RevMax just raised the bar again, meet the strongest and only true forged billet overdrive clutch hub for the 68RFE.
This one-piece, patent-pending design is crafted from 4340M/300M steel, blowing away the stock 4130 steel in both real-world abuse and lab-tested strength. We’re talking nearly double the tensile strength and over 110% more yield strength, no gimmicks, just hardcore materials and engineering. While some other shafts start with OEM parts and try to toughen them up with cryo treatments and shot peening, RevMax skips the shortcuts. This hub and shaft combo is hot forged as a single unit, no friction welds, no weak points. Just serious strength for serious builds. Better yet, it’s fully compatible with all 68RFEs, stock or built, and unlocks custom clutch stack configurations when paired with RevMax’s 9x or 12xR drums. Whether you're running single-sided or double-sided frictions, this setup is designed for max durability and flexibility under high power.
If you’re building your 68RFE to last, and to hold, this is the billet upgrade you’ve been waiting for.
