Features:
Front lift coils for 2-Door Jeep JK, TJ/LJ, XJ and 4-Door Jeep JK Wranglers

Suspension components feature an abrasion-resistant black powder coat finish for maximum durability and corrosion resistance
Springs are designed to give the advertised amount of lift with use of aftermarket front bumpers & winches.

Notes:
2012+ JK’s lifted over 2″ will require exhaust spacers (5017), or a front aftermarket drive shaft to prevent interference with the exhaust
Springs retain the factory rake of the vehicle where the rear is higher than the front. Vehicle should sit level when loaded. Request one size shorter rear springs to level the vehicle out when unloaded

Lift heights listed for TJ/LJ and XJ are for models with the 4.0L engine. Expect approximately 0.5″-1″ more lift on 4 cylinder models.
