This high performance billet supercharger shaft eliminates the weak design features of the OEM part. After analysing the OEM shaft R&D developed a new shaft design, superior in material strength and improved in every way.
It 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 pressed on gear shears off the end of the shaft. The one piece design will not allow the gear to slip under high boost loads like the pressed on OEM gear.
R&D have increased the inadequate 6mm thread diameter on the OEM shaft to utilise a larger well proven turbo spec, the new 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. The undercut or fracture point where the shaft meets the shoulder on the OEM design was also eliminated and replaced with a strong fillet radius and mating pressure plate. The new kit supplied pressure plate is designed to eliminate potential metal galling with higher boost.
The weight of this supercharger shaft has been decreased by 17%, eliminating the hex nut on the gear and pocketing the end of the shaft to significantly reduce reciprocating weight and adding to clutch performance.
Kit comes complete with new pressure plate washer, larger nut and installation instructions.
