The TeraFlex Prerunner Long Flexarm Suspension System begins where the Alpine CT4 Suspension System ends. The 4 Inch Prerunner kit builds on the 4 inch Alpine CT4 kit by adding all the components needed for a purpose-built speed system including extensive gusseting and brackets, heavy-duty suspension limit straps, and SpeedBump bump stops tuned for high-speed travel.
Engineered to handle high-speed off-road excursions, the 4 inch Prerunner Long Flexarm Suspension System is dependable and maintenance-free kit. With its focus on the speed aspect of off-road performance, the Prerunner kit features fully adjustable Alpine long flexarms to maximize wheel travel. Although we recommend 35 inch tires to reduce unnecessary rotational mass for quicker acceleration, the 4 inch lift height will accommodate up to 37 inch tires.
Suspension limit straps and SpeedBump bump stops maximize down travel safety to prevent any potential damage to drivetrain of suspension. In addition to reducing vibration and harshness, the additional gussets and reinforced bracketry beefs up areas prone to damage from high-speed off-road driving.
Falcon shocks and TeraFlex coil springs have been designed to work together to improve both compression and rebound for optimal vehicle stability. Does Not include shocks.
