Manley Kit Chevrolet Small Block Platinum Series Piston Set - 4.125 in. Bore 1.0 in. CH -20.0 CC

Manley Performance is well-known for making strong engine components, and their Platinum Series piston set is a prime example. If you're building or rebuilding a Chevrolet Small Block engine and need pistons that can handle serious work, this set is designed for you. These aren't just any pistons; they're forged from a 2618 alloy, a material chosen for its exceptional strength and ability to perform under high stress, making them a solid choice for performance builds.

What sets these pistons apart is the attention to detail in their design and manufacturing. They feature proven cam and barrel skirt profiles, which help them run smoothly against cylinder walls while still generating significant power. The ring lands and grooves are machined to very strict standards, which is crucial for getting a good seal from your piston rings – that means more power and better efficiency. They also come with tool steel wrist pins for added durability, and Manley's unique fixturing process ensures the ring grooves are perfectly square to the skirt, a detail that matters for consistent performance and longevity.

This set is specifically for a 4.125-inch bore with a -20.0cc dish, which is important to know for calculating your engine's compression ratio. When you're putting together a high-performance engine, using well-made components like these Manley pistons is key to achieving your goals. Remember, these pistons are not CARB approved and cannot be shipped to California.
