The 68RFE transmission, introduced in 2007 for Ram 2500 and 3500 pickups with the powerful 6.7L Cummins ISB Diesel engine, has become a staple in heavy-duty applications. While it shares design similarities with its 45RFE and 545RFE counterparts, the 68RFE features significant modifications to handle increased torque, including a larger bellhousing, revised gear ratios, and updated transmission controller programming. Despite these advancements, one common issue persists – overdrive clutch hub and shaft failure. Because OEM 68RFE Overdrive Hub is vulnerable to stress fractures at the two-piece adjoining weld and around the lubrication holes, leading to potential transmission failures. This problem affects both stock and high-performance applications, often starting with small cracks around the lubrication cross holes. These cracks can quickly spread, leading to catastrophic gear train failures that leave your vehicle sidelined.
TCS 68RFE Heavy-Duty, Performance Single-Piece Overdrive Clutch Hub and Shaft is CNC machined to eliminate these weak points, offering superior strength and durability. Designed to withstand the demands of both stock and high-performance applications, this upgraded hub ensures long-lasting, reliable performance for your transmission.
