68RFE Heavy Duty Overdrive Clutch Hub & Shaft 2007-UP
Overdrive clutch hub and shaft failure is common in Chrysler 66RFE and 68RFE transmissions, in both completely stock units and heavy duty/performance applications. The failure always begins with small cracks at the lubrication cross holes that migrate through the rest of the shaft, eventually resulting in catastrophic gear train failure.
Sonnax heavy duty overdrive clutch hub and shaft 72570-01 is a critical upgrade to protect any vehicle at any power level. Sonnax cryogenically treats the OE hub and shaft to make the base steel more stable then shot-peens the lubrication cross holes to greatly reduce crack formation and increase load capacity. The result is a highly reliable hub and shaft assembly that’s an easy, direct replacement for all 66RFE and 68RFE units.
- Clutch hub and shaft is cryogenically treated
- Shot-peened lubrication cross holes
- Greater crack resistance than original hub and shaft
