Manley Chevy LT1 Direct Injected Series 4.065in Bore -12 cc Dish Platinum Series Pistons

When you're building a high-performance Chevy LT1 engine, especially one with direct injection, you need pistons that can handle the pressure and deliver consistent power. This set of Manley Platinum Series pistons is designed for that purpose. You get eight forged pistons, each with a 4.065-inch bore and a -12cc dish, ready to be installed in your engine build.

Manley uses domestic 2618 alloy forgings for these pistons, which are known for their strength and ability to perform under demanding conditions. They feature proven cam and barrel skirt profiles that help generate power while also being designed to be gentle on your cylinder walls during operation. The ring lands and grooves are machined to exacting standards, which is crucial for getting a good seal from your piston rings, ultimately leading to more power. These pistons also come with premium chrome moly wrist pins for added durability, and Manley's unique fixturing process ensures the ring grooves are perfectly square to the skirt, a detail that matters for proper sealing and performance.

This set is a solid choice for serious engine builders looking for reliable components. Keep in mind that these pistons are not CARB approved and cannot be shipped to California. Always refer to the manufacturer's installation instructions for proper fitment and assembly procedures.
