Performance Carb

APS Racing USA got its start in the early 90s fabricating top quality sheet metal and billet aluminum valve covers. Our highly sought after custom valve covers have been featured in several magazines including Super Chevy, Custom Fabrications, Rod & Custom & Chevy High Performance We expanded the business to include fabricating custom plenums, intakes, transmission and oil pans. All of our custom products are made from the best quality USA aluminum available. Due to the fact that custom work is very time consuming and the current state of the economy, we were forced to downsize. In our attempt to simplify things we currently only offer our most popular custom valve covers. If you’re racer or street enthusiasts and are looking for the best aluminum products on the market you have come to the right place. Keep in mind that our custom valve covers are made to order and require additional time to manufacture. We understand that not everyone has the budget to purchase or requires such a quality product. So we also offer other valve covers not manufactured by APS Racing USA. See our eBay store where we are now introducing other quality automotive aftermarket/racing products at a competitive price

We will be adding extra features over the next few months, so come back regularly.
