2007.5-2024 Ram 2500 & 3500 6.7L Cummins RevMax Billet One-Piece Clutch Hub & Shaft Assembly Features:
68RFE 300M One Piece FORGED Billet Overdrive Clutch Hub and Shaft Assembly Patent No.: US D949,201 S
RevMax is proud to present the strongest and only true billet forged overdrive clutch hub for the 68RFE. This shaft fits ALL 68RFE’s both stock and aftermarket from 2008-2019! Unlike the competition who start with an OEM shaft, cryogenically treat, shot peen and tap it with a magic wand; RevMax's shaft is truly stronger. Not just in words but in real life physics and testing!
The stock hub and shaft is made of 4130 steel. RevMax's hot forged billet shaft is made of 4340M/300M steel. There is no comparison ins strength between the two metals. RevMax's base material is nearly 100% stronger than that of the OEM base shaft. No hocus pocus cryogenic heat treat and shot peening process will get you anywhere near what the material difference does.
RevMax doesn’t just use statistics to prove their products, they also use real world testing! RevMax sent the OEM hub, a competitor’s OEM cryo/shot peened hub and their own 300M forged hub to an independent third party government approved test facility. At the facility the parts were subjected to a torsional yield test that twists the shafts to their breaking point. The results prove just how much stronger our part is vs the OE and competition.
The benefits of the RevMax 300M Billet Overdrive Clutch Hub are far more than just material strength. Their shaft is a 1 piece design. The OE and competition shafts are two piece designs that require a friction weld to join the hub the and shaft. This weld is another fracture and failure point RevMax doesn’t have. Their shaft also allows the builder to build his OD clutch pack setup to his own specs and liking.
RevMax's shaft features the following benefits vs the competition and OEM stock shaft:
- Ability to run full thickness pressure plates while increasing clutch capacity by 28%
- Up to 50% more clutch capacity when using the industry standard .100” machined OD/Rev pressure plate.
- Longer clutch hub length allowing the installation of up to 20 single sided or 8 double sided frictions.
- One piece design that eliminates the weld from failing
- 4340M/300M billet hot forged material that is nearly 100% stronger than the OEM shaft
- Precision ground bushing surfaces
- Shot Peened lubrication holes to stop any stress cracks from forming
- Can be installed in a 100% OEM stock transmission without ANY modifications or into a transmission that incorporates any current aftermarket drum assembly.
