The part of the involute 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.

Genuine HT spare/option part. Nitrited steel spur gear, profile regraded, for combination with the stock 43T spur gear which goes on the clutch bell. This gives a numerically lower drive ratio and makes it possible to use standard diameter buggy tires on this car!Attention: The speedgear has the same diameter as the stock 37T gear and is therefore not compatible with the other 37T/40T HT tuning gears!Speedgear 34T: I=7,74Module: m=1,5Profile regraded, this means that the number of teeth is changed while the diameter remained constant.
