They install by simply being slid between the turns of the coil spring. Every SumoSpring is handmade with care, making each one unique with its own natural characteristics, such as slight color variations and surface bubbles—proof of the craftsmanship that goes into every piece.

Springs showed up within 3 days not 2 weeks as expected. Nicely done! Installation took me about 2 hours for front and rear. Rears we’re easy. Fronts [CSS-1195] easy as well once I had the vehicle high enough. Make sure the tire is just off the ground for best results. We took the van on a 300 mile road trip the next week. Trip included driving in heavy cross winds (15-25 mph) and one encounter with a dust devil at 70 mph. Winds were noticeable however the handling was always solid. My wife does most of the driving due to her propensity for car sickness. She loves driving the van and was very happy with the springs performance. I would recommend this product to anyone wanting a bit more firmness in ride and handling. Well worth the money especially since DIY is very easy.

It Works. Ride improved. I was skeptical. Cost is Worth it. Noticed softer, but firm cushioned ride immediately.

WOW, just WOW!! I installed these on my Winnebago Solis Pocket and I get believe the difference in handling this has given the van. The rig feels very solid going into corners, over bumps, and sudden steering correction during normal driving. Sumo springs customer services is also absolutely too notch. I had timely responses and excellent communication. Fantastic purchase, fantastic company.

Really satisfied by the quality and the design of your product. Complet installation as been done in 1 hours and a half without using any specialized tools.
And the results is amazing. I drove a truck loaded with tools for a service company. This is exactly what my truck needed.
Thanks again for your hard work and for your great service.

Bought a pair of the CSS-1125 for my ’07 Impala SS as I tow a 25ft Airstream and they really help with sway. Now I just ordered a pair of the CSS-1195 for the front to match the rear. The ride is firm but not stiff. I find you still get the responsive (FE3 suspension) and comfortable ride; towing or not.
Made a big difference.
Cheers, Paul

Bought a pair of the CSS-1195 for my 2018 Toyota Sienna XLS AWD. Very easy to install the SumoSpring for the front suspension. Noticeable improvements of the body roll reduction at the corners, which leads to better handlings and driving experience. Very satisfied with the purchase
