JSPEC Jeep Lift Kits & Suspensions Systems | J-Rated

More than just typical lift kits, the six JKS JSPEC Suspension System types below are engineered to match your Jeep's specific handling and performance needs -- on and off-road.

All suspension packages are available in multiple lift heights to accommodate larger tires and increase ground clearance. Common features include high-performance coil springs, custom-tuned JSPEC and FOX shocks, sway bar quick disconnects, adjustable track bars, and more. From there, system-specific features are engineered to match your preferred terrain, budget, and your Jeep’s specs. Before you go buying any old lift kit, ask yourself: Are you J-Rated?
