BDS SUSPENSION | 4.5" Lift Kit | 12-18 Jeep Wrangler JK 4 Door | 1405FPE / 1405FS / 1405H / 1406FS / 1406H

Description
Take your 2012-2018 Jeep Wrangler JK 4 Door to the next level and improve the ride with this 4.5-inch lift kit from BDS Suspension. Designed to strengthen stance, this kit includes everything necessary to set your truck up right with clearance for up to 37" tires.
Up front, the lift kit includes 4" Pro-Ride coil springs, capable of full coil bind, and 3" bump stop extensions to control compression travel while increasing wheel travel. Also included are brake line brackets, sway bar links, a front track bar relocation bracket, and a pitman arm, all designed to improve steering and handling geometry. The front suspension in this 4-inch lift kit is finished off with fixed-length lower control arms featuring OE-grade rubber bushings, which reposition 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" lift kit with your choice of specially tuned NX2 nitro series gas shocks or FOX 2.0 IFP 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 is supplied to provide the correct lift height and a smooth, predictable ride across various terrains. Manufactured from high-tensile steel, our direct OE replacement coil springs are engineered with properly sized wire diameters. 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, paired with a heavy-duty track bar drop bracket to keep them in phase throughout suspension travel while recentering the front axle.
