I've never put on a easier product. I put the jack under the trailer hitch mount. Just lifted the body 1-2 inches and used a 12 mm socket . The socket removed the old ones and I hand tightened the new on. Literally took 10 minutes and a beer.3575287

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.3489629

I bought and installed the 1000lb Sumo Solo springs to help alleviate rear end squat on my 2024 GMC Canyon Denali when pulling my boat. My boat trailer has a long mono tongue with no weight distribution installed. The boat weighs in at about 5500lbs, the truck fender lip measures 38” high unloaded, once I dropped the hitch down on the ball and the Sumos picked up the load, the fenders measured 36.25” equating to an inch and 3/4 squat. Empty the Sumos have an apx gap of 7/8” above the frame rails. The Sumos were recommended over the Timbrens for my situation of infrequent towing with this truck and to maintain the best ride possible when not towing. So far my ride is virtually unchanged when empty and feels controlled when towing. Installation is straight forward but the instructions could be a little clearer with a diagram showing the intended location of the springs. Luckily an etrailer customer had already done the install and provided some pics so there was no question. I chose to remove the tires to have good access and I’d do it again this way. I supported the truck with a jack stand under the receiver. IMHO the proper method to locate the over frame upper clamp brackets is to push the forward clamp as far forward until it contacts the bed stiffener and you’ll be in the correct location then let all the hardware hang to position itself, tighten as required and enjoy.1771904

Installed these right before a long road trip, and were impressed with how much the ride improved. Opted not to include the spacers, which has worked out fine. While not towing have not noticed any change to the ride, which is good. When towing the steering has a solid grip on the road now (sometimes felt a little loose before installing these) and no more issues with 'porpoising'. We drove across a several mile long bridge in the Bay Area that likely would have been a roller coaster ride previously, and had no issues. Quick and easy to install.3587884

Put these on a Jeep Gladiator to haul a motorcycle to Sturgis. Kept everything level, good ride and stability. Highly recommend.3584483

Product is great, exceeded my expectations. Install is simple and straightforward. It’s a night and day difference in both the body roll and the handling small bumps all the way up to off-road conditions.3596661

I had installed this model SumoSpring on my 2019 4Runner and had great results when towing the camper I had at the time. They greatly reduce the bounce when going over dips in the road at highway speeds. Now I have a 2021 Titan and a bigger heavier camper. I expect the same great results on the Titan. Installation was pretty straight forward and took about a half hour. The size difference between the OEM bump stops and the SumoSprings alone should give a better ride when towing my camper.3174937

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 great3547840

I got the springs installed last week and wanted to have a drive time before I wrote the review.
The height of the springs are perfect for my 2016 Tacoma, They keep the truck stable and nearly eliminate the body roll I had before installing them. I am heading to the mountains in a couple weeks, so I will update the review when I get back. That way I will know for sure the body roll is gone and the truck is stable on the winding mountain roads.
The springs installed in no time at all and since I had the rear end apart, I decided to add the leveling blocks at the same time, to keep the truck from squatting with the gear I haul around with me.
The guys at etrailer are great. And while I did not call them to discuss this item, they have been very helpful in the past with all my questions.
Below are pictures of before, a couple comparisons and after. Sorry if they come out sideways.
These Sumo Springs were a great addition to my Tacoma and well worth the money, IMHO.3179658

Opted for the Blue 1000lb Sumo's w/spacer over the 1500lb Black ones. 1500 Silverado Max Tow & reduces squatting by 2" on a 1000lb+ tongue weight. Ride is still good, but you can feel the Sumo's engage over large dips or bumps which is not an issue for me.3262392

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.3542076

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.3605434

Work great still a good ride . Pull a 32 ft 5th wheel behind a Ford Raptor no sag or sway .1427968

Ordered these for my 2018 Ford Raptor which is mainly used as an everyday and long road trip vehicle. First test run I installed the spacers that came with it. Was a bit bumpy without a load on it. Took a whole 5 mins to take the spacers off and so far she feels normal without the load. Keeping the spacers under the seat incase I need to haul a real heavy load again. Overall really great product, durable, easy assembly and no need for hassling with airbags. Definitely was worth it! I have peace of mind now that my shocks won't wear out or bottom out when hauling a load.898222

The SumoSprings have worked great! I have loaded down my Ford Raptor truck many times now. This includes towing a horse trailer, loaded hay trailer, and pontoon boat. All times the Sumosprings prevented my truck from "squatting" too much. I am glad I purchased them!1295377

These were shipped to me mid-trip so I had a good chance to do a before and after with same loads/ same roads for 3100 miles. They were easy to install (in my daughters driveway) in about an hour with one reluctant bolt in the original bump stop. I did not install the hard spacer, I figured I’d add it later if needed. I was able to do the install w/o jacking up the whole truck using a 1 1/2 ton jack under the hitch receiver w/ a jackstand next to it. I needed just a few inches as there’s lots of room under the stock height truck (I was lying on a piece of cardboard). The helper springs didn’t quite touch the axle when the jack was removed. When I first drove it in town with the Sumo’s on it they were not really noticeable. When loaded up with my 22’ Livin’ Lite Axxess trailer (4300lbs with 650lb hitch weight) the rear end would squish into the overload springs a good 3/4” but the truck was about level w/o rear end sag.
Driving home over many of the same roads I noticed it was better over railroad crossings and rhythmic bumps on the highway that previously pitched it fore and aft. The trucks manners were much better overall during big hits (like hitting a curb- yup) and pulling off-highway. The trailer is low so it doesn’t go very far off road so I can’t report on that.
Overall for ease of ordering, of install, simple usage w/o need of airlines and effective control of the rearend of the truck and the trailer I feel they deserve the 5 stars.1590937

I have a 2018 Ford F150 RAPTOR. Although the towing capacity for the Raptor is 8200 lbs, personally I won't take it much past 6000 lbs in order to be safe and be easier on the engine. I've included a picture of my Raptor with my 5800 lbs Coachman 23LT ADRENALINE toy hauler trailer with a BLUE OX SYSTEM weight distribution hitch. With the SumoSprings Solo Custom Helper Springs - Rear Axle - as you can see in the picture - I get no squat whatsoever -- in fact, I'm still sitting up with a slight downward rake while towing. When I hit potholes or bumps, I really don't feel the SumoSprings compressing and keeping the suspension stiffer. Actually, I don't feel the SumoSprings at all. I have very little sway, except when I'm doing 65 mph and an eighteen wheeler passes me, I get an ever so slight pull toward the big rig from the low pressure it creates as it pushes air out of its path, but I simply add a little bit of steering opposite the eighteen wheeler and it immediately straightens up and stays straight. Overall, I am impressed with SumoSprings and I would never ever tow anything again without them, because it stops the sag. (About 20 yrs ago, I used to get oncoming bright lights constantly flashed at me in the old days because my trailer caused my truck to sag and the front end lift, and people thought I had my bright lights on all the time).3148528

2013 Ford SVT Raptor
Aftermarket Deaver +1 Leafs
Aftermarket SDHQ Bump Stop Pads
Install was a breeze, 25 minutes, 2 wrenches and a socket.
Used the 1” Spacer for additional preload.
Gives me about 1 1/4” of open travel(bounce) before the Sumos make contact. Loaded up my RTT and camping gear along with the fam and the Sumos kicked in. Feels like I have a Sumo Wrestler on each corner of the frame in the rear supporting my load. I was looking for assistance in the rear to reduce the squat. Tried Firestone Air Bags, didn’t work out. Bought into RoadActive Suspension, doesn’t work with aftermarket leafs. Sumo was a desired choice but I felt iffy about the concept.
Happy with the outcome. I’m sure the truck is happy as well.3374672
