TRU specialist notes
From the Trucks R Us fitment and install team, beyond the manufacturer's information.
- Plan for a professional wheel alignment after installing any lift or leveling kit.
- Going to bigger tires as well? Speedometer recalibration may be needed, and some tire and wheel combinations need trimming. Check the recommended wheels and tires, or ask us before you order.

Overview
Maximize the capability of your 2007-2018 Jeep Wrangler 4 Door Rubicon with this 4.5-inch lift kit featuring a 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" tires. This 4-inch lift kit system enhances the factory 4-link by introducing a redesigned 4-link long arm, which improves articulation and offers better control throughout wheel travel.
Up front, the lift kit includes new pivot mounts that are constructed from 1/4" thick steel and work with the latest heavy-duty lower flex arms and adjustable upper flex arms to optimize handling characteristics, 4" Pro-Ride coil springs capable of full coil bind, and 3" bump stop extensions to control the compression travel, but increase wheel travel. Also included are braided stainless steel brake lines, sway bar links, a front track bar relocation bracket, and a pitman arm, all designed to improve steering and handling geometry.
In the rear, the kit utilizes new pivot mounts designed to work with the latest 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" 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.
Long Arm Conversion
Upgrading the standard control arms to long arms adds strength, improves handling, and takes off-road articulation to the next level. This upgrade consists of massive 1/4" steel frame-mounted brackets to install the oversized upper and lower formed long arms. The arms are designed for maximum tire clearance, allowing the stock control arm tabs to remain in place on the vehicle. The upper arms are made of 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 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 diameter. This results in maximum reliability without premature coil bind.
