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 O.E. 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 takes the clearance out of spec and make overdrive clutch burnup inevitable.
Keep hard working 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 O.D. apply area by 16%. Plus, 2X thicker clutches increase clutch pack steel mass by 28% for unrivaled heat dissipation.
This ground breaking 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 distotion that contribute to heat build-up
16% more O.D. apply area for firmer, more controlled shifts
Combine with Sonnax line pressure booster kit RFE-RB1 for even higher levels of performance
This kit requires use of the input clutch retainer found in ’07-later units (O.E. part number 04799648AB) All 68RFE, 66RFE, 65RFE should have this retainer. For 45RFE and 545RFE ’99-’07 applications, the input clutch retainer must be replaced with ’07-later version.
