SRP
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 lineup, including
Chevy, Ford, Chrysler, Honda
and more.
