TeraFlex Alpine CT (Cross-Trail) Suspension Systems begin where our Sport S/T (Street/Trail) Suspension Systems end.

The granddaddy of all our kits, the TeraFlex Alpine CT6 Suspension System is engineered to excel whether driving on road or on the trail, through the desert, or rock crawling! The 6" lift Alpine CT6 builds on the 4" lift Alpine CT4 by adding a heavy-duty drag link flip kit and heavy-duty frame brace kit to correct steering geometry, eliminate front end shimmy, and reinforce the frame.

Our fully adjustable Alpine flexarms have been engineered to allow tuning of the pinion and caster angles, anti-squat geometry, and tire position as well as optimize front and rear roll centers. The heavy-duty adjustable front track bar and rear track bar bracket eliminate side-to-side movement. Alpine flexarms feature dependable and maintenance-free bushings. The gusseted and reinforced bracketry reduces noise, vibration, and harshness (NVH) compared to other longarm kits.

All of this adds up to provide full suspension articulation and flex off-road along with superior ride quality and performance on road as well as minimal brake dive and squat under acceleration to better put the power down on any surface.

Falcon shocks and TeraFlex coil springs have been designed to work together to improve both compression and rebound for optimal vehicle stability.
