About this part

Product Details

This set includes eight Manley Platinum Series pistons, designed for Small Block Chevy LS engines with a 4.130-inch bore. Each piston features an -18cc dish, which helps set your compression ratio for a specific build. These pistons are crafted from domestic 2618 alloy forgings, a material known for its strength and ability to handle high performance demands.

Manley's Platinum Series pistons incorporate proven cam and barrel skirt profiles. These profiles are designed to generate significant power while minimizing wear on your cylinder walls. The ring lands and grooves are machined to exacting standards, which is crucial for achieving a solid ring seal and maximizing the power output of your engine. For added durability, these pistons come with tool steel wrist pins, and Manley's unique fixturing process ensures the ring grooves are perfectly square to the piston skirt, a detail that matters for consistent performance.

These pistons are a popular choice among professional engine builders and tuners who need reliable components for high-performance applications. Please 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.
