Manley Chevrolet LS Piston Set - 4.165in Bore 1.115in CH, -11.00 CC

Manley Performance is well-known for building robust engine components, and their LS piston sets are a popular choice among serious engine builders. This particular set is designed for Chevrolet LS engines, featuring a 4.165-inch bore and a -11.00cc dish volume, making it suitable for specific performance builds where precise compression ratios are key. The 1.115-inch compression height is also a critical dimension for achieving the desired piston-to-valve clearance and deck height in your engine.

These pistons are forged from domestic 2618 alloy, a material chosen for its exceptional strength and ability to handle high performance demands without failing. They also come standard with premium chrome moly wrist pins, which are strong and durable for everyday use. Manley pays close attention to the details, ensuring exacting standards for the ring lands and grooves. This precision leads to a better seal with your piston rings, which directly translates to more power and better engine efficiency. The cam and barrel skirt profiles are also carefully designed to generate power while minimizing wear on your cylinder walls, a testament to Manley's experience in engine building.

What sets Manley apart is their unique fixturing process. It allows them to machine the skirt and the ring grooves in a single operation. This ensures that the ring grooves are perfectly square to the piston skirt, which is crucial for optimal ring seal and overall engine health. This set includes the pistons and wrist pins; rings are sold separately, so be sure to select a set that matches your bore size and application needs.
