- Dodge trucks with Chrysler RFE transmissions are at high risk for overdrive failure due to clutch wear on the inner retainer housing. Damage builds up over time, causing the clutches to drag, affecting apply and release. To eliminate all risk of wear, Sonnax heavy duty inner retainer housing kit 72554-01K features a specially modified OE retainer and hardened steel inserts to upgrade durability of '07-later 45RFE and 545RFE, plus all 65RFE, 66RFE and 68RFE units.
The Sonnax retainer is an ideal upgrade for improving transmission durability in any stock or modified vehicle. All OE cast aluminum retainer and aftermarket billet aluminum retainers, even those that are hardcoat anodized, will inevitably wear. Steel retainers are not an ideal option — due to their excessive weight, they overstress support bushings throughout the transmission.
- Tough steel inserts prevent wear in OD clutch area of new aluminum retainer
- Replaces stock retainer in OE overdrive housings and Sonnax Smart-Tech® overdrive clutch housing kits
- Compatible with single- and double-sided clutches
- Two kits available at two price points to deliver the same, great durability: this all-new kit and a remanufactured version 72554-11K featuring a used OE retainer
