JE 329447 Piston Kit SRP Pro 4032 (4.135 in. Bore, 1.125 in. CH, 4.00 CC) for CHEVROLET Small Block Engine

Description JE 329447 Piston Kit SRP Pro 4032 (4.135 in. Bore, 1.125 in. CH, 4.00 CC) for CHEVROLET Small Block 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
