SonnaxPiston and Sleeve Kit

The 1-2 accumulator bore on Ford AX4S, AXOD and AXODE channel castings can become scored which creates loss of clutch pressure or cross-leaks. The continuous oscillation of the piston within the bore causes excess wear. In addition, a broken accumulator spring can get caught between the piston and the bore causing a deep groove in the casting wall. You can resolve these problems by installing Sonnax 1-2 accumulator bore sleeve kit S86927K. Kits contain an aluminum sleeve and new steel accumulator piston with a Viton® O-ring; Piston is compatible with all OE springs and OE piston pins; Length of piston-to-pin contact area has been increased to reduce piston cocking and increase sealing surface area; Drop-in Zip Valve™ parts install quickly and easily
