Superlift’s 4-inch lift kit for the 2018 Wrangler JL Unlimited is the first lift kit on the market with replacement coil springs that are location specific. The all-new Shadow Series Shocks are a modern twin-tube gas charged, steel grey slim body shock. Through specialized testing, Superlift’s engineers determined that the same coil spring rate cannot be used side to side. These all-new dual rate coil springs and shocks will provide more extension for off-road use. To complement these JL coil springs and shocks, the kit also includes lower link arms, front track bar bracket, compression stop spacers, and extended sway bar links.
