Since its introduction in 1969 with the 428 SCJ, the R-code servo has remained the trick piece for C-6 builders needing additional band apply force. Ford last offered an OEM replacement in 1992. Sonnax is reintroducing this servo kit with our unique "no-leak" servo pin. This pin uses two O-rings to eliminate back pressure and leakage due to worn case bores. The kit includes: piston and pin, cover, gasket, high temperature O-rings, and (3) selective return springs.
