About this part

Product Details

When you're rebuilding the top end of your Chevrolet LS engine for serious performance, choosing the right pistons is critical. This Manley Performance piston set is built for those who demand strength and reliability, whether you're building a race motor or a high-output street machine. They feature a 4.065-inch bore size and a -20.00cc dish, which is a common configuration for many naturally aspirated and forced induction LS builds.

Manley uses domestic 2618 alloy forgings for these pistons, a material known for its exceptional strength and ability to withstand high cylinder pressures and temperatures. The pistons also feature proven cam and barrel skirt profiles, designed to generate power efficiently while minimizing wear on your cylinder walls. You'll also find exacting standards applied to the ring lands and grooves, which is key for achieving a solid ring seal and maximizing the power your engine makes. The included tool steel wrist pins are also well-built for durability under stress.

This set is a popular choice among professional engine builders because of the attention to detail in their manufacturing. Manley's unique fixturing process allows them to machine the skirt and cut the ring grooves in one operation, ensuring the ring grooves are perfectly square to the piston skirt. This level of precision contributes to better overall engine performance and longevity. Please note that these pistons are not CARB approved and cannot be shipped to California.
