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!

Whether you're running a stock flattie and rearend or hopped-up overhead and quick change, you need to run a good gear lube. Remember that your rearend was designed fifty plus years ago and needs all the help it can get.
The biggest improvement you can give it is a lubricant that will allow the gears to survive the highway speeds that cars see today. L.E. gear oil is what we use in our 350 mph streamliner, that uses a V-8 quick change, without failure. The "red stuff" provides superior lubrication for long gear life. You can't win if you don't finish. We suggest 90 weight for the street and 140 weight for extreme uses.
