Manufactured by Teraflex. The TeraFlex JK 4� Suspension System delivers everything 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, all lower and upper adjustable flexarms, front adjustable track bar, 9550 shock absorbers, front sway bar disconnects, rear sway bar links, rear track bar bracket, bump stops 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, or use stock wheels with TeraFlex Offset Wheel Adapters (#1055000 - 2 sets). Fits all JK Wrangler models including Rubicon and Unlimited. Note: 2012+ JKs require exhaust spacers (#2610000) or other exhaust modification for proper driveshaft clearance. Driveshaft modifications are highly recommended with this lift kit.
