About this part

Product Details

If you're building a high-performance Chevrolet LS engine, this set of Manley forged pistons is a solid choice. These pistons are designed for a 4.005-inch bore and feature a -31.00 CC dish, which is crucial for setting your compression ratio. Manley uses domestic 2618 alloy forgings, known for their strength and ability to handle the demands of performance builds. They also come with premium chrome moly wrist pins, adding to their durability.

What really sets these pistons apart is the attention to detail in their design and manufacturing. They feature proven cam and barrel skirt profiles, which help generate power while being easier on your cylinder walls. Manley also machines the ring lands and grooves to very strict standards, ensuring a better seal for your piston rings, which translates directly to more power. Their unique fixturing process allows them to machine the skirt and ring grooves in one operation, making sure the ring grooves are perfectly square to the skirt. This level of precision is what professional engine builders rely on for consistent performance and longevity.

This set includes eight pistons, eight wrist pins, and eight sets of locks. Remember that these pistons are not CARB approved and cannot be shipped to California. For a complete build, you'll want to ensure you have the correct piston rings and consider the appropriate cylinder wall preparation for these forged components.
