Performance Forged Pistons SRP pistons are specificly 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.
Professional Piston And Ring Kits Revolutionary piston kits combine lightweight, modern racing pistons and low friction metric ring sets with SRP quality and affordability. Profes- sional series kits include lightweight forged side relief (FSR) pistons with CNC-machined ring grooves and
skirts, dry filmed coated skirts, high quality, reduced length wrist pins with carbon steel wire locks, and JE
