Manley 594230C-8 Forged Piston Set Bore Dish Alloy - 3.582 23cc 2618

The Manley 594230C-8 forged piston set is precision-engineered from high-strength 2618 alloy for maximum high-temperature strength and fatigue resistance in demanding performance applications. These lightweight pistons feature a 23cc dish design with a 3.582" bore, 1.220" compression distance, and are designed for 6.657" rod length with 4.165" stroke applications.

Key Specifications:

• Bore: 3.582 inches
• Compression Distance: 1.220 inches
• Piston Type: 23cc Dish
• Compression Ratios: 8.57:1 @ 42cc, 7.89:1 @ 51cc, 7.82:1 @ 52cc (calculated at 0.00 deck clearance, 9.240" deck height, and 0.042" compressed head gasket)
• Weight: 393g per piston (481g with pin)
• Ring Package: 1.5mm, 1.5mm, 3mm Total Seal configuration

Performance Features:

• 2618 aluminum alloy forging provides superior strength and thermal stability under extreme conditions
• Contour forgings optimize strength-to-weight ratio without grain-interrupting internal milling
• Single fixturing manufacturing process ensures perfect ring groove to skirt squareness for maximum horsepower
• Offset wrist pin design reduces piston slap for quieter operation and improved performance
• Moly-coated skirts reduce friction and wear
• Proprietary multi-step top ring groove machining guarantees optimal size, geometry, flatness, and finish
• Federal Form-Scan gauging validates ideal skirt indexing to pinhole and skirt-to-skirt polarity

Included Components:

• Roundwire locks
• Tool steel wrist pins
• Pressure balance grooves (standard feature)

Manley's precision pinhole machining ensures exact compression distance and precise lock ring groove spacing, size, and concentricity. The multi-step manufacturing process and quality control measures make these pistons ideal for high-performance street and racing applications where reliability and power are critical.
