About this part

Product Details

If you're building a high-performance Chevrolet small block engine, Manley's Platinum Series pistons are a solid choice. These pistons are forged from 2618 alloy, a strong material known for its ability to handle the stresses of performance applications. They feature proven cam and barrel skirt profiles designed to generate power while minimizing wear on your cylinder walls. The precise machining of the ring lands and grooves is critical for a good seal, which translates directly into more power from your engine.

Manley uses domestic 2618 alloy forgings for these pistons, ensuring they have the strength needed for demanding builds. They come standard with chrome moly wrist pins, and for even greater durability, some part numbers offer upgrades to 9310 or Turbo Tuff/DLC alloys. The skirt profiles are carefully machined to be gentle on the cylinder walls, and Manley's unique fixturing allows them to machine the skirt and ring grooves in a single operation. This ensures the ring grooves are perfectly square to the skirt, which is essential for optimal ring seal and engine performance.

This set is designed for a 4.035-inch bore with a -4.00 CC dish, suitable for specific compression ratio targets. Remember that these pistons are not CARB approved and cannot be shipped to California. For serious engine builds, Manley pistons are a popular choice among professional engine builders and tuners who need reliable performance and durability.
