Description
SRP Professional pistons combine forged piston durability with modern performance technology for an extremely capable forged piston kit that doesn’t break the bank. Forged from 4032 aluminum, SPR Pro pistons experience minimal thermal expansion, making them perfect for a high-performance, reliable engine build from the track to the drag strip. All SRP Pro pistons include premium ring sets, wrist pins and locks. As with all JE Pistons products, SRP pistons are made 100% in the USA.
- Forged in the USA using 4032 aluminum, yielding tensile strength and minimal thermal expansion
- Proprietary Forged Side Relief (FSR) forging design minimizes friction and power loss with reduced skirt width and saves additional weight with a shorter wrist pin
- Low-friction skirt coating reduces wear and reduces operating noise while optimizing performance
- Includes high-quality wrist pins, locks, and JE Pro Seal premium piston rings
- Accumulator groove helps reduce pressure from combustion gases, reducing ring fluttering and improving ring seal for consistent power
- Made 100% in the USA

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 line-up, including Chevy, Ford, Chrysler, Honda and more.
