TeraFlex Alpine RT (Rogue Trail) Suspension Systems build on our already capable Alpine CT (Cross-Trail) Suspension Systems. These systems include all our top-of-the-line components.
The 3.5” suspension is one of our most popular and versatile systems. With its Alpine IR Long Control Arms & Brackets, the new Alpine RT3 Long Arm Suspension System provides a completely new driving experience. This kit includes Front and Rear HD Forged Adjustable Track Bars and Front and Rear Track Bar Axle Brackets for maximum adjustability making them the perfect mix of performance and comfort.
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 vehicles with 3-6” lifts. On higher 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 long control arms.
Alpine IR Control Arms feature our all-new 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.
Front and Rear HD Forged Adjustable Track Bars, and Front and Rear Track Bar Axle Brackets 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!
Does NOT include shocks. We recommend Falcon Performance Shocks. Falcon shock absorbers and TeraFlex lift coil springs have been engineered together to improve both compression and rebound for optimal vehicle stability. Falcon shock absorbers and steering stabilizers available separately.
