USM was created by KLJ Corvettes for one reason in mind; to offer brand name parts at discount prices. KLJ Corvettes has been servicing the Maryland and DC areas for more than 20 years. We restore and repair C1-C6 Corvettes. And because of our many years in the performance field we have several suppliers 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.
