• 2618 Alloy Forgings: We use domestic 2618 alloy forgings, ensuring superior strength and performance.
• Cam and Barrel Profiles: Our pistons boast cam and barrel (skirt) profiles that generate substantial power while being gentle on cylinder walls.
• Chrome Moly Wrist Pins: Premium Chrome Moly wrist pins come standard with our Standard Series Pistons. For select SKUs, we offer wrist pin upgrades to 9310 and Turbo Tuff/DLC alloys, providing additional durability.
• Exacting Ring Lands and Grooves: We adhere to strict standards for piston ring lands and grooves, resulting in enhanced ring seal and more power.
• Unique Fixturing: Manley's unique fixturing allows for skirt turning and ring groove machining in a single operation, ensuring ultimate ring groove to skirt squareness.

Note for Pistons, Rings, Rotors, Rods and engine internals

Unless otherwise specified, some brands supply brake rotors, pistons, strut mounts, rods and rings separately. In some cases, titles may indicate plural, or 'set' - eg the term “ring set” often refers to the rings for a single piston only.
