Overview

This 4-inch lift kit from BDS Suspension is designed for the 2007–2011 Jeep Wrangler JK 2-Door, improving stance and providing clearance for up to 37-inch tires. Up front, the kit includes 4-inch Pro-Ride coil springs capable of full coil bind and 3-inch 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 forged drop pitman arm to improve steering and handling geometry. Fixed-length lower control arms with OE-grade rubber bushings re-position the front axle for proper alignment.
