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 TeraFlex 4 Inch Alpine RT4 Long Arm Suspension System is developed for the off-roader craving trails and rocks as well as highway control in a no-compromise package. With its Alpine IR Long Control Arms & Brackets, this suspension system provides a completely new driving experience. Combined with the Front and Rear HD Adjustable Track Bars, the Alpine RT4 provides full suspension adjustability both on- and off-road!

Adjustable Alpine IR Long Control Arms balance front caster and pinion angles as well as optimize rear pinion angles, anti-squat geometry, and tire position on vehicles with 3-6 Inch 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.

HD Forged Adjustable Track Bar(s) and Rear Track Bar Axle Bracket improve steering response, center the axles to optimize vehicle roll center, and reduce body roll for unsurpassed handling.

This results in improved suspension geometry for superior ride quality and performance regardless of terrain. TeraFlex suspension systems provide reduced noise, vibration, and harshness (NVH).

Alpine RT Suspension Systems are for the Jeeper who wants it all!
