4.185 in. Bore – 1.165 CD – (-5.00 cc) – 8 Cyl. Piston Kit
These pistons utilize our dedicated Forged Side Relief (FSR) forging that was specifically designed to increase strength.

• 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
• Accumulator groove (depending on application) helps reduce pressure from combustion gases, reducing ring fluttering and improving ring seal for consistent power
• Skirt coating (depending on application) reduces friction and wear on piston skirts and cylinder walls while simultaneously reducing operating noise
• Forged in the USA using 2618 aluminum, yielding high tensile strength needed for high-demand performance applications
• Designed specifically for each engine and use application to provide optimized performance durability
• Made 100% in the USA

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.
