SRPPistons was founded in 1997by JE Pistons, the world'slargest manufacturer offorged racing pistons. Theidea was simple, to create ahigh quality forged piston atan affordable price. EverySRP forging was created withquality, performance andaffordability in mind. Bydesigning dedicated forgings,the pistons became bothlighter and stronger whilemachining time and scrapaluminium were drasticallyreduced. These factors havereduced the price of SRPPistons and contributed totheir success. Today, over400 different piston partnumbers comprise the SRPproduct line-up, includingChevy, Ford, Chrysler, Hondaand more.
