Manley Small Block Chevrolet LS Series 4.130in Bore/-11cc Dish Top Piston Set

Manley Performance is well-known for building robust engine components, and their LS Series pistons are a prime example of that commitment. If you're building a Small Block Chevrolet LS engine and need a reliable set of pistons, this 4.130-inch bore set with an -11cc dish top is designed to handle serious work. These aren't just off-the-shelf parts; they're crafted with the same attention to detail that professional engine builders rely on for both performance and durability.

What sets these pistons apart starts with the material: domestic 2618 alloy forgings. This alloy is chosen for its inherent strength, which is crucial when you're pushing an engine hard. They also feature proven cam and barrel skirt profiles, which are shaped to help generate power efficiently while also being designed to minimize wear on your cylinder walls. The ring lands and grooves are machined to strict standards, which is key for getting a good seal from your piston rings, leading to more power and better oil control. For added toughness, these pistons come standard with premium chrome moly wrist pins.

Manley's unique manufacturing process allows them to machine the skirt and ring grooves in one operation. This ensures that the ring grooves are perfectly square to the piston skirt, which is a detail that contributes to overall engine health and performance. Keep in mind that these pistons are not CARB approved and cannot be shipped to California. If you're looking for a well-built piston set for your LS engine build, these offer a solid foundation.
