By using aluminum screws,  we are eliminating magnetic drag and interference that is caused by normal magnetic metals. These will help unleash each motors true potential. The end result is an increase in RPM on the dyno (under load) and improved efficiency.  Also saves a little weight too. These are for a racer wanting the best possible edge. These fit all R1 Wurks V21 motors.

You get:
3 Aluminum Stator Screws
3 Aluminum Timing Ring Screws

Easy to install.
