68RFE 300M One Piece FORGED Billet Overdrive Clutch Hub and Shaft Assembly *Patent Pending*
We are proud to present the strongest and only true billet forged overdrive clutch hub for the 68RFE. Our 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; our 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. Our hot forged billet shaft is made of 4340M/300M steel. There is no comparison ins strength between the two metals. Please read the chart below to see for yourself. Our 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 our material difference does.
