Description
Take your Jeep Wrangler Unlimited JL 4-Door to a new level with the JKS Manufacturing J-Kontrol 3.5in Suspension System. JKS based this lift kit on their proven J-Venture system, so it features the same front and rear dual-rate coil springs for superior consistency and handling. The included geometry correction brackets for premium ride quality. By lowering the frame side mounting point of the front control arms, JKS geometry correction brackets optimize driveline and suspension angles. The JKS Manufacturing J-Kontrol 3.5in Suspension System is available with either JSPEC Custom Valve Gas Shocks or Fox 2.0 Performance Series Shocks.

Many states have laws that limit the maximum height of a lifted vehicle. Never exceed the legal height limit.
