Manley Chevy LS Series 3.905in Bore 3.622in Stroke -4cc Flat Top Piston Set

When you're building a serious LS engine, you need pistons that can handle the stress and deliver reliable performance. This set from Manley Performance gives you exactly that. You get eight forged pistons, each designed with a 3.905-inch bore and a 3.622-inch stroke. They feature a -4cc flat top dish, which is a common configuration for many LS engine builds, especially those looking for a specific compression ratio with typical LS cylinder heads. These pistons are built for durability and performance, making them a solid choice for engine overhauls or performance upgrades across a range of vehicles like the Chevrolet Camaro, Corvette, and Pontiac Firebird.

Manley is known for making well-built engine components, and these pistons are no exception. They are forged from high-strength aluminum alloy, which is much stronger and more durable than cast aluminum. This forging process creates a denser, more uniform grain structure, allowing the pistons to withstand higher cylinder pressures and temperatures without deforming or failing. The flat top design is versatile and works well with various cylinder head combinations to achieve your target compression ratio. This set is designed to fit a wide array of LS-based engines, ensuring you have the right components for your project, whether it's a street car, a track car, or a custom build.

This piston set is a critical component for anyone rebuilding or significantly upgrading their LS engine. It's important to note that these pistons are not CARB approved and cannot be shipped to California. Always refer to your engine builder's specifications and the manufacturer's installation instructions to ensure proper fitment and assembly. Proper ring gap setting and piston-to-wall clearance are crucial for the longevity and performance of these high-performance pistons.
