About this part

Product Details

If you're building a high-performance Chevrolet LS engine, this Manley Piston Set is a solid choice. These pistons are designed for a 4.065-inch bore and feature a -18.00 CC dish, which is important for setting your compression ratio. Manley is a well-known name among professional engine builders, and these are part of their "Platinum Series," meaning they're built for serious performance and durability.

What sets these pistons apart is the material and the machining. They're forged from domestic 2618 alloy, which is known for being strong and handling high loads without failing. The skirt profiles are carefully shaped to help generate power while also being gentle on your cylinder walls, reducing wear over time. Manley also pays close attention to the ring lands and grooves, ensuring a tight seal for your piston rings. This precise machining helps get more power out of every combustion cycle and contributes to the overall longevity of your engine build. They also come with tool steel wrist pins, which are robust enough for demanding applications.

When you're putting together an engine like this, every component matters. These pistons are designed to work with specific ring sets and are a critical part of achieving your desired compression and performance goals. Because they are a performance part, it's always a good idea to consult with your engine builder or refer to Manley's installation guidelines to ensure everything is set up correctly for your specific application.
