Description

It features a flat top crown with 4 valve reliefs and an offset pin configuration with a press pin type. The piston has a bore diameter of 4 inches and a compression height of 1.719 inches, with a crown volume of +5.5cc.

Silv-O-Lite hypereutectic pistons utilize an alloy with 15-16% silicon, offering increased strength and scuff resistance. This alloy also improves groove wear and resists crown cracking. It's important to note that hypereutectic aluminum has 15% less thermal expansion than conventional alloys, requiring a 40% increase in the listed top ring end gap. This piston is coated with an anti-friction dry lubricant, making it approximately .001 larger in diameter than uncoated pistons. Ensure you follow the 'Recommended Finished Bore Diameter' for proper installation.
