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 72960-06K. 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.

  • Modified housing holds physically larger clutch pack for 20% more clutch capacity
  • 2X Thicker steels and double-sided clutches increase steel mass by 28% for unrivaled heat dissipation
  • Bolt-on anchor plate eliminates clutch pack flexing and distortion that contribute to heat build-up
