Manley Chevy LS Series 4.030in Bore 1.115in CD -29cc Dish Platinum Series Pistons - Set of 8

If you're rebuilding or upgrading a Chevy LS engine for serious performance, a solid set of pistons is where you start. These Manley Platinum Series pistons are built for the demands of high-output builds, whether you're aiming for track days or just want a more powerful street machine. They're designed to fit a wide range of popular LS applications, including vehicles like the Chevrolet Camaro, Corvette, and Cadillac CTS.

Manley uses domestic 2618 alloy forgings for these pistons, which means they're strong and can handle the heat and pressure of performance engines. They feature proven cam and barrel skirt profiles that help reduce friction and wear on your cylinder walls, while also contributing to power gains. The ring lands and grooves are machined to strict standards, ensuring a tight seal for better compression and more power. Each set comes with premium chrome moly wrist pins, and Manley's unique manufacturing process ensures the ring grooves are perfectly square with the piston skirts for optimal performance.

This set includes eight pistons, each with a 4.030-inch bore and a -29cc dish volume, which is important for setting your compression ratio. They are designed as a direct replacement for many LS engines, but always double-check fitment for your specific vehicle. While these pistons are built for durability, remember they are not CARB approved and cannot be shipped to California.
