Exhaust spacers are needed for all 2012 and up Jeep JK?s using
suspension kits with 3 inch or more of lift.. The spacers are installed between the driver and
passenger head pipe flanges and the flanges of the exhaust cross pipe which moves the exhaust cross pipe rearward. This prevents contact between the front driveshaft and the exhaust cross pipe during suspension down travel.
