Smart-Tech Overdrive Clutch Housing Kit

The Sonnax Smart-Tech Overdrive Clutch Housing Kit is engineered to enhance the performance and durability of Dodge 65RFE, 66RFE, and 68RFE transmissions. This advanced kit features a specially modified housing designed to hold a physically larger clutch pack, resulting in a significant 20% increase in clutch capacity. The enhancement extends to the materials used, with steels that are twice as thick and double-sided clutches, collectively boosting the overall steel mass by 28%. This increased capacity and mass are crucial for transmissions that experience higher torque loads or demanding operational conditions. By upgrading the overdrive clutch housing, this kit aims to improve the transmission's ability to handle power more effectively and reduce the likelihood of component failure under stress. The kit includes the necessary components to facilitate this upgrade, though it's important to note that some related service kits, like the 72960-11SVC, may have different screw counts and are not directly compatible with the bolt-on anchor plate found in the 72960-06K kit. Sonnax recommends using the updated 72960-12SVC in such cases. The 72960-06K superseded the discontinued 72960-16K, and has itself been superseded by the 72960-18K. While the 72960-18K offers improvements such as more screws for enhanced reliability, the core performance upgrades of the 72960-06K remain consistent in its successor.
