Fitment and installation notes

Does NOT fit 2-door models. 2012-2018 models require exhaust modifications to clear the front driveshaft SKU: 1030 . If using stock wheels 1.5in wheel spacers are required. On Automatic equipped vehicles; due to use of an oversize driveshaft from the factory and inadequate factory clearance it may be possible for the front driveshaft to come in contact with the automatic transmission pan tearing the factory boot and rubbing on the shaft. Generally this occurs during heavy articulation when front sway bar links are disconnected and longer shocks are installed. If this is found to occur, the proper procedure would be to replace the oversize factory shaft with an aftermarket smaller diameter shaft to increase clearance between the transmission and front driveshaft. Rough Country does offer this driveshaft if needed.

Vehicle fitment
