A431 Transmission 
There is more to the design and manufacture of transmissions and gears for automotive racing than applying standard text book tooth formulas and using off the shelf gear generating tooling.
True understanding and strong commitments are required in many areas. The four people involved with gear design and manufacture at Andrews Products have more than 90 years of cumulative experience.
Gear manufacturing also includes investments in gear tooth design software, state of the art CNC gear machines and CNC inspection equipment.
Andrews Products transmission gears for racing are approximately 15% lighter than gears made by competitors. The end result means the best, most reliable gearing available. All of these factors place Andrews customers one step closer to the winners circle.
Our CNC gear machines are programmed to produce the highest quality gears and the strongest, most reliable finished gear teeth possible.
