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. 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 increases OD apply area by 16% and holds a physically taller clutch pack. The 2X thicker steels increase clutch pack steel mass by 28% for maximum heat dissipation. The double sided BorgWarner clutch frictions are optimized for the 68RFE OD application and custom-made for the Sonnax kit. This guarantees an unrivaled combination of squawk resistance and maximum clutch capacity for any truck.

这种突破性套件是唯一的唯一升级，可消除离合器问题而不依赖阀体/泵修改或增加额外组件的费用。
