Jeep Wrangler JK 4-Door 2007-2018, TeraFlex 4in Coil Spring Base Lift Kit with Front Track Bar, No Shocks

A 4in lift on a 4-door JK pushes the front axle sideways, and a base kit without a track bar leaves it off center. The TeraFlex 4in Coil Spring Lift Kit with Track Bar adds an HD forged adjustable front track bar to 4in springs, spacers, bump stop extensions, strike pads and sway bar parts. Shocks are not included, and TeraFlex recommends Falcon Performance Shocks or its 9550 VSS shocks. Longer preset or adjustable control arms are still required to correct geometry, and an adjustable rear track bar is recommended. Install the kit and the Unlimited clears 37in tires.
