The 2.5” Alpine RT2 Short Arm Suspension System features Alpine IR Short 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 front SpeedBump Bump Stops take the hard hits out of those unexpected trail surprises.
Our long and short adjustable Alpine IR Control Arms balance front caster angle and pinion angles as well as optimize rear pinion angles, anti-squat geometry, and tire position. The adjustable Alpine IR Front Track Bar and Front Track Bar Bracket (3.5”+) 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. IR Bushings reduce bind during droop for less overall bushing load during articulation. TeraFlex suspension systems provide reduced noise, vibration, and harshness (NVH).
