About this part

Product Details

Manley Performance is well-known for building robust engine components, and their Chevrolet LS Piston Set is a prime example of that commitment. If you're building a high-performance LS engine, these pistons are designed to handle the demands of serious tuners and engine builders. They feature a 3.905-inch bore and a -18.00cc dish, making them suitable for specific compression ratio targets in your build.

These pistons are forged from domestic 2618 alloy, which is chosen for its superior strength and ability to perform under high stress. The skirt profiles are a proven cam and barrel design, engineered to generate substantial power while also being gentle on your cylinder walls, which helps with longevity. Manley also pays close attention to the details, adhering to strict standards for the ring lands and grooves. This precision ensures an enhanced ring seal, which directly translates to more power from your engine. The included wrist pins are premium Chrome Moly, and for some part numbers, upgrades to even more durable alloys are available.

What sets Manley apart is their unique fixturing process. This allows them to machine the skirt turning and ring groove operations in a single setup. This ensures ultimate squareness between the ring grooves and the skirt, a critical detail for proper ring seal and engine health. These pistons are not CARB approved and cannot be shipped to California.
