Proform Innovation

PROFORM owns the trademarks for dozens of components and product designs and is constantly developing new products as well as expanding and improving their existing product offerings. They were the first to make affordable, non-remanufactured car parts and accessories widely available and were the first to offer the two-piece timing chain cover, the two-stage in-line fuel filter, HEI distributor tune-up kits, and direct-replacement carburetor main bodies. Furthermore, they were the first to popularize GM Officially Licensed parts with the popular Chevrolet, Bow Tie, and other divisional trademarks, as well as Ford Performance Licensed products with the Ford (sold under the PROFORM Factory Performance Parts designation).

Proform Quality

Proform offers unique tools, alternators, stock harmonic balancers, and distributors; a line of roller-tipped rocker arms with the widest selection of manufacturing processes (stamped steel, cast chrome moly, and machined extruded aluminum); and a complete line of popular and easy-to-use engine builders' tools made to intricate specifications.

PROFORM PRICING

Proform Parts are engineered to deliver the optimal balance of high quality and economic price value. These prices are the consequence of a skilled and efficient global manufacturing process, not of cost cutting.

Proform is the factory source for Licensed Chevrolet Performance Engine Dress Parts, Licensed Ford Performance Products, carburetors, HEI distributors, electric water pumps, electric fans, engine components, and street performance equipment.
