f These pinions are made from 303 stainless steel. Mod 1.5 for key way mounting onto 8mm shafts, perfect for Stooge open gear drive applications.
The keyed design saves your motor shafts from getting deformed by using set screw mounted pinions.
At 14mm thick, these pinions are nearly double the width of standard 8mm width RC car pinions. This extra width allows for the pinion to be flipped when one side is worn out to get another full cycle of use before your pinion needs to be replaced.
Sold as a single pinion in 4 sizes 15T, 16T, 17T, or 18T
