The Alpine RT6 is the pinnacle of JK suspension systems! Adjustable Alpine IR Long Control Arms balance front caster angle and pinion angles as well as optimize rear pinion angles, anti-squat geometry, and tire position. On 4-6” lifts, Alpine Long Arm Brackets reposition frame-end control arm mounting points to restore near factory orientation to reduce bushing stress during extreme droop as well as shock load transferred through the Alpine IR Long Control Arms. 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.
