USM was created by KLJ Corvettes for one reason in mind; to offer name brand parts at discount prices. KLJ Corvettes has been in business for 15 years and because of our many years in the performance field we have picked up several vendors along the way. Now, with Ultimate Street Machines, we can pass on the discounts not to just local customers, but to every customer. We also have an extensive listing of OEM & restoration parts. Again, our service & parts sales experience has help us selectively compose a catalog of commonly needed parts as well as the hard to find parts that are often overlooked when planning & project. We hope you enjoy shopping at our website and continue to do so as your need for horse power grows.
