This Sherpa roof rack kit from Rugged Ridge includes the roof rack, crossbar adapters, and two 56.5-inch round crossbars. The Rugged Ridge Sherpa Roof Rack was designed to add valuable cargo space above the roofline of JK Wrangler. A true bolt-on installation, the Roof Rack requires no modification to the Jeep's body and features a unique tilt function for convenient access to your hard or soft top. With the Roof Rack system installed, hard top and freedom panels can be added or removed, and the soft top can be easily retracted or raised. Not compatible with Trektop NX Glide.
