High Performance Automatic Transmission Accumulator Piston Kit (44894-01MK) by Sonnax®. Includes: Pistons (5), Guide Seals (10) PTFE, Solid, Seals (5) PTFE, Scarf Cut. Quantity: 5 Pcs. Accumulator piston scuffing and bore wear are common issues in valve bodies, especially when running increased pressures. The OE accumulator pistons have two seal rings. The seal groove at the open end of the piston is a larger diameter, with the seal ring acting as a guide to prevent piston-to-bore contact. The seal groove at the closed end of the piston is a smaller diameter and the seal ring acts as a conventional seal. However, due to the smaller seal groove diameter, the piston will contact the bore when side-loaded resulting in scuffing, wear and leakage of clutch apply pressure.
