Manley Chevrolet LS Piston Set - 4.130in Bore 1.065in CH, -20.00 CC

If you're building a high-performance Chevrolet LS engine, this Manley Performance Piston Set is a solid choice. Designed for a 4.130-inch bore, these pistons feature a -20.00cc dish and a 1.065-inch compression height, making them suitable for many performance applications where specific compression ratios are targeted. Manley is a well-known name among professional engine builders for a reason; their pistons are built to handle serious power.

These pistons are forged from 2618 alloy, a material chosen for its exceptional strength and ability to withstand the high pressures and temperatures found in performance engines. They feature proven cam and barrel skirt profiles, which help reduce friction and wear on your cylinder walls while still generating substantial power. The ring lands and grooves are machined to exacting standards, ensuring a tight seal for improved combustion efficiency and more power output. For added durability, these pistons come standard with chrome moly wrist pins, and Manley's unique fixturing process ensures the ring grooves are perfectly square to the skirt, which is critical for proper ring seal.

This set includes eight pistons, eight chrome moly wrist pins, and eight sets of spiral locks. Please note that these pistons are not CARB approved and cannot be shipped to California. It's always a good idea to consult with your engine builder or refer to Manley's technical documentation to confirm compatibility with your specific build and ensure proper installation for optimal performance and longevity.
