On a lifted 2012 and later JK the front driveshaft can touch the exhaust crossover pipe when the suspension droops. That contact damages the pipe or the shaft.
The TeraFlex exhaust spacers install between the header flanges and the crossover pipe flanges and move the crossover pipe rearward for driveshaft clearance. They are required on 2012-2018 JK models with 2.5 in or more of lift.
