Over sixty years of gear manufacturing "know how" was designed into our Pro Gears. We start by using the highest quality 8620 steel. The we precision hob them to AGMA Class 8 tolerances to produce true involute tooth form for a high contact ratio. We finish them with a proprietary heat treat process then hand roll test and inspect each and every gear set giving you results on the track that can't be beat! These quick change gears are specifically designed to run smoother and last longer than anyone else's and are the finest quick change gears available in the marketplace today!
