Description

Manley's Platinum Series pistons offer trouble-free installation, excellent reliability, and are designed for maximum horsepower. Made from 2618 high-strength material, these lightweight pistons feature a slightly thicker deck, ideal for high-horsepower applications. They ensure perfect ring groove to skirt squareness and include pressure balance grooves. The set comes with 2.300" length tool steel pins (96 Grams each), integral to the piston design, and spiral locks. A full banded skirt design enhances reliability. Designed for 23 Degree heads, they use .043" x .043" x 3mm ring grooves, achieving a 10.16:1 compression ratio with 64cc heads.
