Professional Manufacturing Quality: Richmond Gear ring and pinion sets are manufactured using computer-controlled processes from the foundry through precision gear cutting to heat treatment. Each gear is cut to 1/1000th of an inch precision, ensuring optimal tooth contact, reduced noise and vibration, and maximum durability. The result of decades of racing development and state-of-the-art manufacturing methods, Richmond gears consistently deliver some of the strongest performance available.
