Manley Big Block Chevrolet LS Series 4.075in Bore 4in Stroke -10cc Dish Platinum Series Piston Set

This set includes eight forged pistons, each designed for Big Block Chevrolet LS series engines. You get pistons with a 4.075-inch bore and a 4-inch stroke, featuring a -10cc dish volume. These are Manley's Platinum Series, which means they're built with domestic 2618 alloy forgings for serious strength and performance. Professional engine builders and tuners often choose Manley because they know these pistons can handle demanding builds.

What sets these pistons apart is the attention to detail in their construction. They use proven cam and barrel skirt profiles, which help generate good power while being easier on your cylinder walls. The ring lands and grooves are machined to very strict standards, which is key for getting a solid seal from your piston rings and making more power. Manley also uses a unique fixturing process that allows them to machine the skirt and cut the ring grooves in one go. This ensures the ring grooves are perfectly square to the piston skirt, which is critical for proper ring function and engine longevity.

Each piston set comes standard with tool steel wrist pins for added durability. If you're building a high-performance engine and need a well-built, reliable piston, this set is a solid option. Keep in mind these are not CARB approved and cannot be shipped to California.
