Your 9" gear set combo was so impressive after the first lap, that I thought people were behind me bumping to get by. While in fact, it was pure traction that was never felt before. A few adjustments and it was game on! Thank you so much for the support, I just can't express enough the difference your product made on the truck's performance.
I would like to thank all of the people from US Gear for manufacturing the highest quality ring and pinions on the market, which are all made in the USA. Not only did we run our fastest ET, but we were able to put 35 runs on it which is ten more passes that we have ever gotten out of other company gears. Thanks again for a great product!
