Manley Chevrolet Small Block Piston Set - 4.035in Bore 1.125in CH, -2.50 CC

Manley Performance is well-known for building strong, reliable engine components, and their Platinum Series pistons are a prime example. If you're building a Chevrolet Small Block engine and need pistons that can handle serious work, this set is designed for you. They feature a 4.035-inch bore, a 1.125-inch compression height, and a -2.50cc valve relief, making them a solid choice for many performance builds.

These pistons are forged from a domestic 2618 alloy, which is chosen for its exceptional strength and ability to perform under high stress. Manley also uses proven cam and barrel skirt profiles that help generate power while minimizing wear on your cylinder walls. The ring lands and grooves are machined to exacting standards, which is crucial for achieving a good seal and maximizing the power your engine makes. 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 piston skirt, a detail that matters for consistent performance.

When you're putting together a performance engine, the details make a big difference. This set includes the pistons and chrome moly wrist pins. Remember that these pistons are not CARB approved and cannot be shipped to California. Always refer to the manufacturer's installation instructions for proper fitment and assembly procedures.
