Take your 2012-2018 Jeep Wrangler JK 2 Door to the next level and improve the ride with this 4-inch lift kit from BDS Suspension. Designed to improve stance this kit includes everything necessary to set your truck up right with clearance for up to 37 inch Tires.
Up front the lift kit includes 4 inch Pro-Ride coil springs capable of full coil bind and 3 inch bump stop extensions to control the compression travel, but increase wheel travel. Also included are brake line brackets, sway bar links, and front track bar relocation bracket and pitman arm to improve the steering and handling geometry. The front suspension in this 4-inch lift kit is finished off with fixed length lower control arms with OE grade rubber bushings that re-position the front axle for proper alignment.
In the rear the kit utilizes Pro-Ride coil springs, sway bar drop brackets, and a rear frame mounted track bar relocation bracket to correct axle shift. For proper rear axle position and pinion angle this kit includes fixed length rear lower control arms and adjustable rear upper arms. Round out this 4 inch lift kit with your choice of specially tuned NX2 nitro series gas shocks or FOX 2.0 Internal Floating Piston performance series gas shocks to offer improved damper performance.
Pro-Ride Coil Springs
A pair of full-length, gas-specific, progressive rate Pro-Ride coil springs are supplied to provide the correct lift height and smooth, predictable ride across various terrains. Manufactured from high tensile steel, our direct OE replacement coil springs are engineered with properly sized wire diameter. This results in maximum reliability without premature coil bind.
Steering Correction
To optimize steering geometry once lifted, a forged drop pitman arm is used to minimize the steering angle and pair it with a heavy duty track bar drop bracket to keep them in phase through suspension travel while recentering the front axle.
