Manley Chevy LS Series 3.910in Bore 3.622in Stroke -4cc Flat Top Piston Set

Manley Performance is well-known for building robust engine components that professional builders trust. This piston set, designed for Chevy LS series engines, is a prime example of that commitment. It features a 3.910-inch bore and a 3.622-inch stroke, with a -4cc flat top dish, making it suitable for a wide range of performance builds where precise engine dimensions are critical.

These pistons are forged from domestic 2618 alloy, a material chosen for its exceptional strength and ability to handle the demands of high-performance engines. They come equipped with premium chrome moly wrist pins, and Manley's signature cam and barrel skirt profiles are incorporated to optimize power output while minimizing wear on cylinder walls. The ring lands and grooves are machined to exacting standards, which is key for achieving a solid ring seal and maximizing the power your engine can produce. Manley's unique machining process ensures the ring grooves are perfectly square to the skirt, a detail that contributes to overall engine reliability and performance.

This set includes eight pistons, each with a -4cc flat top dish. While these pistons are built for durability and performance, please note they are not CARB approved and cannot be shipped to California. For those building a high-performance LS engine, this Manley piston set offers a well-built foundation.
