Manley 594520C-8 Forged Piston Set Bore Alloy Dish - 3.572 2618 14cc

The Manley 594520C-8 is a precision-engineered forged piston designed for high-performance engine builds requiring exceptional strength and durability. Machined from high-strength 2618 aluminum alloy, this piston features a -14cc dish design with a 3.572" bore and delivers a 9.03:1 compression ratio at 51cc chamber volume. Each piston weighs 370 grams (458g with pin included) and utilizes a 1.220" compression distance optimized for 5.933" connecting rods and 3.543" stroke crankshafts.

Key Features:

• 2618 aluminum alloy construction provides maximum high-temperature strength and superior fatigue resistance for demanding applications
• Contour forging process delivers optimal strength-to-weight ratio without grain-interrupting internal milling
• Single-fixturing manufacturing method ensures perfect ring groove to skirt squareness for maximum horsepower and cylinder seal
• Proprietary multi-step top ring groove machining guarantees precise size, geometry, flatness, and surface finish
• 1.5mm, 1.5mm, 3mm Total Seal ring package for excellent compression control
• Moly-coated skirts reduce friction and wear during cold starts and high-load conditions
• Offset wrist pin design minimizes piston slap for quieter operation and improved performance
• Federal Form-Scan gauging validates ideal skirt indexing and polarity

Complete Package Includes:

• Round wire piston pin locks
• Tool steel wrist pins
• Pressure balance grooves (standard feature)
• Precision-machined pinhole with exact lock ring groove spacing and concentricity
