Features to know about

Stay Level and Confident Under Load: 1,500-lb Rear Suspension Support

Heavy trailers, campers, or bed loads can make the rear sag and throw off your steering and braking. These SumoSprings Solo Custom Helper Springs add up to 1,500 lbs of support at 50-percent compression to help level your ride and improve traction when you’re hauling. They work with your factory suspension to keep weight balanced front to back so your truck stays stable and your headlights stay aimed where they should.

Smooth Out the Ride: Progressive Load Control

The progressive spring rate in these microcellular urethane springs means they compress easily for light loads and get stiffer as weight increases. That keeps the unloaded ride soft and comfortable while still giving solid support when you’re towing or hauling. You get cushioning over bumps and less bounce without the harsh, bottomed-out feel you get from rigid setups.

Comparison image showing SumoSprings Solo Custom Helper Springs installed on a rear axle, one compressed under load and one uncompressed, illustrating how the springs support vehicle suspension and maintain level ride during towing or hauling.

Stay Steady in Crosswinds and Turns: Independent Spring Action

Each spring works on its own side to balance uneven loads and keep the truck steady through turns or crosswinds. By reducing body roll and sway, the springs help you stay confident on winding roads or when a gust from a passing semi hits. The result is smoother control and a planted feel even when the bed or trailer weight isn’t perfectly centered.

Skip the Air Lines and Maintenance: Simple No-Drill Install

Unlike air systems that need compressors or pressure checks, these helper springs are completely maintenance-free. They install easily with no drilling required—no airlines to route or fittings to tighten. Once mounted, they compress vertically with minimal side expansion so they fit cleanly in tight spaces without risk of rubbing nearby components.

Built Tough for Real-World Conditions: Durable Microcellular Urethane

The closed-cell urethane material holds up through oil, salt, and UV exposure while performing in temperatures from -25°F to 200°F. That means dependable suspension support whether you’re driving through winter slush or summer heat. The solid construction gives lasting stability and support trip after trip without sagging or leaking.

So far so good. I am pleased with the way they have leveled off my truck. It was an easy install. I didn’t even have to remove the tire to get them on. It was a simple lift of the frame.

One of several purchases from etrailer and all have been positive. The Springs got here today as promised and were what I ordered. Jacked the Titan up one side at a time, secured it with jack , brakes, jack stand. Removed tire and removed the old stop. installed the new sumo springs that were somewhat larger than the oem and reinstalled the tire etc. Did the other side and was done in about 30 minutes. Looking for great service from this product and see no problem. Just what I was looking for. Thanks etrailer!

Excellent !! Install took about a half hour and took a test drive with my trailer attached, and a noticeable difference, no noticeable sag on my truck and felt very secure.
And etrailer was very fast to ship, ordered Monday and was here by Thursday! Thanks again for another great product and fast shipping

by: Henry 10/24/2024

The sumo springs we easy to install. I would recommend that you include removing both rear tires, it makes the installation so much easier. It can all be done sitting on your mechanics roll around seat.

2013 Jeep Wrangler Unlimited

I put these on a 2013 Jeep JK (not lifted) that tows a 3000 lb trailer in rough terrain; Total game changer.

These replaced the anemic factory stops (which had completely disintegrated) and make it impossible to 'bottom out' on the dips and holes that use to beat up the suspension. I got nearly all of my vertical travel back and the vehicle now sits almost level under high tongue load.

They go on pretty easy. I suggest sliding in one side, and then using a wooden dowel and hammer to pop the other side in the stock receiver cup.

Highly recommended. These are a MUST if you are towing a trailer (with a medium sized SUV) of any significant weight or if you just want to be able to bounce hard without bottoming out your suspension. I am likely going to get the front suspension version now as well.
Wish I knew these existed sooner.

Wow thank you for the glowing review Randall. It sounds like once you got them installed they are working out great. That sunset is gorgeous, where were you in this photo?

2025 Promaster 2500 159” wheelbase. Backed the van on couple 2” X 6 “ easier sliding under. Sprayed PB Blaster on top of bumper spring, using a 16” Channel Lock, easy off with the old. At that time I jacked the rear end to allow clearance. One side at a time. Took longer for set up then the job. I used the long bolt with two spacers. Have not drove yet, though looking for great results.

Glad to hear the install wasn't too bad, Michael! Definitely let us know how the ride is once you take it out for a drive! What are you using your Van for? The tires look pretty beefy.

This only pertains to the order, shipping speed, and install as I have not put a heavy load on these sumo Springs yet but I feel like that's a foregone conclusion based off the reviews already. The ordering process, the shipping, and the installation was unbelievably easy. I kept rereading the instructions thinking this can't be right because it was so simple. I looked at the YouTube video and realized it is that simple! So happy with the ordering process, the quality of the initial product I opened, and how simple it was to put on the jeep.

That is the beauty of SumoSprings! Super easy to install and once they're on you can forget they're there! Are you planning on towing something with your Jeep that you want extra support for?

Justin

9/1/2026

@ClaireH yes Ms Claire. I plan to put a truck camper on the Jeep (that weighs in the 500-1000 lbs range). My payload is 1700 lbs so I know a camper of the weight will be significant my truck. Already ordered a stiffer rear anti-sway bar as well.

Claire H.

@Justin That sounds like a good plan! These SumoSprings plus the sway bar should be more than enough to handle the weight of your truck bed camper.

Love them! The truck barely even squatted, had two dirt bikes, and a generator in the bed as well! It handles the bumps and sway great

It arrived pretty promptly about 30 minutes later I had him installed. It took me longer to find the proper Tools. Never had to remove the tires or wheels the only time I had to jack it up was to put the helper springs and screw them down very easily install

2000 Nissan Leaf

Great product! Bought these for my 2000 7.3 f250. Didn't want something that is constantly active like ras or hellwig since my leaf springs are new and rated for 4k pounds. Installed these in 1 hr super simple only hard part was the factory bump stop on driver side was a pain. Didn't install the puck they give due to height of truck and I knew more or less at what point I wanted them engaging. I haul cattle to shows/ auctions or between pastures with my 24ft big bend and these things actually provided a smoother ride in my truck loaded then unloaded.they do a great job with the added support and are better than an overload spring with handling sway and providing a smooth ride loaded. Just wish I could use the 3k pound rated ones on this truck and my dually but doesn't fit if you have a gooseneck sadly so will probably have to go with timbs on the drw. Over all great product can't speak to longevity but solid for the time being. And customer service with this company is excellent if you have a question or problem they're on top of it...hope they pay them as well as the reputation they're building for them.

I put a set of 47s on my Silverado 1500 and towed my dump trailer that weighed 6000 pounds the way I had it loaded for 50 miles on all kinds of roads and it worked well. I didn’t use the spacers and the truck still rides like it did before the install.

Recommended SumoSprings for a 2021 Nissan Titan P4X
Thanks for the picture! I am not sure how loaded down you are but your truck and trailer look pretty level. If you're experiencing squatting issues and are sure you have the right capacity weight distribution hitch then yes, adding the SumoSprings Solo Custom Helper Springs item # SS95GR to your 2021 Nissan Titan P4X will benefit you. The SumoSprings item # SS95GR have a 1,500 lbs load leveling capacity. The best part about SumoSprings is that they work off a system called progressive...

Comparing The Timbren # TNRTTNB And # TNRTTN For A 2024 Nissan Titan SV
Hey Mitchell, The Timbren Suspension Enhancement System # TNRTTNB is designed specifically for Pro 4x models so it wouldn't be the right fit for your SV. Both the # TNRTTNB and # TNRTTN (which would be a fit for your SV) have 5" tall springs. The # TNRTTNB uses HCS M8 x 50 x 1.25 Grade 8.8 zinc coated bolts and the # TNRTTN uses HCS M10 x 40 x 1.5 Grade 8.8 zinc coated bolts. These both have a 6,000lb capacity and will make a significant difference to your unloaded ride quality. I personally...

Timbrens or SumoSprings. Which One is Better for a 2020 Nissan Titan 4WD?
I strongly recommend going with the SumoSprings Helper Springs item # SS95GR over Timbren's like item # TNRTTNB for your 4WD 2020 Nissan Titan. Both systems will support your rear end and keep your truck level while towing but you won't notice the SumoSprings when you are not towing. The Timbren's will be rough and stiffen up your suspension. You'll feel them going over every bump. I have linked a review video below.

Should I Use Timbren Or SumoSprings Suspension Enhancement On My 2020 Nissan Titan Pro-4X?
You are on the right track in looking for jounce springs, as this will reduce your Titan's rear sag and also improve the overall handling of the truck while reducing body roll. Jounce springs are also very easy to install and require no maintenance, unlike air bags. When deciding between Sumo Springs and Timbren, it really comes down to how much weight you will be adding to the bed of your truck. It sounds like SumoSprings Solo Custom Helper Springs - Rear Axle # SS95GR is the kit for...

Best SumoSprings For 2023 Nissan Titan
Between the 1,500 lb SumoSprings # SS95GR and 1,000 lb SumoSprings # SS35GR that fit your 2023 Nissan Titan, the best option is the latter, the 1k springs: - SumoSprings Solo Custom Helper Springs # SS35GR The 1,000 lb capacity is more than enough support for the '23 Titan's suspension, and they aren't as dense as the 1,500 lb springs, which means they aren't going to be as stiff so you'll get a better ride.

What is the Height of the SumoSprings Solo Custom Helper Springs # SS95GR?
The height of the SumoSrpings Solo Custom Helper Springs # SS95GR is 5-1/2 inches without the top bolt and 6-1/2 inches with the top bolt. I went ahead and attached a diagram of these dimensions to give you perspective. If you need the confirmation for a fit with your vehicle, I would be happy to assist you if you provide your year/make/model.

These springs are confirmed to fit your 2017 Nissan Titan SV.

Jounce Bumper Suspension Enhancement Recommendation for a 2021 Nissan Titan
Thanks for reaching out and all of the information, Dusty! With everything you said, I believe the best suspension kits for your 2021 Nissan Titan will be the Timbrens: - Front # TFXF1004A - Rear # TNRTTNB The heaviest-duty SumoSprings for your truck is the Black Kit # SS95GR rated for 1,500 lbs.

Is There A Spacer Available For A SumoSprings Solo Helper Spring On A 2019 Nissan Titan
As you mentioned your 2019 Nissan Titan being a work truck there will be another option, but there is no spacer available for the SumoSprings Solo Custom Helper Springs # SS95GR, unfortunately. With that said, as the # SS95GR is rated to 1,500 pounds of capacity, you may want to go with a higher rated product, like the Timbren Rear Suspension Enhancement System # TNRTTN. This will have a 6,000 pound capacity and will do a better job for getting rid of the sag, but I do have to mention...

Timbrens or SumoSprings for 2019 Nissan Titan
Since Timbrens are notoriously harsher than SumoSprings and the truck will be unloaded for most of the year I would recommend the SumoSprings for your 2019 Nissan Titan with the part # SS95GR. This will give you the support you are looking for without destroying your unloaded ride quality.
