TeraFlex Alpine CT (Cross-Trail) Suspension Systems build on our Sport ST (Street and Trail) Suspension Systems. The 4.5 inch Alpine CT4 Long Arm Suspension System was engineered for the enthusiast who demands an off-road capable suspension with maximum adjustability, flex, durability, and quiet performance.
This all-inclusive system includes everything from the TeraFlex exclusive brake line anchor brackets to our industry leading adjustable Alpine Long Control Arms and Brackets. The Alpine CT4 is designed to flex and droop over boulders and fly across flats like nothing you have ever experienced. And like all TeraFlex lifts, the highway manners of the CT4 are legendary.
Adjustable Alpine Long Control Arms tune caster angle, anti-squat geometry, and tire position. On higher lifts, Alpine Long Control Arms retain near factory orientation to reduce bushing stress during extreme droop as well as reduces shock load transferred through the control arms. The adjustable Alpine IR Front Track Bar and Front (3.5 inch and up) and Rear Track Bar Brackets improve steering response, optimize vehicle roll center, and reduce body roll to 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 SP2 Mode Adjust Performance Shocks. Falcon shock absorbers and TeraFlex lift coil springs have been engineered together to improve both compression and rebound for optimal vehicle stability. Alpine CT Suspension Systems are offered with a choice of Falcon SP2 3.3 Fast Adjust Piggyback Shocks, Falcon SP2 3.1 Piggyback Shocks, or without shock absorbers.
