904, 727 Rear Servo Piston Pin/ Plug

A727, A904 Reverse Servo Piston Plug Kit

Part No. 22912-01K

There are two styles of the OE Reverse servo piston plug in Chrysler RWD units:

• The extended tip version for the 47RH/RE (A618) and 48RE
• The flat tip version for the 40RH, 42RH/RE, 44RE (A500), 46RH/RE (A518), 36RH, 37RH (A727) and 30RH (A904).

Both versions of these OE aluminum plugs are subject to wear, galling and breaking at the spring seat area due to high stresses in Reverse. Sonnax steel reverse servo piston plug kit 22912-01K won't break or wear like the OE plug and can be configured to work in both styles of RWD units.

• Hardened steel for more than twice the strength of OE plugs
• Exclusive, leak-free design uses O-ring between plug and piston
• Universal replacement for both extended and flat-tip plug styles
