Maximize the capability of your 2007-2018 Jeep Wrangler 2 Door with this 4-inch lift kit with long arm conversion 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. This 4-inch lift kit system improves on the factory 4-link with a redesigned 4-link long arm to improve articulation and offer better control throughout wheel travel.
Up front the lift kit includes new pivot mounts that are constructed from 1/4 inch thick steel and work with the new heavy duty lower flex arms and adjustable upper flex arms to optimize handling characteristics, 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 braided stainless steel brake lines, sway bar links, and front track bar relocation bracket and pitman arm to improve the steering and handling geometry.
In the rear the kit utilizes new pivot mounts designed to work with the new heavy duty lower flex arms and adjustable upper flex arms, Pro-Ride coil springs, sway bar drop brackets, and a rear frame mounted track bar relocation bracket to correct axle shift. 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.
Long Arm Conversion
Upgrading the standard control arms to a long arm adds strength, improves handling and takes offroad articulation to the next level. This upgrade consists of massive 1/4 inch steel frame mounted brackets to install the oversized upper and lower formed long arms. The arms are formed for maximum Tire clearance and allow the stock control arm tabs to remain on the vehicle. The upper arms are solid stock while the heavy wall tubular lower arms utilize oversized greaseable polyurethane bushings for superior road vibration isolation.
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.
