Manley Chevy LS Series 4.001in Bore 1.115in CH -10cc Platinum Series Pistons - Set of 8

If you're building or rebuilding a Chevy LS engine, these Manley Platinum Series pistons are a solid choice for serious performance. They're designed for a 4.001-inch bore and feature a -10cc dish volume, making them suitable for a wide range of LS applications, including vehicles like the 1997-2008 Chevrolet Corvette, 2004-2007 Cadillac CTS, and 1998-2002 Pontiac Firebird.

Manley uses domestic 2618 alloy forgings for these pistons, which means they're exceptionally strong and can handle the demands of high-performance engines. The pistons also come with tool steel wrist pins and feature cam and barrel skirt profiles. These profiles are carefully shaped to help the piston generate power efficiently while also being gentle on your cylinder walls, which helps with longevity. Manley also pays close attention to the ring lands and grooves, ensuring a tight seal for better compression and more power. They even use a unique fixturing process that machines the skirt and ring grooves in one go, ensuring they are perfectly square to each other for optimal ring seal.

This set includes eight pistons, the tool steel wrist pins, and a moly skirt coating for reduced friction. While these pistons are built for performance, remember they are not CARB approved and cannot be shipped to California. Always refer to the manufacturer's installation instructions for proper fitment and assembly details.
