About this part

Product Details

Built with domestic 2618 alloy forgings, these Manley pistons are a solid choice for anyone rebuilding or upgrading their Chevrolet 5.3L LS Gen III engine. The 3.785-inch bore size and -7.00cc dish volume are specific to certain LS applications, and the 1.115-inch compression height is crucial for achieving the correct compression ratio with your chosen cylinder heads and crankshaft.

Manley uses proven cam and barrel skirt profiles on these pistons. This design helps generate power efficiently while also being gentle on your cylinder walls, which is important for long-term engine health. They also pay close attention to the ring lands and grooves, machining them to strict standards to ensure a better seal from your piston rings, translating directly into more power. The pistons come with chrome moly wrist pins, and Manley's unique fixturing process allows them to machine the skirt and ring grooves in one operation. This ensures the ring grooves are perfectly square to the skirt, which further enhances the ring seal and overall performance.

This set includes eight pistons, eight wrist pins, and eight sets of locks. Please note that these pistons are not CARB approved and cannot be shipped to California. It's always a good idea to consult with your engine builder or refer to Manley's technical documentation for specific installation details and recommended components to achieve your desired build goals.
