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!
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.
It’s been my philosophy to get the best parts money could buy. US Gear builds the best product out there.
We love the high quality ring & pinions. Quiet gears = happy customers!
Here at Moser, we understand that gear sets require a level of attention that borders on art as much as science...a knack for knowing how, why, and when to apply a skill set. It is with confidence that we recommend US Gear, as they have long been a timely supplier of the highest quality and have dependable delivery times.
It was unanimous to work with US Gear. We use the 10” Pro Lightning Series set up and it’s just been absolutely phenomenal. We have had zero failures through all of the conditions that we’re racing in Ultra4.
