SRP Pistons wasfounded in 1997 by JEPistons, the world's largestmanufacturer of forged racingpistons. The idea was simple,to create a high qualityforged piston at anaffordable price. Every SRPforging 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.
