Manley Chevy LT1 Direct Injected Series 4.00in Stroke 4.065in B -10 cc Dish Platinum Series Pistons

Manley Performance is well-known for making strong engine components that professional builders trust. If you're working on a Chevy LT1 Direct Injected engine and need a solid set of pistons, their Platinum Series is a great place to start. These pistons are built for a 4.00-inch stroke and a 4.065-inch bore, featuring a -10cc dish that's common for many performance builds.

What sets these pistons apart is the material: they use domestic 2618 alloy forgings, which are known for their superior strength and ability to handle high performance demands. You'll also find proven cam and barrel skirt profiles designed to make good power while being easier on your cylinder walls. Manley also pays close attention to the details, like exacting standards for ring lands and grooves to ensure a better seal, and their unique fixturing process helps maintain squareness between the ring grooves and the skirt. These pistons come standard with tool steel wrist pins, and for some part numbers, you can even get upgrades to even tougher alloys like 9310 or Turbo Tuff/DLC for added durability.

When you're building an engine where reliability and performance are key, using components like these Manley Platinum Series pistons can make a significant difference. They are designed to work with direct-injected LT1 engines, and while they are not CARB approved and cannot be shipped to California, they represent a well-built option for serious engine builds.
