Teraflex 3.5” Alpine CT3 Short Arm Suspension System
TeraFlex Alpine CT (Cross-Trail) Suspension Systems build on our Sport ST (Street & Trail) Suspension Systems.
A 3.5” suspension system opens up a new world of tire sizes and off-road possibilities. If you have that “do it all” attitude, one of our 3.5” Alpine CT3 Suspension Systems will make it happen. The Alpine CT3 Short Arm features our Alpine Short Control Arms as well as a Front HD Forged Adjustable Track Bar, and Front and Rear Track Bar Axle Brackets for maximum tunability and flawless performance for years to come.
Adjustable Alpine Short Control Arms balance front caster and pinion angles as well as optimize rear pinion angles, anti-squat geometry, and tire position on vehicles with 0-4.5” lifts.
The Front HD Forged Adjustable Track Bar and Track Bar Axle Bracket(s) improve steering response, center the axles to optimize vehicle roll center, and reduce body roll for unsurpassed handling.
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 CT Suspension Systems are engineered for hardcore Jeeping without sacrificing weekday ride comfort!
Does NOT include shocks. We recommend Falcon Performance Shocks. Falcon shock absorbers and TeraFlex lift coil springs have been engineered together to improve both compression and rebound for optimal vehicle stability. Falcon shock absorbers and steering stabilizers available separately.
