Manley Chevy LT1 Direct Injected Series 4.070in Bore -2 cc Dish Platinum Series Pistons

Starting with domestic 2618 alloy forgings, these Manley Platinum Series pistons are built for serious performance in your Chevy LT1 direct-injected engine. The 4.070-inch bore size and -2cc dish volume are specific to certain LT1 applications, making them a precise choice for rebuilding or upgrading your engine's core components. Professional engine builders trust Manley for their commitment to strength and durability, and this set is no exception.

Manley's design includes proven cam and barrel skirt profiles, which help generate substantial power while minimizing wear on your cylinder walls. They also pay close attention to the details that matter for sealing and longevity. 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. Furthermore, their unique fixturing process allows them to machine the skirt and ring grooves in one operation, ensuring the ring grooves stay perfectly square to the piston skirt. This attention to detail translates directly into a more reliable and powerful engine build.

Included with these pistons are premium chrome moly wrist pins, a key component for handling the stresses of engine operation. For those looking for even more durability, upgrades to 9310 or Turbo Tuff/DLC alloys are available for the wrist pins. This set is designed for a direct-injected LT1 engine, and while they offer superior performance, please note they are not CARB approved and cannot be shipped to California. Always refer to the manufacturer's installation instructions for proper assembly and break-in procedures.
