Superlift’s all-new 4 inch lift kits for the 2018 and newer Wrangler, including Rubicon, feature 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 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.
Each dual rate coil features a transition of two rate ranges that give you the ultimate ride on pavement with the flexibility and durability of off-road performance.
To complement these new dual rate JL coil springs, the kit also includes lower link arms, front track bar bracket, FOX 2.0 Reservoir Shocks, compression stop spacers, and extended sway bar links.
The Fox Shocks allow the maximum amount of extension travel without drive shaft bind, and the compression stop spacers prevent tire rub during full compression.
