2,800-lb Capacity. Upgrade your Ford F-350 Super Duty's front suspension with these maintenance-free helper springs. Sturdy microcellular urethane springs cushion bumps and help support a heavy load to level your ride and minimize sway. No-drill installation.
Features:
Specs:
A heavy front load can cause front-end sag as your factory suspension compresses under the weight of the load. This means that the front 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 rear axle, your rear 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.
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.
The springs can also compress by as much as 80 percent to support a heavy front 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 rear 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.
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.

2,800-lb Capacity. Upgrade your vehicle's front suspension with these maintenance-free helper springs. Sturdy microcellular urethane springs cushion bumps and help support a heavy load to level your ride and minimize sway. No-drill installation.Straight forward, simple, replacement for OEM springs. These springs make contact with the lower arms all the time and definitely help dampen the bounce effect from a heavier steel bumper. Any rolling effect from uneven roadways and turning is also reduced, it feels the vehicle is more stable. For my situation, this is the first step to take before considering replacing shocks, etc., and is very economical. I'll give it more time, but I believe this is all I'll need to do. Thanks etrailer! Quick shipping!
These 1ton trucks are heavy, I went with the 8k front sumo springs. If you're lookingto soften up your ride all I can say from my experience, get you the medium to light rated sumo springs. I installed the timbren bump stops in the rear because I haul freight for a living & the front 8k sumo springs are overkill. When you hit good dips or bumps in the road its a ricochet effect.
Just got the sumosprings put on my 2017 f250, took it for a short drive the ride seemed better then it was with the factory bump stops. I also put on a set of timbern super duty bump stops earlier. I really like this product, truck rides nice and doesn’t sag when I hookup to my 14000 pd catering trailer when fully loaded. Both products well definitely make my truck ride better.
I love these Sumo “springs”. eTrailer never disappoints me. I had Stoops in Lafayette Indiana install them for me. I knew when I left the parking lot I was going to like them. Side to side sway is gone. Potholes are a slight bit harsher but is a small price to pay for the MUCH better handling I now have.

Working great after one year.
etrailer Great products you want find a better product. Fast turnaround too
Excellent, quick delivery, easy installation!! Thanks for another wonderful purchase.
when I received these front springs ( The rear are on back-order until freak'n March) having never used these things, the instructions say "take them apart" nowhere does it say "to get them apart, TWIST the adaptor plate off" ~~~ I guess Im not smart enough to figure THAT out. Installation looks super simple, when I get the stern springs installed, in a month, I'll write another, more detailed review. But for those who have never encountered this product, when you get them, TWIST (unscrew) the adaptor plate
ordered the wrong size initially but after talking to a rep from SumoSprings and realizing my mistake I was able to exchange them for the appropriate size for my needs. Customer service was excellent, and they make a huge difference with the plow on without serious effects to the ride.
Stable and smooth ride.
Excellent service and super fast shipping. I love working with these guys because it is one less thing I have to worry about. Thank you.
Extremely easy install! You will definitely have to have a floor Jack, there is no muscling the spring in without raising the frame.
These are amazing! Softened the harsh ride substantially. Wish I'd found out about these earlier....

Product still doing its job! These should have been the OEM standard when the vehicle was new. Local truck only driving, long road trips with cargo trailer and weightrough roads, all in between, these springs definitely make the ride better.
