We designed this crossmember for the Jeep LJ's to provide axle and upper link clearance for maximum up travel. When the rear axle is stretched back on the LJ's the factory crossmember limits up travel. Laser cut, formed and welded from 3/16" steel plate. The original crossmember gets cut out and our new heavy duty one welded back in it's place or 1" higher to eliminate the need for a 1" body lift spacer. Designed to fit with Genright stretch fuel tanks.
