About this kit
4-Inch Lift Kit with N3 Shocks, fitment-checked
Rough Country 90730 is a 4-inch lift kit for 2003–2006 Jeep Wrangler TJ 4WD models, shipping as a coil box paired with a 4in N3 kit box. Automatic-transmission Wranglers may need a SYE and CV driveshaft to settle driveline vibration, and adjustable lower control arms (SKU 1190) may be needed alongside them.
This 4-inch lift kit for the 2003–2006 Jeep Wrangler TJ 4WD covers SE, Sport, X, Sahara, Rubicon, Unlimited, Unlimited Rubicon, and 65th Anniversary Edition applications listed in the fitment section. It bolts on without cutting or welding, and the two-box kit pairs the TJ coil box with the 4in N3 kit box, so N3 shocks, coil springs at factory-matched rates, control arms with rubber bushings, and a tubular transfer case drop are all part of the package. Plan for the automatic-transmission driveline caveat before ordering, then work from the downloadable Rough Country installation guide.
