4 inch Lift Kit – Jeep Wrangler JL Unlimited 2018 and newer, including the Rubicon featuring Dual Rate Coils with Shock Extensions, Shadow Shocks, Fox Shocks, or King Shocks.
The first 2.5 inch lift kit on the market with replacement dual rate coil springs that are location specific is Superlift’s all-new Dual Rate Coil Springs for the 2018 and newer Wrangler JL Unlimited.
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 allow more extension for off-road use while providing excellent ride quality on-road.
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 JLU 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 shock extension brackets or Fox Shocks, compression stop spacers, and extended sway bar links.
The Fox Shocks or shock brackets allow the maximum amount of extension travel without drive shaft bind, and the compression stop spacers prevent tire rub during full compression.
