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 4.5 Inch Alpine RT4 Long Arm Extended-Travel Suspension System excels on the highway, off-road, through the desert, or rock crawling! Bolt-on Alpine IR Long Arms & Brackets, HD Forged Adjustable Track Bars, and Track Bar Brackets allow full suspension adjustability, while the SpeedBumps smooth out unexpected trail bumps.

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 Inch 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.

Independent Rotation (IR) 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 Brackets improve steering response, center the axles to optimize vehicle roll center, and reduce body roll for unsurpassed handling.

Extended-Travel Suspension Systems include carefully selected components to safely provide 16 Inch of rear suspension travel.
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).
