This billet aluminum transmission crossmember provides unique styling with the strength of billet. Designed as a direct replacement for 1979-1993 fox bodies, it also provides clearance for dual exhaust systems. There is no welding with the Southside Machine design, and transmission locations are secured by self-locking stainless steel sets. The billet aluminum construction eliminates EM 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.)
