BUILD YOUR ENGINE USING THE STRONGEST PISTONS

These are the Manley Performance Platinum Series Piston Set. These pistons have been machined from lightweight 2618 construction, and they are ideal for those of you looking for a strong piston to sustain a high-horsepower or a high-boost build. These pistons feature an offset wrist pin design that is utilized for quiet start-ups and a perfect ring groove to skirt squareness that is achieved through Manley's "one fixturing" manufacturing method that assures maximum horsepower.

All pistons will come with moly coated skirts, as well as round wire locks, premium chrome moly wrist pins, and premium steel top ring sets, Napier-style second rings and higher tension oil rings from Total Seal.
