Product Description
The factory 68RFE overdrive clutch hub and shaft assembly is a known weak point in high-torque Cummins applications. The REVMAX 68RFE-502 replaces the factory two-piece design with a one-piece forged 300M billet hub and shaft assembly, dramatically increasing strength and eliminating a common failure point in performance and heavy towing builds.
Machined from forged 300M alloy steel, this assembly is engineered for extreme torsional strength and durability in high-horsepower, tuned, and towing-focused 6.7L Cummins trucks.
Why Upgrade to the 68RFE-502:
- One-piece design eliminates factory two-piece separation issues
- Forged 300M alloy steel construction for superior strength
- Ideal for tuned, deleted, heavy tow, and performance applications
- Precision-machined for direct-fit installation in 68RFE transmissions
Fitment:
- 2007.5–2018 Dodge Ram 2500 / 3500
- 6.7L Cummins Diesel
- 68RFE Automatic Transmission

FAQ
Why does the factory 68RFE hub and shaft fail?The OE two-piece design can separate or twist under increased torque loads. A one-piece forged 300M unit eliminates that structural weakness.
Is this required for tuned or deleted trucks?
While not mandatory for stock trucks, it is highly recommended for tuned, heavy towing, or higher horsepower applications to prevent costly transmission failure.
Will this fit all 68RFE transmissions?
This assembly is designed for 2007.5–2018 Ram trucks equipped with the 68RFE behind the 6.7L Cummins. Always verify transmission model before ordering.
Is professional installation recommended?
Yes. Installation requires transmission disassembly. Professional installation or experienced builder-level expertise is strongly recommended.
Does this carry a Prop 65 warning?
Yes, this product is commonly listed with a California Prop 65 warning. See the specification table above for details.
