Manley 592765C-8 Forged Piston Set Bore Dish Alloy - 4.065 10cc 2618

The Manley 592765C-8 forged piston set delivers race-proven performance for high-horsepower engine builds. Precision-machined from high-strength 2618 aluminum alloy, these pistons feature a -10cc dish design with a 4.065" bore and are engineered for 6.125" rod lengths with a 4.000" stroke. The 1.115" compression distance accommodates various compression ratios from 10.3:1 to 11.3:1 depending on chamber volume.

Key Specifications:

• Bore: 4.065 inches
• Compression Distance: 1.115 inches
• Pin Diameter: 0.927 inches
• Piston Weight: 432 grams (527 grams with pin)
• Ring Package: 1.5mm / 1.5mm / 3mm Total Seal
• Compression Ratios: 11.3:1 @ 64cc, 11:1 @ 66cc, 10.5:1 @ 70cc, 10.3:1 @ 72cc

Advanced Manufacturing Features:

• 2618 alloy construction provides maximum high-temperature strength and superior fatigue resistance for extreme performance applications
• Contour forging process optimizes strength-to-weight ratio without grain-interrupting internal milling
• Single-fixturing machining method ensures perfect ring groove to skirt squareness for maximum cylinder sealing and horsepower
• Proprietary multi-step top ring groove machining controls size, geometry, flatness, and surface finish
• Federal Form-Scan gauging validates precise skirt indexing and polarity
• Offset wrist pin design reduces piston slap during cold starts and improves overall performance
• Moly-coated skirts reduce friction and wear for extended service life

Includes: Tool steel wrist pins, roundwire locks, and pressure balance grooves standard with every set.

Note: Compression ratios calculated at 0.00" deck clearance, 9.240" deck height, and 0.042" compressed head gasket thickness.
