Jeep Wrangler JK 4-Door 2007-2018, TeraFlex 4in Coil Spring Base Lift Kit with Front Track Bar and 9550 VSS Twin-Tube Shocks

A 4in lift on a 4-door JK pushes the front axle sideways and puts the suspension geometry out of line. The TeraFlex 4in Coil Spring Base Lift Kit with Front Track Bar adds an HD forged adjustable front track bar to 4in springs, spacers, bump stop extensions, strike pads, sway bar parts and stainless braided brake lines. TeraFlex 9550 VSS twin-tube shocks are included. This is a base kit, so adjustable short or long Alpine control arms and a rear HD forged adjustable track bar are required or recommended to finish the geometry. Install it and the Unlimited clears 37in tires.
