About this kit
3.75-Inch Lift Kit with N3 Shocks, fitment-checked
Rough Country 646.20 is a 3.75-inch lift kit for the 1997–2006 Jeep Wrangler TJ 4WD SE, built as a combo of a 2.5-inch suspension lift and a 1.25-inch body lift with matched N3 shocks. It is a 4-cylinder application only, and it will not work on 2005-2006 models with the 6-speed manual transmission.
This 3.75-inch lift kit for the 1997–2006 Jeep Wrangler 4WD stacks a 2.5-inch suspension lift for the 4-cylinder TJ with a 1.25-inch body lift using fiberglass-reinforced nylon pucks, plus 2.5-inch N3 shocks valved for the application. Rough Country lists the install as bolt-on with no cutting or welding. Confirm your engine and transmission first: 6-cylinder Jeeps are excluded, as are 2005-2006 6-speed manual models. Running larger-than-stock tires on factory wheels can bring the tire into the lower control arm at full lock, so aftermarket wheels are recommended. A downloadable installation guide is available.
