TeraFlex JL 4dr: 4.5” Alpine CT4 Long Arm Suspension System – No Shock Absorbers

TeraFlex Alpine CT (Cross-Trail) Suspension Systems build on our Sport ST (Street & Trail) Suspension Systems.

The 4.5” 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 & 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 balance front caster angle and pinion angles as well as optimize rear pinion angles, anti-squat geometry, and tire position on vehicles with 3-6” lifts. On higher lifts, Alpine Long Arm Brackets reposition frame-end control arm mounting points to restore near factory orientation to reduce bushing stress during extreme droop as well as shock load transferred through the control arms.

The HD Forged Adjustable Front Track Bar and Front and Rear Track Bar Brackets 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!

We recommend Falcon Performance Shocks. 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.
