Performance Forged Pistons
SRP pistons are specially designed forgings that eliminate several phases of the manufacturing process, saving time and cutting costs
with high-volume production. Most pistons are made of 4032 high-silicon aluminum, a material that withstands the tight clearances in
street/strip engines. All pistons are machined to accept 1/16" top, 1/16" second, and 3/16" oil rings. Sold in sets of eight, with wrist
pins and double Spiro Locks.
