MSR Racing produces fully built Ford 6R80 transmissions and billet parts. The MSR billet 6R80 parts are the next step in making your 6r80 able to support over 1000whp! They are a direct replacement of the weak stock parts and will not change any function of the trans or require any additional tuning. MSR Racing also builds complete 6R80 performance transmissions proven for heavy street or strip use. Team Beefcake Racing is an Authorized Dealer.
