Manley Chevrolet LS Piston Set - 4.125in Bore 1.065in CH, -20.00 CC

When you're building a high-performance Chevrolet LS engine, the pistons are a critical component. This set from Manley Performance includes eight forged pistons, each designed for a 4.125-inch bore with a 1.065-inch compression height and a -20.00cc dish. These pistons are crafted from domestic 2618 alloy forgings, a material chosen for its exceptional strength and ability to handle the demands of performance engines. You'll also find that they come standard with premium chrome moly wrist pins, which are known for their durability.

Manley puts a lot of thought into the profiles of these pistons. They feature proven cam and barrel skirt designs that help generate significant power while also being designed to be gentle on your cylinder walls, reducing wear over time. The ring lands and grooves are machined to exacting standards, which is key for achieving a better ring seal. A better ring seal means more efficient combustion and ultimately, more power from your engine. Manley's unique fixturing process allows them to machine the skirt and ring grooves in a single operation, ensuring the ring grooves are perfectly square to the skirt for optimal performance.

This piston set is a solid option for serious engine builders and tuners looking for reliable components for their LS engine builds. While these pistons are not CARB approved and cannot be shipped to California, they represent a well-built choice for many performance applications. Remember to consult your engine build specifications and manufacturer's instructions for proper installation and compatibility with other components.
