Manley 597505C-8 High-Performance Forged Engine Piston Alloy - 2618

The Manley 597505C-8 is a high-performance forged engine piston precision-machined from 2618 aluminum alloy for maximum high-temperature strength and fatigue resistance. Engineered for demanding applications, this piston delivers the ideal balance of lightweight construction and robust durability for long service life and maximum horsepower output.

Advanced Manufacturing Process:

• Contour forging provides optimal strength-to-weight ratio with no grain-interrupting internal milling
• Single-fixturing manufacturing method ensures perfect ring groove to skirt squareness for maximum cylinder wall sealing
• Proprietary multi-step top ring groove machining delivers precise groove size, geometry, flatness, and finish
• Federal Form-Scan gauging validates ideal skirt indexing to pinhole and skirt-to-skirt polarity
• Precision pinhole machining ensures exact compression distance and lock ring groove concentricity

Performance Features:

• Proven offset wrist pin design for quieter cold starts and improved performance
• 1.5mm, 1.5mm, 3mm Total Seal ring package for superior sealing
• Moly-coated skirts reduce friction and wear
• Integrated pressure balance groove included as standard
• Tool steel wrist pins and roundwire locks included with every set

Each piston is manufactured using advanced precision machining techniques to ensure consistent quality and performance. The 2618 alloy construction makes this piston ideal for high-performance street, racing, and forced induction applications where strength and heat resistance are critical.

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