Manley Chevrolet LS Piston Set - 4.185in Bore 1.115in CH, -18.00 CC

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 high-performance Chevrolet LS engine, these pistons are designed to handle serious power. They feature a 4.185-inch bore and a -18.00 CC dish, making them suitable for specific compression ratio targets in performance builds.

These pistons are forged from domestic 2618 alloy, a material chosen for its exceptional strength and ability to withstand the stresses of high-performance engines. Manley uses proven cam and barrel skirt profiles, which help generate power efficiently while also being gentle on your cylinder walls, reducing wear over time. The ring lands and grooves are machined to exacting standards, ensuring a tight seal for improved combustion efficiency and more power output. For added durability, these pistons come with tool steel wrist pins, and Manley's unique fixturing process ensures the ring grooves are perfectly square to the skirt, a critical detail for proper sealing and longevity.

This set includes eight pistons, each with a 4.185-inch bore and a 1.115-inch compression height. Please note that these pistons are not CARB approved and cannot be shipped to California. If you're aiming for a powerful and durable LS engine build, these Manley pistons are a solid choice.
