The STC8650 is a rear chassis crossmember assembly for the Defender 90, forming the structural closing section at the rear of the chassis rails and providing the mounting platform for the body tub, tow hitch, and related rear hardware. It includes the lateral extensions that tie into the chassis longitudinals, distributing load across the rear structure.
