Many OE supports in Chrysler 46RH/RE, 47RH/RE and 48RE units do not seal well against the case, leading to reduced lube flow to the gear train and consumption of pump volume. Sonnax oversized piston retainer kit 22754N-02K salvages damaged Reverse drums and maximizes gear train durability by preventing the loss of lube oil between support and case.

  • Oversized diameter is ideal for damaged drums; installation requires turning the I.D. of the drum using a lathe
  • Unique design features two sets of I.D. and O.D. grooves repositioned at key load areas improve oil delivery
  • O-Ring improves case seal and prevents loss of lube oil
  • High-quality aluminum alloy resists gauling for better wear resistance
  • Kit includes two optional plugs for use in RE unit
