The design of the Rusty’s 3” Coils for the Jeep JL was done in collaboration with the engineers and manufacturing team at Eibach.
With Rusty’s 40 plus years in the off-road and Jeep industry and Eibach’s experience in coil spring design and manufacturing, we came up with a coil spring that offers a quality ride with remarkable handling manners around town, on the highway, and even riding down an old, red clay pot hole road.
Not worried with being the first suspension kit for the new JL Wrangler, we wanted the best. Best in ride, handling, and articulation. We have done miles of testing from the desert and mountains of the West coast to the moss-covered mountain roads of Tennessee and North Carolina to the swamps of Florida, not to mention driving many highway miles in between. Thanks to all of this R&D, we are confident that we have the best coil spring design and know our customers will appreciate having the best coil spring that could be built.
