Manley Small Block Chevrolet LS Series 4.130in Bore 1.115in Comp -18cc Dish Piston Set -E/D

If you're rebuilding the heart of your Small Block Chevrolet LS engine, a solid set of pistons is crucial for performance and reliability. This Manley Performance piston set is built for those who demand more from their engine, whether for street performance or track use. They feature a -18cc dish, designed to work with specific compression ratios for your build.

Manley uses domestic 2618 alloy forgings for these pistons, which are known for their exceptional strength and ability to handle high performance demands. The pistons also feature proven cam and barrel skirt profiles, which help reduce friction and wear on your cylinder walls while still generating power. You'll also find exacting standards in the ring lands and grooves, which are critical for achieving a good seal and maximizing the power your engine makes. Each set includes tool steel wrist pins, and some configurations offer upgrades for even more durability.

These pistons are a popular choice among professional engine builders because of their robust construction and the attention to detail in their machining. Manley's unique fixturing process allows them to machine the skirt and ring grooves in one operation, ensuring they are perfectly square to each other. This level of precision contributes to better ring seal and overall engine performance. Keep in mind that these are not CARB approved and cannot be shipped to California.
