Manley Chevrolet LS Piston Set - 4.005in Bore 1.115in CH, -29.00 CC

When you're building a high-performance Chevrolet LS engine, you need parts you can trust. This set of Manley Performance pistons is built for serious work. You get eight forged pistons, each with a 4.005-inch bore and a -29.00cc dish volume, designed to work with a 1.115-inch compression height. These are the kind of components professional engine builders rely on for both raw power and long-term durability.

Manley uses domestic 2618 alloy forgings for these pistons, which means they're incredibly strong and can handle the demands of boosted or high-compression builds. The skirt profiles are carefully shaped to reduce friction and wear on your cylinder walls while still generating substantial power. They also pay close attention to the ring lands and grooves, ensuring a tight seal for better combustion efficiency and more horsepower. Each set includes chrome moly wrist pins, known for their toughness, and Manley's unique manufacturing process ensures the ring grooves are perfectly square to the piston skirts for optimal performance.

These pistons are designed to fit a wide range of Chevrolet LS engines found in vehicles like the Chevrolet Camaro, Corvette, and Pontiac GTO, among others. While they are built for performance, remember that this specific part is not CARB approved and cannot be shipped to California. If you're aiming for a robust LS build, these Manley pistons are a solid choice to form the foundation of your engine.
