The TeraFlex JK 3in Suspension Lift Kit delivers the ability to tackle some serious trails. 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!
