World Class Design and
Quality Transmission Gears

There is a lot more to designing and manufacturing gears for automotive performance racing applications than applying standard text-book tooth design formulas and then using traditional off the shelf gear generating tools. There must be real understanding and strong committments in many areas.  The four people most involved with gear design and manufacture at Andrews Products have over 80 years of cumulative experience.   Gear manufacturing also includes investments in in-house gear design programs, state of the art CNC gear cutting machine and CNC inspection equipment.  All Andrews Products gears are approximately 15% less weight than other  top loader gears. The end result is the strongest, most reliable gears possible.  All of these factors helps to put Andrews Products' customers one step closer to the winners circle.

Either of these two CNC gear machines can be programmed to produce tooth modifications which make it possible to design and manufacture the highest quality tooth designs and the strongest, most reliable finished gear teeth.
