1979-1993 Ford Mustang Billet Aluminum Crossmember


Model: RCMFB


This billet aluminum transmission crossmember provides unique G Force styling with the strength of billet. Designed as a direct replacement for 1979-1993 fox bodies, it provides clearance for dual exhaust systems. There is no welding with the G Force design.  Transmission locations are secured by self-locking stainless steel sets. The billet aluminum construction eliminates the OEM style spongy” rubber inserts, and bolts in solid for a chassis stiffening assembly. This crossmember provides a level of function that is equal to it’s great looks and styling.

(direct bolt-in for vehicles built since 1982 with a 4-1/2″ dimension between the crossmember mounting brackets. Earlier vehicles with the 2-3/4″ dimension are accommodated by relocating the brackets.)
