Fabricated by highly trained and experienced welders using precision tooling. All joints are MIG welded while all brackets are installed using precision TIG welding. Today’s High Performance engines require the strength and reliability these round back housings provide.

TCI Engineering fabricates all of its 1970-1981 Pontiac Firebird Currie 9″ Ford Rearend housings in-house using only high quality 100% Curries 9-Plus rear end components. Modeled after the popular factory 9” Ford stock housing which is now nearly extinct, the 9-Plus Hot Rod housing is similar to the early style . The 9-Plus model is made of U.S. supplied premium grade formed steel. Strength and rigidity is increased by using thicker gauge steel. The housing comes with American Made 3” O.D. x .188” wall 1026 D.O.M. steel tubing. 100% new Billet steel 9-Plus late model large bearing (Torino style) housing ends. Exhaust routing is made easier and bracket clearance is increased due to the shape of the housing.
