The Manley Platinum Series forged piston set for Chevrolet small block has a 4.060-inch bore, 1.280-inch compression height and -4.00 cc crown volume for tailored compression requirements. Built from domestic 2618 alloy forgings with tool-steel wrist pins, the pistons pair cam-and-barrel skirt profiles with exact ring lands and grooves. Unique fixturing yields consistent groove-to-skirt squareness, and select SKUs include moly skirt coatings to reduce friction in critical areas.
