 Professional Products was founded in the late 1990s with a primary objective to provide quality high performance parts at better values than existed in the marketplace.  With the success of our first polished small block Chevy intake manifolds, we began expanding the range of products, always keeping in mind the end consumer’s need for good parts at a good value.


We are currently one of the industries’ largest suppliers of street and SFI-certified harmonic dampers, and also offer a full line of fuel system products.  Through our acquisition of Retrotek Speed, our areas of expertise have expanded into electronic fuel injection and ignition products.  We have worked to pioneer the self-contained EFI system with the Powerjection III.

Our core goal remains the same as when we started – provide good parts at a good price.
