The Rancho rear coil spring kit for 2018 Jeep Wrangler JKU (4-door) is specified to raise the rear about 1.75 inches to maintain stance and free up space for larger tires without fender modification. These progressive-rate springs are shot-peened, heat-treated high-strength steel with a corrosion-resistant finish, include two rear springs and installation hardware, and are tuned to preserve ride comfort under load while offering improved capability and a limited one-year warranty.
