Manley Chevrolet Small Block Piston Set - 4.035in Bore 1.250in CH, -2.50 CC

Manley Performance is well-known for building serious engine components, and their Chevrolet Small Block piston sets are a prime example. If you're rebuilding a performance small block Chevy, these pistons are designed to handle the demands of a high-output engine. They feature a 4.035-inch bore and a 1.250-inch compression height, with a -2.50cc dish volume, making them suitable for a variety of performance builds.

These pistons are forged from domestic 2618 alloy, which is chosen for its superior strength and ability to withstand high temperatures and pressures common in performance engines. Manley also includes premium chrome moly wrist pins, known for their durability. The ring lands and grooves are machined to exacting standards, which helps ensure a better seal from your piston rings, leading to more power. You'll also find that these pistons have proven cam and barrel skirt profiles. This design helps generate power efficiently while also being designed to be gentle on your cylinder walls during operation. Manley uses unique fixturing that allows them to machine the skirt and ring grooves in a single setup, ensuring the ring grooves are perfectly square to the skirt for optimal performance.

This piston set is not CARB approved and cannot be shipped to California. It's important to note that these are performance parts, and professional installation is recommended to ensure proper fitment and function within your engine build.
