What makes the 2618 alloy forging beneficial for these pistons?

The domestic 2618 alloy forging is chosen for its superior strength and performance characteristics. This material is well-suited to handle the high stresses and temperatures found in performance LS engines, contributing to overall durability.

What is the purpose of the cam and barrel skirt profiles?

These specific skirt profiles are designed to optimize piston movement within the cylinder. They help generate substantial power by ensuring efficient combustion while also being gentle on the cylinder walls, which reduces wear and prolongs engine life.

Are these pistons compatible with all LS engine builds?

These pistons are designed for Small Block Chevrolet LS Series engines with a 4.075-inch bore and 4-inch stroke. While they are a popular choice for performance builds, it's crucial to ensure they match your specific engine's requirements and desired compression ratio.

About this part

Product Details

These Manley "Platinum Series" pistons start with domestic 2618 alloy forgings, a material chosen for its exceptional strength and performance under high stress. They are specifically designed for Small Block Chevrolet LS Series engines, featuring a -29cc dish to accommodate your build's compression ratio needs, a 4.075-inch bore, and a 4-inch stroke. When you're building a performance engine, the foundation matters, and these pistons are built to be that solid foundation.

Manley's design incorporates proven cam and barrel skirt profiles, which help generate substantial power while also being gentle on your cylinder walls, reducing wear over time. The ring lands and grooves are machined to exacting standards, ensuring an enhanced ring seal which translates directly to more power and better efficiency. For added durability, these pistons come standard with premium chrome moly wrist pins, and Manley's unique fixturing process allows for skirt turning and ring groove machining in a single operation. This ensures ultimate squareness between the ring grooves and the skirt, a critical detail for proper sealing and longevity.

If you're rebuilding a performance LS engine, whether for street use or track duty, these Manley pistons are a popular choice among professional engine builders and tuners. They are well-built and designed to handle the demands of a high-performance application. Please note that these pistons are not CARB approved and cannot be shipped to California.
