    R&D billet supercharger shaft available for pre order

    These will begin shipping at the end of the month.

    Please pre order here

    R&D's new High Performance Billet Supercharger Shaft eliminates the weak design features of the OEM and aftermarket HKS supercharger shaft. After analyzing the OEM HKS shaft design and sorting through the various failures we had with it while testing our popular Monster S/C Wheels, we developed a superior shaft design.
    The new R&D shaft is not a copy of the fragile HKS design. Rather, it is a completely new design, superior in material strength and improved in every way.

    The new R&D Shaft is precision cnc machined, heat treated, and precision ground from billet steel alloy. Featuring a uni-structure design that incorporates the shaft and gear as one billet piece, much like a transmission shaft. This eliminates the fracture point on the OEM design where the gear shears off the end of the shaft. The billet design will not allow the gear to slip under high boost loads like the pressed on OEM gear.

    Next we increased the inadequate 6mm thread diameter on the OEM shaft to utilize a well proven “Turbo spec” LARGER 5/16-24 left handed thread that will not break under extreme conditions. The larger thread diameter will also allow wheel torque specs to be increased safely.

    Lastly, we reduced the weight of the R&D Supercharger shaft by eliminating the hex nut on rear the gear and lightened the end of the shaft/gear inside diameter to significantly reduce reciprocating weight. We all know what that will do to add to clutch performance. Used by Chris MacClugage to win the 09’ APBA Pro Open Runabout National Championship. Kit comes complete with larger nut and installation instructions. All in all, the new R&D High Performance Billet Racing Shaft is not just a replacement shaft, but a solution to end all supercharger shaft problems.

    Proudly Made in the USA!

    Available for pre order now, shipping 9/30/09
