TeraFlex Alpine CT (Cross-Trail) Suspension Systems build on our Sport ST (Street & Trail) Suspension Systems. The TeraFlex 6in Alpine CT6 Long Arm Suspension System excels on the highway, off-road, through the desert, or rock crawling! The Alpine CT6 includes our HD Drag Link Flip Kit w/ Front Track Bar Drop Bracket & Frame Brace Kit to correct steering geometry, eliminate front end shimmy, and reinforce the frame. With its 6in lift coil springs and the ability to run a 38in tire with stock fender flares, the Alpine CT6 can conquer the toughest trails! Our 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 3-6in 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 Alpine Long Control Arms. The HD Forged Adjustable Front and Rear (4in+) Track Bars and Rear Track Bar Bracket improve steering response, center the axles to 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! 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 Falcon Series 3.3 Fast Adjust Piggyback Shocks or without shock absorbers.
