What is the purpose of the cam and barrel skirt profiles on these pistons?

The cam and barrel skirt profiles are designed to manage how the piston moves within the cylinder bore. This design helps to reduce wear on the cylinder walls while still allowing the piston to efficiently generate power during combustion.

What material are the wrist pins made from, and are there upgrade options?

These pistons come standard with premium Chrome Moly wrist pins, which offer good durability. Manley also offers upgrade options to 9310 and Turbo Tuff/DLC alloys for even greater strength in select part numbers.

Are these pistons compatible with all LS engine builds?

These pistons are designed for Chevrolet LS engines with a 4.010-inch bore and a -4.00 CC dish. It's important to confirm that these specifications match your engine's requirements and desired compression ratio before installation.

About this part

Product Details

Manley's 2618 alloy forgings are a hallmark of their performance pistons, offering a well-built foundation for serious engine builds. These pistons are specifically crafted for Chevrolet LS engines, featuring a 4.010-inch bore and a -4.00 CC dish volume, which is crucial for achieving your desired compression ratio. The 1.304-inch compression height also plays a key role in piston-to-valve clearance and overall engine geometry.

Beyond the robust 2618 alloy, Manley incorporates proven cam and barrel skirt profiles. This design choice helps manage piston rock within the cylinder bore, reducing wear on the cylinder walls while still allowing the piston to generate substantial power. The ring lands and grooves are machined to exacting standards, which is vital for achieving a solid ring seal. A good ring seal means less blow-by and more efficient combustion, directly translating to more power and better engine health. For added durability, these pistons come with premium Chrome Moly wrist pins, and Manley's unique fixturing process ensures the ring grooves are perfectly square to the skirt, a detail that matters for consistent performance under load.

When you're building an engine where every component needs to perform reliably, Manley pistons are a popular choice among professional engine builders and tuners. They are designed to handle the demands of high-performance applications, offering a blend of strength, precise machining, and thoughtful design features that contribute to both power output and longevity. Keep in mind that these pistons are not CARB approved and cannot be shipped to California.
