TeraFlex 3.5" Alpine RT3 Short Arm Suspension System No Shocks Jeep Wrangler JL 2dr 2018-2024 - 1533200
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 3.5" suspension is one of our most popular and versatile systems. The Alpine RT3 Short Arm Suspension System's Alpine IR Short Control Arms sets the benchmark for short arm suspension systems. This kit includes an HD Forged Adjustable Front Track Bar and Front and Rear Track Bar Brackets for maximum adjustability making them the perfect mix of performance and comfort. Adjustable Alpine IR Short Control 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. The HD Forged Adjustable Front Track Bar and Rear Track Bar Bracket improve steering response, center the axlesto optimize vehicle roll center, and reduce body roll for unsurpassed handling. Additionally, Alpine IR Control Arms feature our all-new IR (Independent Rotation) 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. 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! We recommend Falcon Performance Shocks. Alpine RT Suspension Systems are offered with select Falcon SP2 Mode Adjust Piggyback Shocks including: 3.5 aDAPT e-Adjust, 3.3 Fast Adjust, or without shock absorbers. Other Falcon shocks are available separately.
