The GPM 16T steel pinion is profile regraded. This allows for a change in gearing by a pinion swap alone. The pinion has the same dimensions as the HPI 17T stock pinion.Module: m=1,5Profile regraded means that the number of teeth is changed while the diameter remained constant. The part of the involutes? curve that defines the tooth profile is changed. Positively regraded (lower number of teeth) pinions are stronger and run smoother, the reduced strength of negatively regraded pinions doesn?t really matter.
