SUPERLIFT Dual Rate Coil 4" Lift Kit (18-23 Jeep Wrangler JL Unlimited | 4 Door)

Superlift's all-new Dual Rate Coil Springs 4 inch lift kits for the 2018 Wrangler JL Unlimited is the first 4 inch lift kit on the market with replacement dual rate coil springs that are location specific. Through specialized testing, Superlift's engineers determined that the same coil spring rate cannot be used side to side. These new dual rate coil springs will provide excellent ride quality on-road while allowing more extension for off-road use. These new dual rate coils will also provide an even stance and long lasting durability.

Superlift's all new Dual Rate coil springs will give your Jeep Wrangler JL the ride, stance, and durability it desires. Each Dual rate coil features a transition of two rate ranges that give you that ultimate ride on pavement with the flexibility and durability of off-road performance.

To complement these new dual rate JLU coil springs, the kit also includes lower link arms, front track bar bracket, shock extension brackets, compression stop spacers, and extended sway bar links. The shock brackets allows the maximum amount of extension travel without drive shaft bind and the compression stop spacers prevent tire rub during full compression.
