RTS Transmission Extension Tail Housing, Upgraded For Ford C4/C5/C9/C10

The C4 has been a popular choice for performance applications, including drag racing, due to its light and relatively simple design and the availability of aftermarket parts and upgrades. 

RTS is proud to announce, we have made a ALL new extension housing with notable improvements where the original Ford unit was lacking. This new extenion housing is perfectly suitable as a stock oem replacement for a tired old original unit that might be cracked or warped etc, but also a pefect pairing to the ALL RTS C4 case that is currently under devlopment.

  • Low pressure casting compared to factory version which is die cast
  • Cast from high quality A356-T6 heat treated aluminium
  • Increased thickness near rear seal flange which was prone to housings cracking 
  • Increased bolt flange thickness to eliminate warping
  • Increased gasket sealing surface area which will match RTS case improvements when released
  • 1/8 Npt tapped breather hole, made ready to attach remote breather or catch can
  • Rear bush and seal installed for your convenience and ready to use
