About this part

Product Details

If you're rebuilding the engine in your Chevy LT1 with direct injection, you're likely looking for pistons that can handle serious power. These Extreme Duty pistons from Manley Performance are built for just that. They feature a -12cc dish, a 4.080-inch bore, and a 3.622-inch stroke, making them a solid choice for pushing the limits of your engine.

Manley uses domestic 2618 alloy forgings, which are known for their exceptional strength and ability to perform under high stress. The pistons also come with premium chrome moly wrist pins, and Manley's unique fixturing process ensures the ring grooves are perfectly square to the skirt. This attention to detail helps achieve a better ring seal, which translates directly to more power and improved engine efficiency. The cam and barrel skirt profiles are designed to be effective at generating power while also being gentle on your cylinder walls, which is crucial for longevity in a performance build.

These pistons are a popular choice among professional engine builders and tuners who demand reliability and performance. Keep in mind that these are not CARB approved and cannot be shipped to California. For a high-performance build, you'll want to ensure you have all the necessary supporting components and follow the manufacturer's installation guidelines carefully.
