JE Pistons / SRP · 377889

Description

Features & benefits

• Forged in the USA using 2618 aluminum, yielding high tensile strength needed for high-demand performance applications
• Pin Fit: The pin bore is precision honed to attain an exact pin clearance. Clearances typically range from .0003 to .0010 between the wrist pin and pin bore.
• Econo Undercrown Milling: Creates a lighter, more durable piston with uniform deck thickness in critical areas, offering excellent value through efficient machining.
• Vertical Gas Ports: Machined gas ports channel combustion pressure behind the top ring for improved cylinder sealing and reduced blow-by under high load. Common in drag racing applications where maximum ring seal is critical.
• Ultra Groove: Specialty ring groove machining process that provides near perfect groove flatness and surface finish. Tolerances are held to the millionths of an inch.
• Designed specifically for Chevrolet Big Block SR20 Headed Engines. To provide optimized performance durability
• 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
• Includes high-quality wrist pins, and locks
• Made 100% in the USA
• Smooth Crown Finish: Deburs all areas around the valve pocket and dome area, to reduces stress risers and prevent hot spots.
• Contact Reduction: Reduce the amount of contact area against the cylinder wall when the piston "Rocks over". Contact reduction also serves to disrupt the flame travel into the crevice area causing a reduction in detonation.
