Manley 592830C-8 Forged Alloy Performance Engine Piston - 2618

The Manley 592830C-8 is a precision-engineered performance piston machined from high-strength 2618 aluminum alloy, designed to deliver exceptional durability and maximum horsepower in demanding applications. This lightweight yet robust piston features an advanced offset wrist pin design, moly-coated skirts for reduced friction, and a proven 1.5mm, 1.5mm, 3mm Total Seal ring package for superior sealing and performance.

Key Features:

• 2618 aluminum alloy construction provides maximum high-temperature strength and superior fatigue resistance
• Contour forging delivers optimum strength-to-weight ratio without grain-interrupting internal milling
• One-fixturing manufacturing method ensures perfect ring groove to skirt squareness for maximum cylinder wall contact
• Proprietary multi-step top ring groove machining guarantees ideal size, geometry, flatness, and finish
• Federal Form-Scan gauging validates precise skirt indexing and polarity
• Offset wrist pin design reduces piston noise during cold starts and enhances overall performance
• Moly-coated skirts included for reduced friction and extended service life
• Pressure balance groove designed to equalize crankcase pressure
• Complete set includes roundwire locks, tool steel wrist pins, and all necessary hardware

Each piston undergoes precise pinhole machining to maintain exact compression distance and optimal lock ring groove spacing, size, and concentricity. The advanced manufacturing process ensures consistent quality and performance across all applications.

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