Overdrive Clutch Housing Drum Assembly

Dodge trucks pulling heavy loads or boosted to 500–600HP 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. Any distortion of the clutch pack takes the clearance out of spec and makes overdrive clutch burnup inevitable. The unique billet aluminum housing increases OD apply area by 16% and holds a physically taller clutch pack.

• Modified housing holds physically taller clutch pack for 20% more clutch capacity
• 16% More OD apply area for firmer, more controlled shifts
• 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
