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

Falcon SP2 3.3 Fast Adjust Piggyback Shocks:

• The Falcon SP2 3.3 Fast Adjust Piggyback Shocks utilize a three-position knob to change the ride and dampening settings from soft to medium to firm while incorporating an 8-point Micro-Adjust Dial to precisely tune your handle in the medium setting for complete 10-point adjustment control easily accessed and adjusted at the top of the shock.

Falcon SP2 3.1 Piggyback Shocks:

• The Falcon SP2 3.1 Piggyback Shocks deliver improved ride quality, comfort, and stability, while the increased compression of the piggyback reservoir provides agile off-road handling while being optimized for on-road comfort. Consider the Falcon 3.1 if you want all-out performance without the 10-point adjustability of the 3.3 series.

Falcon SP2 2.1 Monotube Shocks:

• The Falcon SP2 2.1 Monotube Shocks deliver increased stability and ride quality over stock and other aftermarket shocks and are the perfect choice for those who are looking for all-around performance in a compact and affordable package for both on and off-road performance.

What does the SP2 mean in the Falcon Shock series?

• Choose between Soft and Performance modes during installation; Tunes both compression and rebound
• Soft mode allows a partial bypass of the main piston for a softer ride
• During aggressive driving, soft mode retains performance tuning for optimal handling
• Soft mode recommended for rough terrain/surfaces and cold weather
• Performance mode recommended for max on- and off-road handling, stability, and control
• SP2 setting selected by rotating the shock shaft 360 degrees while being installed
