Sonnax Chrysler RFE Heavy Duty Inner Retainer Housing Kits

Sonnax Chrysler RFE Heavy Duty Inner Retainer Housing Kits

Dodge trucks are at high risk for Overdrive failure from clutch wear on the inner retainer housing. To stop wear forever without excess weight, Sonnax heavy duty inner retainer housing kits combine patented steel inserts with a modified OE aluminum housing. It’s an ideal durability upgrade for stock or modified vehicles with 45/545RFE (’07-later), 65/66/68RFE transmissions.

Sonnax offers two kits at two different price points to deliver the same, great durability:

  • #72554-11K remanufactured version featuring a used OE retainer
  • #72554-01K all-new kit
