSR-610-47 for the SumoSprings Solo Custom Helper Springs. Both of these options will provide you with additional support that will help to reduce rear end sag while towing. They will also both work to reduce body roll, improve stability, and increase the life of your existing suspension components. The Timbren springs have a weight capacity of 6,000...

  • Comparing the Timbren Suspension Enhancement System and the Air Lift AirCell Helper Springs Kit
  • For your 2007 Toyota Tundra, I highly recommend the Timbren Rear Suspension Enhancement System part # TTORTUN4. The Timbren springs will be much more durable than the Air Lift AirCell Custom Helper Springs Kit part # AL52210. The durability will result in more support and a longer life. The Timbren have also produced much greater feedback from our customers and are currently one of the most popular suspension enhancements we carry. I have attached a review video of the Timbrens for...

  • Recommended Timbren Suspension Enhancement System for 2010 Nissan Titan
  • Since you are towing a travel trailer, you are going to want to use a Timbren system that enhances your rear suspension. Should your 2010 Nissan Titan be a 4 wheel drive model you would want # TNRTTN, and for 2 wheel drive models you'd want # TTORTUN4. This system is going to level out your ride and help reduce sag when hauling heavier loads. They install without requiring drilling and replace your axle's bump stops. I've included a photo showing what a Timbren looks like installed on...

  • Suspension Enhancements for a 2017 Toyota Tacoma with Firestone Airbags
  • I do have a suspension enhancement option for your 2017 Toyota Tacoma that is compatible with the Firestone Ride-Rite Air Helper Springs part # F2407, however, the Timbren Rear Suspension Enhancement System part # TTORTUN4L and the Roadmaster Active Suspension Kit part # RAS4514-SAT will not work. In order to use a set of suspension enhancements with your currently installed Firestone Ride-Rite Air Helper Springs, I recommend the TorkLift StableLoad Rear Suspension Upgrade part # TLA7311...

  • Will Rear of Tacoma Still Sag with Timbren Rear Suspension Enhancement System
  • Jounce-style rear springs definitely offer the easier install (and maintenance thereafter) compared to air bag kits like the Firestone # F2410 you referenced, however they aren't the best option if your main concern is rear sag from a trailer's tongue weight. As you mentioned, there's still going to be a gap between the spring and contact point when the Timbren # TTORTUN4 is installed on your Tacoma and this is by design. If there wasn't a gap your empty ride would be really rough. I...

  • Recommended Timbrens for a 2018 Toyota Tundra with 3 Inch Lift Kit
  • For your 2018 Toyota Tundra, I recommend using the Timbren Rear Suspension Enhancement System part # TTORTUN4 with three of the Timbren Spacer For Raised Frame Vehicles part # TA25723-90AD00 stacked. Assuming you have a full 3" suspension lift and not a body lift, this option should give you 1/2"-1" of clearance but the spring measures 3-3/4" tall so you can can always measure to be certain. Please keep in mind you will need to obtain longer M10 bolts from your local hardware store to install...

  • How To Prevent Sag on a 2001 Toyota Tundra TRD 4x4 While Towing/Hauling
  • I do have an option for you but I checked with Firestone and you are correct in that they do not list the Firestone Ride-Rite Air Helper Springs part # F2245 as a fit for your 2001 Toyota Tundra TRD 4x4. I also checked with Air Lift and they do not offer any airbags for your vehicle either therefore I recommend taking a look at either the Timbren Rear Suspension Enhancement System part # TTORTUN4 or the SumoSprings Solo Custom Helper Springs part # SSR-610-47. The Timbrens and SumoSprings...

  • Recommended Transmission And Oil Cooler For 2015 Toyota Tacoma
  • The Derale Series 8000 Plate-Fin Transmission Cooler Kit w/Barb Inlets - Class III - Efficient # D13503 is a great choice for your 2015 Toyota Tacoma 4x4 with 4.0L V6 and the plate-fin is a good way to go. The internal turbulator agitate the fluid to facilitate heat transfer and prevent any undesirable drop in pressure. For your engine oil cooler, I recommend the Derale Plate-Fin Engine Oil Cooler Kit w/ Adjustable Sandwich Adapter (Multiple Threads) - Class V # D15405. This is the...

  • Brake Controller and Suspension Enhancement Recommendation for 2006 Toyota Tundra
  • For a brake controller I would recommend the Prodigy P3 Brake Controller part # 90195. This is our best selling brake controller because of how well it works and how easy it is to setup. This is a proportional brake controller that senses the amount of braking the tow vehicle is applying and applies a proportionate amount to the trailer brakes. This will be the last brake controller you buy. It can easily be transferred to future vehicles as well. To install the controller all you need...

  • Height Of Timbren Springs and Vertical Wheel Travel Loss In 2019 Toyota Tacoma
  • When installing any Timbren system on the 2019 Toyota Tacoma you should have about 1/2" to 1-1/2" between the frame and the spring after installation. You won't necessarily be losing wheel travel when you use a Timbren Rear Suspension Enhancement System on the Tacoma. I recommend either the # TTORTUN4 system if you have 4 leaf springs in the rear suspension or # TTORTUN4L if you have 3 leaf springs in the rear suspension. When you switch out the factory bump stops for the Timbren springs...

  • Comparing Timbren Suspension Enhancement for 2018 Toyota Tacoma
  • There are six different Timbren kits for suspension enhancement that all fit your 2018 Toyota Tacoma. Four are for the rear and two are for the front. Of the front two, part # TTOFTUN4 is designed for adding support when you put a snow plow on the truck and # TABSTOF is an active bump stop that cushions the shock when off-roading. A couple of the rear kits are designed to support the rear of the truck when either towing a trailer or adding weight in the bed. Use part # TTORTUN4 if...

  • Can the SuperSprings and SumoSprings Be Used Together On a 2007 Toyota Tundra
  • I do have an option for you but the SuperSprings Custom Suspension Stabilizer part # SSA4 and SumoSprings Solo Custom Helper Springs part # SSR-610-40 cannot be used together on your 2007 Toyota Tundra as the SuperSprings block the u-bolts needed to attach the SumoSprings. If you were to remove the SuperSprings part # SSA4 and then install the SumoSprings part # SSR-610-40 you would not be gaining any support as they are only rated for 1,000 lbs and the SuperSprings are rated for 1,100...

  • Recommended Timbren Rear Suspension Enhancement System for a 2017 Toyota Tacoma with 4 Leaves
  • For your 2017 Toyota Tacoma, I recommend using the Timbren Rear Suspension Enhancement System part # TTORTUN4 because you have 4 leaf springs. If you had 3 leaf springs then you would want to use the Timbren Rear Suspension Enhancement System part # TTORTUN4L. The bump stop attaches to the top of the leaf spring pack and makes contact with the bottom of the frame rail. If this distance has been altered with the leveling kit you have installed on your truck, then you will need to use...

  • Does the Bump Stop of a 2011 Toyota Tacoma Get Removed to Install Timbrens
  • What you have found on your 2011 Toyota Tacoma is the bump stop, or jounce bumper. This will get removed to install the Timben part # TTORTUN4 that has been confirmed as a fit for your 2011 Toyota Tacoma.

  • U-Bolt Torque Rating for Installing Timbrens on a 2008 Toyota Tundra
  • I did some checking and it looks like the torque spec that Toyota recommends for the suspension U-bolts of your 2008 Toyota Tundra is 74 ft lbs. That is how much torque you should use when you are installing the Timbren system part # TTORTUN4.

  • Height of the Rubber Spring of the Timbren kit part # TTORTUN4 and # TORTUN4L

  • Can Andersen Ultimate Connection Part # AM3200 Be Used with 2016 Toyota Tundra
  • As long as you have a set of fifth wheel rails installed in the bed of your 2016 Toyota Tundra the Andersen Ultimate Connection part # AM3200 can be installed and then attach to your fifth wheel pin box. For a set of rails confirmed as a fit for your 2016 Toyota Tundra you'd want the part # RP50084-58. This is a custom fit rail kit that would minimize drilling when compared to a universal one.

  • Can both a 1 Inch Spacer and 1/2 Inch Spacer be Used Together for Timbren Helper Springs
  • Yes, you can use a 1 inch Timbren spacer, # A25723-90AH00, with a 1/2 inch spacer, # TA25722-90P00, to get to the height you need for your 2015 Toyota Tundra.

  • Overall Height of Timbren Suspension Enhancement Springs # TTORTUN4 for a 2010 Toyota Tacoma
  • I went out to the warehouse and actually pulled 2 possible fits for your 2010 Toyota Tacoma. First, for Timbren springs # TTORTUN4, the overall height from the bottom of the bracket to the top of the spring is approximately 5 inches. The other kit I pulled was # TTORTUN4L. This kit is a bit shorter at 4-1/2 to 4-5/8 inches tall overall. I have included links to hte isntructions for both kits as well as a link to our FAQ article on Timbren systems for you.

  • 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...

  • Rear Axle Suspension Kits Compatible with B&W Gooseneck Hitch in 2010 Toyota Tundra
  • The Firestone Ride Rite air bag kit that fits your 2010 Toyota Tundra Limited, part # F2445, is not compatible with 5th wheel or gooseneck hitch installations. The same is true for the Air Lift kit that fits your Tundra, part # AL88299. Since these air bag kits cannot work in your truck you might want to consider a set of jounce helper springs like Timbren # TTORTUN4 or a Custom Suspension Stabilizer and Sway Control Kit like # SSA4 from Super Springs. Both of these work with your gooseneck...

  • 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...

  • Suspension Enhancement for 2010 Toyota Tundra that Allows B and W Companion Hitch to Install
  • The Air Lift kit part # AL88299 you have installed in your 2010 Toyota Tundra is not compatible with any fifth wheel or gooseneck hitch brackets. To install the B and W Companion part # BWRVK3500-5W with the rail kit part # BWGNRK1257-5W will require you remove the Air Lift and go with a Timbren suspension setup like part # TTORTUN4 as it would not interfere.

  • The Air Lift LoadLifter 5000 Air Helper Springs, # AL88299, may work with your custom 5th wheel frame brackets, but the fit will depend on how the brackets attach to the frame of your 2010 Toyota Tundra 4x4. The LoadLifter brackets attach to the bottom of the frame and hooks to the inside of the frame and the jounce bumper bracket using clamps (see photo). As long as the brackets for your fifth wheel hitch do not interfere with this location on your vehicle frame, you will have no problem...

  • Compatibility of a Rear Suspension Enhancement System with an Equal-i-zer Weight Distribution System
  • We typically do not recommend adding suspension enhancement when a weight distribution hitch is being used. A rear suspension enhancement system such as the Timbren springs and a weight distribution hitch reduce sag at the rear of a vehicle. In some situations, they can work against each other and hinder each others effectiveness. If the Equal-i-zer system is set up correctly, you should not need additional suspension enhancement. If you are still experiencing some sag, I would recommend...
