Product Details

If you're rebuilding the heart of your Chevrolet LS engine for serious performance, a set of high-strength pistons is where you start. These Manley "Platinum Series" pistons are built for demanding builds, offering a robust foundation for boosted or naturally aspirated setups. They feature a flat top design with a -5cc volume, designed to work with a 4.125 inch bore and a 4.000 inch stroke, making them suitable for a wide range of popular LS applications like the Chevrolet Camaro, Corvette, and Pontiac GTO.

Manley uses domestic 2618 alloy forgings, which are known for their exceptional strength and ability to handle high cylinder pressures and temperatures without deforming. This is crucial for durability in performance engines. The pistons also come with premium chrome moly wrist pins, and Manley's unique fixturing process ensures the ring lands and skirt machining are perfectly square to each other. This attention to detail helps achieve a better ring seal, which translates directly into more power and improved engine efficiency. The cam and barrel skirt profiles are also carefully engineered to reduce friction and wear on your cylinder walls, even under aggressive use.

This set includes eight pistons, along with the necessary chrome moly wrist pins. When building a performance LS engine, starting with well-made, strong internal components like these Manley pistons is key to achieving your power goals and ensuring the longevity of your build. Remember to consult your engine builder or service manual for specific installation procedures and recommended clearances.
