Manley Chevrolet LS Piston Set - 4.130in Bore 1.115in CH, -29.00 CC

When you're rebuilding the heart of your Chevrolet LS engine, you want parts you can trust. This set includes eight forged pistons, each designed to meet the demands of high-performance builds. They feature a 4.130-inch bore, a 1.115-inch compression height, and a -29.00cc dish volume, making them suitable for specific compression ratio targets in your engine build.

Manley uses domestic 2618 alloy forgings for these pistons, which offers a strong foundation for durability and performance. The pistons come standard with chrome moly wrist pins, known for their toughness. Manley also pays close attention to the ring lands and grooves, holding them to strict standards to ensure a better seal for your piston rings, which translates directly into more power. The cam and barrel skirt profiles are carefully shaped to help generate power while also being designed to work smoothly with your cylinder walls.

A notable aspect of Manley's manufacturing process is their unique fixturing, which allows them to machine the skirt and ring grooves in the same operation. This ensures the ring grooves are perfectly square to the piston skirt, a detail that matters for optimal engine function. These pistons are a popular choice among professional engine builders and tuners who rely on Manley for their performance and durability.
