Dodge trucks pulling heavy loads or boosted to 400–600HP are at high risk for overdrive burnup due to the stock transmission’s insufficient clutch capacity and fragile OE clutches.

Even small amounts of heat and extra torque will push the thin (.034"), single-sided clutches over the edge, distorting the clutch pack. The fact is, any distortion of the clutch pack takes the clearance out of spec and makes overdrive clutch burnup inevitable.

Keep hardworking trucks on the road with the Sonnax Smart-Tech® overdrive clutch housing kit 72960-16K. The unique billet aluminum housing holds a physically taller clutch pack and increases OD apply area by 16%. Plus, 2X thicker clutches increase clutch pack steel mass by 28% for unrivaled heat dissipation.

This groundbreaking new kit is the only top-of-the-line upgrade that eliminates clutch problems without relying on valve body/pump modifications or adding the expense of extra components.

  • Custom housing holds physically larger clutch pack for 20% more clutch capacity
  • 16% More OD apply area for firmer, more controlled shifts
  • 2X Thicker steels and double-sided clutches increase steel mass by 28% for maximum heat dissipation
  • Custom BorgWarner clutches for maximum capacity with state-of-the-art squawk resistance.
  • Bolt-on anchor plate eliminates clutch pack flexing and distortion that contribute to heat build-up
  • Combine with Sonnax line pressure booster kit RFE-LB1 for even higher levels of performance
Note:
This kit replaces the original Sonnax Smart-Tech overdrive clutch housing kit 72960-06K. The new and improved kit features clutches optimized for capacity and squawk resistance plus longer, flange-head plate screws for extra secure fit and optimal clamping force.

OE Part No. 52119776AA

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
