Specs:
Most OEM coil suspensions have a difficult time supporting heavy front loads like winches, brush guards and snowplows. If your coil springs are totally squished under a load, the lack of shock absorption can be harsh on your backside, especially if you spend long hours sitting in your vehicle while clearing snow. Insert these helper springs in between the individual coil loops in your front coil springs to help defeat driver fatigue and to better support heavy front loads.
Each doughnut-shaped spring has H-shaped channels at the top and bottom that fit to a rung of each coil in your front coil springs. Inside each round spring, a core of microcellular polyurethane foam adds cushioning between your coils. The cushioning absorbs shock, but also works progressively to better support front loads, and it keeps the front end more level. Unbumpify your ride with these SumoSprings for coil suspensions.

Great for trucks with snowplows.This one year review. We have a 2018 Mercedes Metris, it's just a big mini-van, but not a sprinter. The suspension is fairly soft, ok for city driving, but a little soft for 70+. When hauling a trailer we would gently sway, not great, so we got the rear set and it helped quite a bit, we followed with the front set 3 weeks later.
Overall it firmed up the suspension enough to really help without it being too firm. It raised the stance about 1/2" and is relatively easy to install.
Would buy again.
There is a significant improvement in ride comfort and reduced response to high winds and 18 wheelers as they pass, increased stability in turns and, overall, a more comfortable and secure ride. I'm 72 and installed both front and rear alone in under 1.5 hours. Great investment. PS We have a class B, Dodge Ram Promaster 1500 van.
Just returned from our first trip after installation of coil spring suspension- front axle and SumoSpring Solo Custom Helper Springs-rear axle. A significant difference is noted in ride as there is less bounce and sway. Cornering is more sure and flattened this noted on many curved mountain and rural roads traveled in Western and Central PA. Turnpike travel was smoother as road tar strips were not as notable given a stiffer ride.
Excellent service
Davine was awesome
I have traveled over 10,000 miles and feel that Sumo Springs for the front axles have been a great addition to my 2014 Winnebago Trend. I also added the Sumo Springs to the rear and new shocks. The ride and stability is much better with all these improvements. I would recommend all these products
Install was a breeze. Leveled out the bouncy front end on my pro master 2500. Well worth it
Easy to install on a Ram Promaster. Good instructions. Definitely improved ride quality - less sway and more stability.
product is good as always and etrailer is superb in assisting customers. 5 stars.......
Relatives easy to install. The handling has become more stable with less lean since I’ve installed these springs on my RV. Very happy with the purchase.
A noticable improvement in the ride. Very happy with them.
Easy to install, Ill put some miles on them and update.
Thank you very much. I got my order. Perfect service. Alex. Calgary.
We installed the rears first and the difference was impressive. Going to install fronts tomorrow.
Product is as described. I will post an update as soon as a pop them in and roll with them for a while.
Better handling/ Highly recommend
Easy install. Fast shipping.
Excellent service as usual
Review from a similar SumoSprings Coil in Vehicle Suspension
Works exactly how I needed. The Ride is still very nice. There's about 350lbs with the weight of the box & rack. Suspension in the rear used to sag a bunch, even with a 2" suspension lift.
