About this part

Product Details

When you're building a serious Small Block Chevrolet LS engine, you need pistons that can handle the stress and deliver consistent power. This set from Manley Performance includes eight forged pistons, each featuring a dished top designed for a 4.125-inch bore. These aren't just any pistons; they're part of Manley's "Platinum Series," which means they're built with the kind of attention to detail that professional engine builders trust for high-performance applications.

What sets these pistons apart is the material and the machining. They're forged from domestic 2618 alloy, a material known for its strength and ability to withstand high temperatures and pressures. You also get tool steel wrist pins, which are crucial for connecting the piston to the connecting rod reliably. Manley also applies cam and barrel skirt profiles, which help the piston move smoothly within the cylinder walls, reducing wear and improving power. The ring lands and grooves are machined to very strict standards, ensuring a tight seal with your piston rings for better compression and more power. Plus, Manley uses a unique fixturing process that allows them to machine the skirt and ring grooves in one go, making sure they're perfectly square to each other.

This piston set is designed to fit a wide range of Small Block Chevrolet LS engines found in vehicles like the Chevrolet Camaro, Pontiac Firebird, and Cadillac CTS. If you're looking to rebuild or upgrade your engine for more power and durability, these Manley pistons are a solid choice. Keep in mind that these are not CARB approved and cannot be shipped to California.
