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.

Good product, but would not fit between coils on 4runner.

Sumo Super Springs is a first rate company. These coil spring helpers did not help. I measured the before and after ride height at max payload with and without a pair of these installed. Did not raise the rear of truck. If you insist on these, order a taller set than recommended. Or try 2 sets, though pretty pricey. I'd try alternative bump stops instead.

Works better than without, but I also have the bump stops replaced with the Sumosprings as well up front to work with unison with this one and Sumosprings in the rear as well.

So I measured my springs on the front of my Ford excursion 2003 6.0 I used the tool from the sumo spring website. Bought them on Amazon they were here pretty quick. Installed them pretty quick. Took a test drive around the neighborhood where I usually get thrown because the potholes and the roads are so bad. Noticeably different. Then I went to the other side of town later that day with my wife on the expressway and she noticed a huge difference as well. The vehicle drives a lot smoother and you don't notice the bumps as much.

Installed on a 2005 Tundra Double Cab with a leveling lift and an aftermarket heavy steel winch bumper. Getting the rings into the coil springs was difficult because the pre load from the leveling kit already installed. However, once installed the truck drove like it did prior to the bumper/winch install. I'm very pleased with the change. Absolutely buy if you have extra weight on the front end of your truck.

This product will help get a more comfortable ride. As you can see I used this product and the Sumosprings coil, which helped increase stability over cornering and protect the springs when carrying heavy loads. For reference, I included the Stock axel support and you will definitely see the difference between this and the Sumosprings.I would strongly recomended going into the Sumosprings store, and buy the correct solution for your vehicle. You input the model and make in their store and it gives you a sure fitment of their products to your vehicle.The instalation was relatively simple if you have the correct tools. Would recommend buying jack stands in order to support the weight of the vehicle, as normal jacks are not completely secure. Another important point is to use some sort of Loctite Threadlocker as it would eliminate the risk of the bolts coming lose due to vibrations.Would definitely recomend.

I can’t believe it. TRD Tundras are famous for having body roll while cornering and not a good ride for the stiffer TRD suspension. Well, after installing the Sumo Springs in the front the whole thing changed. Now it feels more stable while cornering, a smoother ride, more like flying on the highway, and even the engine sounds better. Waooo. I love my ride.

Gréât fit. Improved somehow the swing on my Kia Sorento 2018. Will probably buy another set for stiffer suspension.

these sumo super springs help to firm out the daily ride in my 2011 crown victoria interceptor. i have desired to make the daily ride as firm as possible without jolting my bones. the interceptor already comes firm from the factory but i wanted to create more predictability as the car performed. there is less corner lean and sway. i would suggest to those who have already upgraded their sway bars, shocks and springs that this would be the last step in mod's sequence in the suspension category the factory also offers a good product warranty.sincerely; randy goo; Texas
