Manley 592805C-8 High-Performance Forged Engine Piston Alloy - 2618

The Manley 592805C-8 is a precision-engineered forged piston machined from high-strength 2618 aluminum alloy, designed to deliver maximum performance and durability in demanding engine applications. This lightweight yet robust piston features advanced manufacturing techniques that ensure optimal ring seal, reduced friction, and maximum horsepower output.

Premium 2618 Alloy Construction:

• High-temperature strength and superior fatigue resistance for extreme performance applications
• Contour forging design optimizes strength-to-weight ratio without grain-interrupting internal milling
• Lightweight design reduces reciprocating mass for improved throttle response and reduced engine stress

Precision Manufacturing Features:

• Single-fixturing machining process ensures perfect ring groove to skirt squareness for maximum 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 compression distance with precise lock ring groove spacing, size, and concentricity

Performance-Enhancing Design Elements:

• Offset wrist pin design for quieter cold starts and improved power delivery
• Moly-coated skirts reduce friction and provide excellent scuff resistance
• Pressure balance groove included for reduced ring flutter and improved oil control
• 1.5mm, 1.5mm, 3mm Total Seal ring package configuration for optimal sealing

Complete Kit Includes: Tool steel wrist pins, roundwire locks, and pressure balance grooves—no additional components required.

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