Combined with the HD Adjustable Front and Rear Track Bars, the Alpine RT4 provides full suspension adjustability both on- and off-road! Alpine Long Arm Brackets reposition frame-end control arm mounting points to restore near factory orientation. The HD Forged Adjustable Front and Rear (4”+) Track Bars and Rear Track Bar Bracket improve steering response, center the axles to optimize vehicle roll center, and reduce body roll to for unsurpassed handling. In addition to optimizing suspension geometry, adjustable Alpine IR Long Control Arms and Alpine IR Control Arms feature our all-new IR (Independent Rotation) Bushings. These innovative bushings remove bushing bind during full suspension travel whether on the highway or the trail. This results in unrestricted droop as well as a noticeable ride improvement. This results in improved suspension geometry and relaxed control arm angles for a superior ride quality and performance regardless of terrain. These systems restore front and rear roll axis angles to minimize brake dive and acceleration squat. IR Bushings reduce bind during droop for less overall bushing load during articulation.
