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. Fitment on this page is based on the manufacturer’s application data.
About this kit
4-Inch Lift Kit with M1 Shocks, fitment-checked
Rough Country 68140 lifts the 2007-2017 Jeep Wrangler Unlimited 4 inches using the 681 kit box and two M1 Monotube shock pairs. It is a 4-door-only application — 2-door Wranglers are not covered. Keeping factory wheels means adding 1.5in wheel spacers, and 2012-2018 Jeeps need exhaust modification for front driveshaft clearance.
Four-door owners are the audience for this 4-inch lift kit for the 2007-2017 Jeep Wrangler Unlimited, listed for Sport, Sport S, X, Sahara, Rubicon, and the 70th and 75th Anniversary submodels; 2-door bodies are excluded. Contents are the 681 kit box plus two M1 Monotube shock pairs, with rear coil correction plates that shift the coil spring angle by 10 degrees. Assembly bolts on with no cutting, and clearance allows tires up to 35 inches. Automatic-equipped Jeeps flexed hard with the sway bar links disconnected can see front driveshaft-to-transmission-pan contact; a smaller-diameter aftermarket shaft corrects it. A downloadable installation guide is available.
