The 3.5” suspension is one of our most popular and versatile systems. With its Alpine IR Long Arms & Brackets, the new Alpine RT3 Long Arm Suspension System provides a completely new driving experience. This kit includes HD Forged Adjustable Track Bars and Track Bar Brackets for maximum adjustability making them the perfect mix of performance and comfort.
Adjustable Alpine IR Long Arms balance front caster angle and pinion angles as well as optimize rear pinion angles, anti-squat geometry, and tire position on vehicles with 3–6” lifts. On higher lifts, 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 Long Control Arms.
Alpine IR Control Arms feature our Independent Rotation (IR) Bushings. These innovative bushings remove bushing bind during full suspension travel for less overall bushing load during articulation resulting in unrestricted droop as well as a noticeable ride improvement whether on the highway or the trail.
HD Forged Adjustable Track Bars and Track Bar Bracket(s) improve steering response, center the axles to optimize vehicle roll center, and reduce body roll for unsurpassed handling.
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. TeraFlex suspension systems provide reduced noise, vibration, and harshness (NVH).
Alpine RT Suspension Systems are for the Jeeper who wants it all!
