Pistons was founded in 1997 by JE Pistons, the world's largest manufacturer of forged racing pistons. The idea was simple, to create a high quality forged piston at an affordable price. Every SRP forging was created with quality, performance and affordability in mind. By designing dedicated forgings, the pistons became both lighter and stronger while machining time and scrap aluminium were drastically reduced. These factors have reduced the price of SRP Pistons and contributed to their success. Today, over 400 different piston part numbers comprise the SRP product line-up, including Chevy, Ford, Chrysler, Honda
