JL 4dr: 2.5” Alpine RT2 Outback Overland Short Arm Suspension System – No Shocks
The TeraFlex 2.5” Alpine RT2 Outback Overland Short Arm Suspension System is built to handle expedition-style overland travel such as the Canning Stock Route in Australia, the Silk Road in China, or your favorite trail in the U.S.
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 2.5” Alpine RT2 Outback Overland Short Arm Suspension System is built to handle expedition-style overland travel such as the Canning Stock Route, the Silk Road, or your favorite trail. The Outback Overland builds on the standard Alpine RT2 by adding heavy-rate Outback Lift Coil Springs that maintain lift height when loaded. The Outback Overland handles the toughest trails! Adjustable Alpine IR Short Arms balance front caster angle and pinion angles as well as optimize rear pinion angles, anti-squat geometry, and tire position on vehicles with 0–4.5” lifts. Alpine IR Control Arms feature our 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 Lower and/or Rear Lower Track Bar Bracket(s) 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.
