Manley Chevrolet Small Block 4.060in Bore 1.280in CH -4.00 CC Piston Set

Manley Performance has built a solid reputation for crafting robust engine components that professional builders trust. This piston set is a prime example, designed for Chevrolet Small Block engines and featuring their signature "Platinum Series" construction. If you're looking to rebuild or upgrade your engine's heart, these pistons offer a strong foundation for improved performance and lasting durability.

These pistons are forged from domestic 2618 alloy, a material chosen for its exceptional strength and ability to handle the demands of a high-performance engine. They come standard with premium chrome moly wrist pins, and for even greater durability, select part numbers offer upgrades to 9310 and Turbo Tuff/DLC alloys. Manley pays close attention to the details, machining exacting ring lands and grooves to ensure a tight seal for the piston rings, which translates directly into more power. The cam and barrel skirt profiles are carefully designed to generate power efficiently while minimizing wear on your cylinder walls. A unique aspect of Manley's manufacturing process is their fixturing, which allows for skirt turning and ring groove machining in a single operation. This ensures the ring grooves are perfectly square to the skirt, contributing to better ring seal and overall engine health.

This set is designed for a 4.060 inch bore with a 1.280 inch compression height and a -4.00 CC piston dish volume. Please note that this part is not CARB approved and cannot be shipped to California. It also carries a Prop 65 warning.
