Manley 597500C-8 High-Performance Forged Engine Piston Alloy - 2618

The Manley 597500C-8 is a high-performance forged engine piston precision-machined from 2618 alloy for maximum high-temperature strength and fatigue resistance. Engineered for demanding applications, this piston delivers exceptional durability while maintaining an optimized strength-to-weight ratio for maximum horsepower output.

Premium Construction Features:

• 2618 aluminum alloy forging provides superior high-temperature strength and fatigue resistance compared to cast or hypereutectic pistons
• Contour forging design balances strength and weight without grain-interrupting internal milling
• Moly-coated skirts reduce friction and protect against scuffing during cold starts
• Offset wrist pin design minimizes piston rock for quieter operation and improved performance
• Tool steel wrist pins and round wire locks included

Precision Manufacturing Process:

• Single-fixturing machining method ensures perfect ring groove to skirt squareness for optimal cylinder wall seal
• Proprietary multi-step top ring groove machining controls groove size, geometry, flatness, and surface finish
• Federal Form-Scan gauging validates precise skirt indexing to pinhole and skirt-to-skirt polarity
• Exact pinhole machining delivers precise compression distance and lock ring groove concentricity

Included Components:

• 1.5mm, 1.5mm, 3mm Total Seal ring package
• Pressure balance groove (standard on all Manley pistons)
• Tool steel wrist pins
• Round wire locks

Ideal for high-performance street, racing, and forced induction applications where durability and power output are critical. Manley's proven engineering and manufacturing processes ensure consistent quality and long service life under extreme conditions.
