Get the cushioning of SumoSprings for your coils. These wedge-shaped springs fit between the individual coils in each spring of your Ram ProMaster 2500's front suspension for better load support and a more comfortable ride. Great for trucks with snowplows.
Features:
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.

worked fine
Works Great
Put them on my F-150 and It's great for towing my 36' rv
Easy to install, didn't affect ride, made carrying my plow much better.
Excellent, to help mitigate propoising while towing.
Run them at all 4 corners on 2018 Expedition w/tow pkg.
Would not to w without them.
This Spring rubber did what it was designed to do and stayed in place.It also was a snap to install
clear instructions, easy install and they work great.
Purchased these to take a little load of my strut assembly because of a heavy winch bumper and winch. Product works well....
Have worked great on my Expedition towing a 25 ft travel trailer over 9000 miles last summer.
I used these to stiffen the suspension on a ‘21 Sedona. They work great and are easy to install.
Product came as described, fast shipping, works great. Bought it to stiffen front end because of snowplow. Thanks
Helps with trailer squat tremendously - Installation was very difficult to expand strings wide enough
They don't seem to be the right ones for my silverado 1500 4x4. Too much play between spring even without lifting vehical?
These springs did not really change the unloaded ride quality. They also added about 1/2 of lift to the front of my truck. I wasn't expecting that, but it worked out for me. I installed a 2 inch front leveling kit about a year ago and I wished I went with a 2.5 leveling kit.
These reduced nosedive hard braking when loaded significantly as well as leveling the front end when towing on my 4runner
As advertised, simple install and dampens sway in my classB motorhome.
Installed on 2006 F 150 to prevent front sag when using front hitch mounted cooler rack for surf fishing. Easy install. Start at bottom of spring where there is more room to work. Loosely install tie wraps then rotate sumo to top of spring between 2 and 3 coil, then tighten tie wraps. Haven't had chance to evaluate performance with cooler rack.
