In fact, Steve’s entire professional career has been devoted to the Differential Industry. In those years, Steve has not only gained vast experience and knowledge of the Automotive, Light Truck, Heavy Duty Truck, and Service Industry differentials; he has established himself, and A1 Differential as an innovator in the Off Road and Racing circles! So, if you are looking for a company and someone who has depth of knowledge, years of hands on experience, someone who has devoted himself to specializing in one industry, someone that wakes up in the morning and goes to sleep at night thinking about Rear Ends, then Steve and A1 Differential would like to be your Rear End Specialists.

It should go without saying that a Quality job requires, not only Quality work, it requires Quality parts. With over 20 years of experience Steve has extensive knowledge of the parts available in the Differential industry. It might be tempting to save a few buck$ on cheep Off Shore parts, but not at A1 Differentials. Steve and A1 were Born in the USA and so are the parts used at A1 Differential. For Steve and A1 “Made in the USA”, and the Quality that comes with it, is not an option, it is a requirement.
At A1 Differential it really is pretty simple, Use the Right Stuff, Put it in Right, and Charge a Fair Price!

That concept has made America Great and it is one that A1 Differential lives by.
