48 Pitch Pinion Gears

HPI 48 pitch pinion gears are made from high-strength steel and have all unnecessary material removed for a lower rotating weight. All off-road racers should use these gears, and some modified Touring Car racers use these for racing because of the extra toughness of 48 pitch pinion and spur gears! Each gear is stamped with its size for easy identification.
