JL 4dr: 4.5 Alpine RT4 Long Arm Suspension System - No Shocks

The TeraFlex Alpine RT (Rogue Trail) Suspension System is a high-performance long arm suspension system designed for the Jeep Wrangler JL (4-door). It excels on various terrains, including highways, off-road trails, deserts, and during rock crawling. The system features bolt-on Alpine IR Long Arms & Brackets, heavy-duty forged adjustable track bars, and track bar brackets for full suspension adjustability. SpeedBumps are included to smooth out unexpected bumps. This system aims to improve suspension geometry, optimize front caster and pinion angles, rear pinion angles, anti-squat geometry, and tire position for vehicles with 3-6 inch lifts. It also restores front and rear roll axis angles to minimize brake dive and acceleration squat. The Alpine IR Control Arms utilize Independent Rotation (IR) Bushings to reduce bushing bind and improve ride quality. The system is designed to reduce noise, vibration, and harshness (NVH) and comes with a lifetime warranty. Shocks are not included and Falcon Performance Shocks are recommended (sold separately).
