The AEV 2-inch Spacer Lift Kit for 2018+ Jeep Wrangler JL includes unique front and rear polyurethane coil spacers with integrated isolators and locating tabs, front and rear bump stop extensions, extended length front sway bar end links, corrosion-resistant e-coated and powder coated front and rear shock extension brackets. AEV even goes one step further and takes care of the electronics, this kit includes AEV's new ProCal SNAP for painless speedometer recalibration and more. This 2-inch Spacer Lift Kit has been engineered to integrate seamlessly with the Jeep Wrangler JL. It retains the quality and tuning of the JL's factory shock absorbers, which are often superior to many of the aftermarket shocks sometimes included with similar systems in this price range. The shock extension brackets allow the factory shocks to be used without limiting wheel travel and the front sway bar end links have been extended to ensure bind-free functionality. AEV's ProCal SNAP is a simple, electronic recalibration module that plugs into your vehicle's OBDII diagnostic port. It utilizes the stereo's audio equalizer to input the numerical values for your new tire size- saving you time and money by not having to make a trip to the dealership for speedometer recalibration. The ProCal SNAP also has the ability to recalibrate for axle gear ratio as well as transfer case gear ratio changes. AEV's 2-inch Spacer Lift Kit for the 2018+ Jeep Wrangler JL provides a more aggressive appearance and without sacrificing the comfortable factory ride quality that drivers have come to appreciate in modern day Jeeps, especially the JL Wrangler.
