3.5" 2018-2026 Jeep Wrangler JL 4WD (4 door) Alpine RT3 Outback Overland Short Arm Suspension Lift Kit by Teraflex

The Teraflex 1533301 Alpine Rogue Trail Suspension System for the Jeep Wrangler JL includes Alpine RT3 Long Arms and IR Short Control Arms, providing an unprecedented smooth and quiet ride on and off the road. Among Teraflex's most sought-after and adaptable systems, the 3.5" suspension is a favorite among enthusiasts. Equipped with HD Forged Adjustable Track Bars and Track Bar Brackets, this system offers maximum adjustability, striking the perfect balance between performance and comfort. The Adjustable Alpine IR Long Arms play a pivotal role in balancing front caster angle pinion angles and optimizing rear pinion angles, anti-squat geometry, and tire position for vehicles with 3–6" lifts. On higher lifts, the Long Arm Brackets strategically reposition frame-end control arm mounting points, restoring a near-factory orientation to mitigate bushing stress during extreme droop and absorb shock loads transferred through the Long Control Arms.

The Alpine IR Control Arms boast Independent Rotation (IR) Bushings, a revolutionary feature that eliminates bushing binds during full suspension travel. This innovation reduces the overall bushing load during articulation, ensuring unrestricted droop and delivering a noticeable improvement in ride quality, whether navigating highways or trails. Complemented by HD Forged Adjustable Track Bars and Track Bar Bracket(s), this system enhances steering response, centers the axles for optimal vehicle roll center, and minimizes body roll, delivering unparalleled handling. The result is an improved suspension geometry, relaxed control arm angles, and superior ride quality across diverse terrains. These systems restore front and rear roll axis angles, minimizing brake dive and acceleration squat. TeraFlex suspension systems are engineered to reduce noise, vibration, and harshness, providing a refined driving experience.
