Product Details

If you're building a high-performance Chevrolet LS engine, these flat-top pistons from Manley Performance are a solid choice. They're designed for a 4.030 inch bore and a 4 inch stroke, with a -4cc dish volume, making them suitable for a wide range of LS applications. You'll find these pistons used in everything from classic Camaros and Firebirds to Corvettes and Cadillac CTS models. Manley has a reputation for making well-built internal engine components, and these pistons are no exception.

What sets these pistons apart is the material and the manufacturing process. They're forged from 2618 alloy, which is known for its strength and ability to handle high temperatures and pressures found in performance engines. Manley also includes tool steel wrist pins, which are strong enough for demanding use. The skirt profiles are carefully designed to reduce friction and wear on the cylinder walls, while the ring lands and grooves are machined to very tight tolerances. This attention to detail helps ensure a good seal for maximum power output. The unique fixturing Manley uses allows them to machine the skirt and the ring grooves in the same setup, which helps keep everything square and true.

When you're putting together a serious engine build, the internal components are critical. These Manley pistons are built to handle the stress of performance driving and racing. They are a popular choice among professional engine builders for their reliability and performance. Keep in mind that these pistons are not CARB approved and cannot be shipped to California. You'll also want to refer to the manufacturer's installation instructions for specific details on ring gap, piston-to-wall clearance, and assembly.
