The TeraFlex JK 4” Basic Suspension Lift Kit delivers the performance that you need to conquer the most extreme trails and conditions. Drivability and performance are the most important factors that are engineered and built into every TeraFlex lift kit. Properly developed suspension geometry, roll center, and load tuning ensure that all factory stability controls remain functional and within the parameters that Jeep originally engineered into the vehicle. TeraFlex kits drive straight and will crawl anything, getting you there and back! This system includes 4” lift coil springs, front swaybar disconnects, rear swaybar links, rear trackbar bracket, bumpstops and all necessary hardware. This kit will allow you to run up to a 37” tire (aftermarket wheels with 4.5” backspacing or less are required). Fits all right hand drive JK Wrangler models including Rubicon. Note: This is not an all inclusive kit. Additional components are necessary for proper alignement and drivability such as a front adjustable trackbar and adjustable control arms. Driveshaft modifications are highly recommended with this suspension system. 2012+ JKs require exhaust spacers (#2610000) or other exhaust modification for proper driveshaft clearance.
