AEV's 2 Spacer Lift is a feature packed solution for Gladiator owners looking to add larger tires and improve ground clearance without having to replace their factory coil springs and shocks. The AEV 2? Spacer Lift includes unique front and rear polyurethane coil spacers with integrated isolators and locating tabs, front and rear bump stop extensions, extended length front and rear sway bar end links, front and rear shock extension brackets and a driveshaft carrier bearing spacer. AEV even goes one step further and takes care of the electronics by including a ProCal SNAP for painless speedometer recalibration! This 2? Spacer Lift has been engineered to integrate seamlessly with the Jeep Gladiator's OEM suspension system, minimizing the amount of parts you need to replace. Shock extension brackets allow the factory shocks to be used, which are often superior to many of the aftermarket shocks included with similar systems in this price range. New Front and Rear 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 will also recalibrate for axle gear ratio, transfer case gear ratio changes and TPMS threshold. AEV's 2? Spacer Lift provides a more aggressive appearance and without sacrificing the comfortable factory ride quality that drivers have come to appreciate in modern day Jeeps, like the Gladiator. Proudly made in the USA and backed by AEV's Lifetime Warranty.
