JL 4dr: 3.5 Alpine RT3 Long Arm Suspension System - No Shocks

The TeraFlex 3.5" Alpine RT3 Long Arm Suspension System offers a new driving experience with Alpine IR Long Arms & Brackets. It provides maximum adjustability, including HD Forged Adjustable Track Bars and Track Bar Brackets, balancing performance and comfort. The adjustable Alpine IR Long Arms optimize front caster/pinion angles, rear pinion angles, anti-squat geometry, and tire position for vehicles with 3-6 inch lifts. Long Arm Brackets reposition frame-end control arm mounting points to restore near factory orientation, reducing bushing stress during extreme droop and shock load. Alpine IR Control Arms feature Independent Rotation (IR) Bushings to remove bushing bind during full suspension travel, reducing overall bushing load during articulation for unrestricted droop and improved ride quality on and off-road. The system enhances steering response, centers axles to optimize vehicle roll center, and reduces body roll for superior handling. It also restores front and rear roll axis angles to minimize brake dive and acceleration squat. TeraFlex suspension systems reduce noise, vibration, and harshness (NVH). This kit does NOT include shocks; recommended Falcon Performance Shocks are sold separately.
