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. 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.

My 2017 Hyundai SF is a great SUV with the only complaint I’ve had is the rear suspension seems underside and appears to easily bottom out. I had the Coil SumoSprings installed and they made a noticeable improvement when pulling a 21’ boat

Took the rock out of this beast

Super easy to install. I can already feel the difference.

Just did a 900 mile ski trip from South Carolina to West Virginia. Installed these on the rear of our 2017 Dodge Journey a week prior to leaving. The back of our car was packed to the roof with gear, food, supplies and skis on the roof rack. With three of us in the car these coil Sumosprings helped out tremendously with rear sag. Added unbelievable stabilily, control and much less body roll driving in the curvy mountain roads. I’ve ordered them for the front of our Journey as I believe the set up will be complete with the front end ones installed. Very happy, but a little tough to install as I’m a mechanic. Cleaning the coil springs and using dish soap on the coil Sumosprings is a must! Found it was best to install with small pry bars and dull edged tire spoons as it will take a lot of force to slip these on in between the coils.

The coil inserts seem to help with load stabilization, cornering, and rough road shock absorption.

Purchased to improve the towing capability and improve the ride when my 8400# travel trailer is connected via equalizer hitch. Summo springs were my only solution due to Ford Factory CCD strut suspension.
