About Professional Products
Professional Products has been a fixture in the aftermarket engine performance world for decades, tracing its roots all the way back to 1972 when its founders entered the racing industry as part of Brock Racing Enterprises. What began as a passion for motorsport quickly evolved into a full-scale manufacturing and distribution operation, as many of those same racing-derived components found their way into American muscle cars on the street. Over the years, the brand has remained committed to delivering high-quality performance parts that offer real value to the enthusiast — not just race teams with unlimited budgets.
Headquartered in Hawthorne, California, Professional Products has grown its catalog steadily by following the needs of builders and tuners. Engine harmonic balancers have long been the brand's flagship product line, offered in a wide range of configurations — from restoration-correct dampers to SFI-rated race units — covering popular platforms like Small Block Chevy, Big Block Chevy, Small Block Ford, and Chrysler engines. These dampers are engineered to protect the crankshaft from the destructive torsional vibrations that build up under hard use, making them a critical investment for any serious engine build.
Alongside its damper lineup, Professional Products has built a strong reputation for engine intake manifolds and performance intake manifolds that span a broad RPM range and fit both carbureted and fuel-injected applications. Their Crosswind, Typhoon, and Cyclone series manifolds cover platforms from classic small block Fords to modern LS engines, and are available in polished, satin, and matte black finishes to suit any build aesthetic. The brand even earned recognition at the SEMA show with a Best Engineered New Product award, a testament to their continued focus on innovation.
Rounding out the crankshaft-related product family, Professional Products also manufactures precision engine crankshaft pulley spacers and engine crankshaft spacer rings — small but vital components that ensure proper belt alignment and damper positioning on custom builds and engine swaps. These accessories are a natural complement to the brand's damper lineup and reflect the company's approach of offering everything a builder needs to complete the front of an engine correctly.
Whether you're restoring a vintage V8, building a dedicated track car, or upgrading an LS swap, Professional Products offers a focused, well-engineered catalog that has earned the trust of enthusiasts and professional engine builders alike.
