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 2.5” Alpine RT2 Short Arm Suspension System features Alpine IR Control Arms with our all-new IR (Independent Rotation) Bushings. These adjustable control arms and bushings team up to give your rig an unprecedented smooth and quiet ride both on- and off-road. Additionally, the included SpeedBump Front Bump Stops take the hard hits out of those unexpected trail surprises.

Adjustable Alpine IR Control Arms tune caster angle, anti-squat geometry, and tire position. The HD Forged Adjustable Front Track Bar works with the Front (3.5”+) and Rear Track Bar Brackets to improve steering response, optimize vehicle roll center, and reduce body roll for unsurpassed handling.

In addition to optimizing suspension geometry, adjustable Alpine IR Control Arms feature our all-new IR (Independent Rotation) Bushings. These innovative bushings remove bushing bind during suspension compression whether on the highway or the trail. This results in unrestricted droop as well as a noticeable ride improvement.

This results in increased suspension articulation along with superior ride quality and performance regardless of terrain. It also minimizes brake dive and acceleration squat. IR Bushings reduce bind during droop for less overall bushing load during articulation. TeraFlex suspension systems provide reduced noise, vibration, and harshness (NVH).

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

We recommend Falcon SP2 Mode Adjust Performance Shocks. Falcon shock absorbers and TeraFlex lift coil springs have been engineered together to improve both compression and rebound for optimal vehicle stability. Alpine RT Suspension Systems are offered with Falcon SP2 3.3 Fast Adjust Piggyback Shocks or without shock absorbers.
