Manley 597405C-8 High-Performance Forged Engine Piston Alloy - 2618

The Manley 597405C-8 is a precision-engineered forged piston machined from high-strength 2618 aluminum alloy, designed to deliver maximum performance and durability in high-performance engine builds. This lightweight yet robust piston features advanced manufacturing techniques that ensure perfect ring groove to skirt squareness, maximizing horsepower and compression efficiency.

Key Features:

• 2618 Alloy Construction: Provides superior high-temperature strength and fatigue resistance for demanding applications
• One-Fixturing Manufacturing: All final turning performed in a single setup ensures complete squareness of rings to cylinder wall
• Total Seal Ring Package: Includes proven 1.5mm, 1.5mm, 3mm ring configuration for optimal sealing
• Offset Wrist Pin Design: Reduces piston rock for quieter operation and improved performance
• Moly-Coated Skirts: Factory-applied coating reduces friction and wear
• Contour Forging: Optimizes strength-to-weight ratio without grain-interrupting internal milling
• Precision Pinhole Machining: Ensures exact compression distance and lock ring groove concentricity
• Pressure Balance Groove: Included as standard for improved ring seal and reduced blow-by

Complete Kit Includes:

• Forged 2618 alloy piston
• Roundwire locks
• Tool steel wrist pins
• Total Seal ring package

Manley's proprietary multi-step top ring groove machining process and Federal Form-Scan gauging validation ensure ideal skirt indexing and perfect polarity. Each piston undergoes rigorous quality control to guarantee precise dimensions and optimal performance in high-output engines.

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