About this part

Product Details

This set includes eight forged pistons for your Chevrolet LS engine, each measuring 4.005 inches in bore diameter. They are crafted from domestic 2618 alloy, a material known for its exceptional strength and performance under demanding conditions. These pistons are designed with proven cam and barrel skirt profiles, which help generate significant power while also being gentle on your cylinder walls. The set also comes standard with premium chrome moly wrist pins, adding to their durability.

Manley pays close attention to the details that matter for engine building. The ring lands and grooves are machined to strict standards, which is crucial for achieving a better ring seal and ultimately, more power. Their unique fixturing process allows for skirt turning and ring groove machining to be done in a single operation. This ensures ultimate squareness between the ring grooves and the piston skirt, a detail that professional engine builders and tuners rely on for superior performance and longevity.

These pistons are a solid option for anyone rebuilding or modifying their LS engine. Keep in mind that this part is not CARB approved and cannot be shipped to California. Always refer to the manufacturer's installation instructions for proper fitment and assembly procedures.
