Manley Chevy LT1 Direct Injected Series 4.00in Stroke 4.065in B -20 cc Dish Platinum Series Pistons

Manley Performance is well-known for making strong engine components, and their Platinum Series pistons are a prime example of that. If you're building a high-performance Chevy LT1 engine, especially one with direct injection, these pistons are designed to handle the demands. They feature a -20cc dish, a 4.00-inch stroke, and a 4.065-inch bore size, making them a solid choice for serious engine builds.

These pistons are forged from domestic 2618 alloy, which is chosen for its superior strength and ability to perform under high stress. Manley also uses proven cam and barrel skirt profiles that help generate power while being easier on your cylinder walls. The ring lands and grooves are machined to exacting standards, which is crucial for getting a good seal from your piston rings and maximizing power output. They also come with tool steel wrist pins, and Manley's unique fixturing process ensures the ring grooves are perfectly square to the skirt, contributing to overall engine health and performance.

When you're putting together a serious engine, the details matter. These Manley Platinum Series pistons are built with those details in mind, from the material choice to the precise machining. Keep in mind that these are not CARB approved and cannot be shipped to California. For builds outside of California, they represent a well-built option for those looking for reliable performance.
