Manley Small Block Chevy LS Series 4.010in Bore - 1.304in CD - -10 cc Dish Platinum Series Pistons

Manley Performance is well-known for making strong, reliable engine components for serious racers and builders. These Platinum Series pistons are a prime example, designed for Small Block Chevy LS engines with a 4.010-inch bore. If you're rebuilding your top end for more power or just need to replace worn-out pistons, these are a solid option that many professional engine builders trust.

What sets these pistons apart is the material and the machining. They're forged from 2618 alloy, a domestic material chosen for its superior strength and ability to handle the stresses of a performance engine. Manley also machines them with proven cam and barrel skirt profiles, which help reduce friction and wear on your cylinder walls while still making good power. The ring lands and grooves are held to exacting standards, which is crucial for getting a good seal from your piston rings, ultimately leading to more power and better efficiency. They also come with premium chrome moly wrist pins, and for some part numbers, you can even get upgrades to even tougher alloys.

When you're putting together a high-performance engine, the details matter. Manley's unique fixturing process ensures the ring grooves are perfectly square to the piston skirt, which is another detail that contributes to a better seal and more reliable performance. These pistons are a significant upgrade over stock, built to withstand the demands of modified LS engines. Please note that these pistons are not CARB approved and cannot be shipped to California.
