Manley Chevrolet SB LS 3.622in Stroke / 18cc Dish / 4.070in Bore Platinum Series Dish Pistons

Manley Performance is well-known for building robust engine components, and their Platinum Series pistons are a prime example of that commitment. If you're building a Chevrolet SB LS engine and need a reliable set of pistons, these are designed to handle serious work. They feature a 3.622-inch stroke, an 18cc dish to help set your compression ratio, and a 4.070-inch bore size, making them a solid choice for many LS builds.

These pistons are forged from 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 being easier on your cylinder walls. The ring lands and grooves are machined to exacting standards, which is crucial for getting a good seal from your piston rings, ultimately leading to more power and better engine efficiency. Each set comes standard with premium chrome moly wrist pins, and Manley's unique fixturing process ensures the ring grooves are perfectly square to the skirt, a detail that matters for long-term durability and performance.

When you're putting together a performance engine, the details make a big difference. These pistons are a popular choice among professional engine builders and tuners for a reason. Keep in mind that these are not CARB approved and cannot be shipped to California. Always refer to the manufacturer's installation instructions for proper fitment and assembly procedures.
