Manley Chevy LT1 Direct Injected Series 4.065in Bore -2 cc Dish Extreme Duty Pistons

Manley Performance is well-known for making strong engine components, and these Direct Injected Series pistons are a prime example of that. If you're building a high-performance Chevy LT1 engine, especially one that uses direct injection, these pistons are built to handle the demands. They feature a 4.065-inch bore and a -2cc dish, which is a common setup for many performance builds.

These pistons are forged from domestic 2618 alloy, a material chosen for its exceptional strength and ability to withstand high cylinder pressures and temperatures. They come with premium chrome moly wrist pins, and Manley adheres to strict standards for the ring lands and grooves. This attention to detail ensures a better ring seal, which translates directly into more power and improved engine efficiency. The cam and barrel skirt profiles are designed to generate power while also being gentle on your cylinder walls, reducing wear over time. Manley's unique fixturing process allows them to machine the skirt and ring grooves in a single operation, ensuring they are perfectly square to each other for ultimate performance.

When you're building an engine where reliability and power are critical, using well-built components like these Manley pistons is essential. They are designed for serious engine builders and tuners who need parts that can perform under pressure. Please note that these pistons are not CARB approved and cannot be shipped to California.
