We don't just use statistics to prove our products we also use real world testing! We sent the OEM hub, a competitor's OEM cryo/shot peened hub and our 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. Please see the data below:</ptable id="tablepress-3" class="tablepress tablepress-id-3"> ShaftTorque Before BreakingStrength increase vs OEMOEM Competitor's OEM cryogenically treated and shot peened Revmax 300M Forged The benefits of the RevMax 300M Billet Overdrive Clutch Hub are far more than just material strength. Our 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 we don't have. Our shaft also allows the builder to build his OD clutch pack setup to his own specs and liking. When using our shaft along with our RevMax 9x or RevMax 12xR drum assembly with billet forged pressure plates, you now have multiple options for clutch stackup. Using our drum, pressure plates and billet OD hub, these are just a few of the options you now have:</ptable id="tablepress-4" class="tablepress tablepress-id-4"> Friction SetupOD/Reverse Pressure Plate% Increase over OEM clutch surface area16 Single SidedFull Thickness, .365" Thick28.5%18 Single Sided.265" thick machined pressure plate40%20 Single Sided.265" thick machined pressure plate50%6 Double Sided w 5 .067" SteelsFull Thickness, .365" Thick0%7 Double Sided w 6 .067" Steels.265" thick machined pressure plate28.5%8 Double Sided w 7 .067" Steels.180" thick machined pressure plate40% Our 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.
