Bore wear and accumulator piston scuffing are frequent problems with Chrysler valve bodies, particularly when operating at higher pressures. Two seal rings are present on the OEM accumulator pistons. The piston’s open end has a seal groove with a larger diameter, and the seal ring serves as a guide to keep the piston from making contact with the bore. The piston’s closed end has a seal groove with a smaller diameter that serves as a traditional seal. The piston will, however, come into contact with the bore when side-loaded, causing scuffing, wear, and clutch apply pressure leakage because the seal groove’s diameter is smaller.
Three guide seal rings are included in this set; one at each end of the piston – and one in the middle, to prevent piston-to-bore scuffing under side loading. These pistons are made from 6061 billet aluminum, will replace the plastic ones in late-model applications and prevent transmission failure from piston breakage.
