JE 279586R Piston Single SRP Pro 4032 (4.030 in. Bore, 1.110 in. CH, -5.00 CC) for CHEVROLET LS Gen III/IV Engine

Description JE 279586R Piston Single SRP Pro 4032 (4.030 in. Bore, 1.110 in. CH, -5.00 CC) for CHEVROLET LS Gen III/IV Engine

SRP Professional pistons combine forged piston durability with modern performance technology for a capable forged piston kit. Forged from 4032 aluminum, SRP Pro pistons experience minimal thermal expansion, making them suitable for reliable, high-performance engine builds from the track to the drag strip.

As with all JE Pistons products, SRP pistons are made 100% in the USA.

• 4032 forged aluminum provides tensile strength and minimal thermal expansion
• Proprietary Forged Side Relief forging design minimizes friction and power loss, reduces skirt width, and saves weight through a shorter Wrist Pin
• Low-friction skirt coating reduces wear and operating noise while optimizing performance
• Accumulator groove reduces combustion gas pressure, reducing Piston Ring flutter and improving ring seal for consistent power
