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" 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.
