About this part

Product Details

Starting with domestic 2618 alloy forgings, these Manley Platinum Series pistons are built for serious performance in your Small Block Chevy LS engine. The 4.070-inch bore size and -18cc dish volume are key specifications for achieving specific compression ratios, especially when paired with the right cylinder heads and camshaft. These aren't just off-the-shelf parts; they're crafted with precision to handle the demands of high-output builds.

Manley's signature cam and barrel skirt profiles are designed to reduce friction and wear on your cylinder walls, contributing to both power gains and engine longevity. The exacting standards for ring lands and grooves ensure a tight seal, which is crucial for maximizing combustion efficiency and extracting every bit of power from your engine. Furthermore, their unique fixturing process allows for skirt turning and ring groove machining in a single operation, guaranteeing ultimate squareness between the piston skirt and the ring grooves. This attention to detail translates directly into better performance and reliability under stress.

Included with these pistons are premium chrome moly wrist pins, a solid foundation for durability. For those pushing the limits even further, Manley offers upgrades to 9310 and Turbo Tuff/DLC alloys for even greater strength. These pistons are a popular choice among professional engine builders and tuners who demand consistent results and robust performance from their LS engines. Please note that these pistons are not CARB approved and cannot be shipped to California.
