TeraFlex Alpine RT (Rogue-Trail) Suspension Systems build on the capable Alpine Cross-Trail CT Suspension Systems. Built with top-of-the-line components, this 3.5" lift is on of the most versatile and popular systems on the road today. The Alpine RT3 system IR Control Arms set the benchmark for today's long arm suspension systems. This kit includes adjustable IR Front and rear Track Bars and Front/Rear Track Bar Brackets for maximum adjustability that makes them a perfect mix of performance and driving comfort.
The Adjustable Alpine IR Long Control Arms tune caster angle, anti-squat geometry, and the tire position. Working with the Front and Rear Track Bar Brackets, the result is improved steering response, optimized roll center of the Jeep, and unsurpassed handling due to reduced body roll. Additionally, the Alpine IR Long Control Arms feature TeraFlex's new IR (Independent Rotation) Bushings. These are newly innovative bushings that remove bushing bind during compression of the suspension due to changes in the road. This results in a noticeable ride improvement as well as increased suspension articulation, minimized brake dive / acceleration squat! The IR Bushings also reduce bind during droop, for less bushing load during articulation.
TeraFlex suspension systems provide reduced noise, vibration, and harshness (NVH) compared to other kits. Available without shocks or with a choice of Falcon Shocks Series 3.3 performance shocks. We recommend Falcon shock absorbers for superior performance. Falcon shocks and TeraFlex coil springs have been designed to work together to improve both compression and rebound for optimal vehicle stability
Alpine Adjustable Long Control Arms balance front caster & pinion angles, as well as optimize rear angles for 0-4.5” lift kits
High-quality, maintenance-free IR Bushings allow unrestricted rotation during droop for less overall bind during articulation as well as improved ride quality
Adjustable Alpine IR Front and Rear Track Bars and Front (3.5”+) and Rear Track Bar Brackets improve steering response, center axles to optimize vehicle roll center, and reduce body roll for unsurpassed handling
TeraFlex SpeedBump Front & Falcon Progressive Rear Bump Stops provide progressive compression during high-speed suspension movement
