Your cart is empty.Coil SumoSprings improve the load leveling ability of original equipment front and rear coil springs. Manufactured from micro-cellular urethane, the material’s progressive spring rate with superior damping properties creates a cushion effect, enhancing capacity and ride comfort. They install by simply being slid between the turns of the coil spring.

I have a swing hitch with a cargo box mounted on my Sienna. The SumoSprings were installed. No more sagging! Love these.They were not as easy to install as depicted in the video. Really should use a lift.

Installed set CSS-1195 on my 2014 Toyota Sienna on the rear springs. We frequently load this van and the trailer hitch with bikes or coolers, etc. The rear is easily .5" - .75" higher and I already notice a huge improvement in stability in the rear, rear is stiffer.These truly do install with no tools, but they do not slip on easily. It took me about a half hour on each side struggling to get these to snap on, they are suck a tight fit. You really need to be generous with the soapy water to get these on, I went through about a cup of soapy water on each one from a spray bottle.

Takes A little over an hour to install both, and if you've never installed them before. Fit snug on the struts. They are held in place with zip ties.

A great addition to the suspension of my 2023 ram Pro master 1500. Gets rid of a lot of the front end bounce that was occurring going over speed bumps and potholes. Drive feels much more stable.

Had these inserted on the front springs by the dealer who did my oil change. Since they had it on the lift they said they were easy to install so they didn’t charge me. I had done the back a year ago myself. Can feel the difference over ruff roads and corners. Very stable for a an extended roof van. Highly recommend

These improved my 2017 Dodge Ram 2500 based Class B RV Ride (mtn road side-sway) and front ground clearance (adds about 1/2"). Although feels more front bounce and back-kick over bumps. In my opinion, they are worth it just for the added clearance for the expensive RV stuff under the chassis, the ride effect depends on the roads one drives and folks personal feel. Using these injunction with the Sumo Rear Bump-stop. Installed these by myself in less than a hour, but took a lot of hand strength and several tries to get engagement between the coils on passenger side, good instructions. Not sure how long these will last, all polymer in high load area, but they do have a limited lifetime warranty. -1 star for not as good as the Rear sumos for clearance and installation.

Since these are apparently the only helper springs available for the Honda Ridgeline, I had to give them a try. Dang they are some expensive pieces of rubber (okay, space age MCU, but still). I bought a pair for the rear to help with the towing and heavy loads I typically carry.They take a bit of work to install. Definitely take the wheel off, and don't be stingy with the soapy water. The first one took at least an hour of struggle because the spring wasn't slippery enough, but the second one went on in 15 minutes. Also look up the Youtube video on installing, they guy makes it look really easy but it helps to see his technique. I used various long ratchet handles and pieces of wood to lever off the chassis, to push the lip over the coil.The end result is a ride that is much more stable, and the ride is easily 1" higher which I don't mind on this truck. I haven't tried it yet with a load but it definitely feels like it will be sagging less. There is also less squat on acceleration.I'm tempted to put a pair on the front to level it out.
