About this part

Product Details

Starting with the 2618 alloy forgings, these Manley pistons are built for serious performance. This domestic alloy is known for its strength, making it a solid choice when you're pushing your engine hard. They're designed with proven cam and barrel skirt profiles, which help generate power while also being considerate of your cylinder walls during operation. This attention to detail means you get a piston that works hard without causing unnecessary wear.

Manley also pays close attention to the details that matter for sealing and power. The ring lands and grooves are machined to exacting standards, which helps ensure a better seal for the rings. This improved seal means more consistent compression and ultimately, more power from your engine. The pistons come with premium chrome moly wrist pins, and for some applications, Manley offers upgrades to even stronger alloys like 9310 or Turbo Tuff/DLC for added durability. The unique fixturing Manley uses allows them to machine the skirt and ring grooves in one go, ensuring they are perfectly square to each other. This level of precision is what separates a good piston from a great one, especially when you're building a high-performance engine.

This set includes the pistons, rings, and wrist pins, ready for installation. Keep in mind that these pistons are not CARB approved and cannot be shipped to California. Always refer to the manufacturer's installation instructions for proper fitment and assembly procedures.
