Hurst Performance Inc. of Warminster Township, Pennsylvania, Pennsylvania, manufactured products for enhancing the performance of Muscle car. These included Manual transmission shifters and other automobile components. Hurst was also an Original Equipment Manufacturer (OEM) supplier for Automaker and provided services or components for numerous muscle car models by American Motors (AMC), Ford Motor Company, Chrysler, and General Motors. Their products were included in the AMC Machine, AMC AMX, Pontiac GTO, Ford Mustang Boss, Plymouth Barracuda, Plymouth Superbird, and Oldsmobile. Many renowned specialty models were produced in cooperation with the company and sported the Hurst brand as part of the official name. These included the AMC SC/Rambler, Jeep Jeepster, and various Oldsmobile Hurst/Olds models, based on the Oldsmobile Cutlass.
The original company was called Hurst-Campbell, which was co-founded by George Hurst in 1958 to make Hurst shifters and other aftermarket high-performance car parts. By the late 1960s, Hurst transmission shifters and other products became legendary in Auto racing, particularly in Drag racing and among Custom car makers. For example, many automobile enthusiasts replaced flimsy factory shifters with Hurst shifters to get better control of gear selection, particularly for competitive driving. The Hurst units were so good that U.S. automakers were forced to offer it, although they preferred making their own parts. 
The company was bought out by Sunbeam Products in the early 1970s and later became part of the Mr. Gasket Company.
Hurst is now part of B&M Automotive Products .
