About this part

Product Details

Manley Performance is well-known for building strong, reliable engine components, and their LS piston sets are a popular choice for serious engine builds. This particular set is designed for Chevrolet LS engines and features a 4.005-inch bore with a 1.304-inch compression height and an -18.00cc dish volume. These pistons are crafted from domestic 2618 alloy forgings, a material chosen for its exceptional strength and performance under demanding conditions, making them a solid foundation for a high-performance engine.

What sets these pistons apart is their advanced design and construction. They feature 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 a better seal from your piston rings, which translates directly to more power. Manley's unique fixturing process allows them to machine the skirt and ring grooves in a single operation, guaranteeing ultimate squareness between the ring groove and the skirt for optimal performance and durability. Each set includes premium chrome moly wrist pins, with options for upgrades to 9310 or Turbo Tuff/DLC alloys for even greater durability in extreme applications.

This piston set is a significant upgrade for anyone rebuilding or modifying their LS engine. It's important to note that these pistons are not CARB approved and cannot be shipped to California. Always refer to the manufacturer's installation instructions for proper fitment and assembly procedures.
