Nitto RB *sine* drive crank collar (req'd for all sine drive pump applications)

Machined from high tensile 709 steel, the Sine Drive collar is exclusive to the Nitto range and can only be used in conjunction with the Nitto Sine Drive oil pump. Used in a multitude of high power street, drag strip, circuit and drift applications, this drive system is proven to work time and time again in the harshest of conditions. The Sine Drive collar uses the same M6 grub screws to lock the collar into place, with pilot holes machined into the collar as standard to guide your machinist to the optimal location for the grub screws. Each collar is hand checked and tested by a Nitto technician in order to maintain the ultimate quality control, ensuring that each and every collar meets our specifications.
