Manley Chevrolet LS Piston Set - 4.165in Bore 1.315in CH, -11.00 CC

Manley Performance is well-known for building robust engine components, and their Platinum Series pistons are a prime example of that dedication. If you're building a high-performance Chevrolet LS engine, this piston set is designed to handle serious power. These pistons feature a 4.165-inch bore and a -11.00 CC dish, which is a common configuration for naturally aspirated or forced induction builds where specific compression ratios are targeted.

Crafted from domestic 2618 alloy forgings, these pistons offer exceptional strength, making them a solid choice for demanding engine builds. They utilize proven cam and barrel skirt profiles, which help generate power efficiently while also being gentle on your cylinder walls during operation. The ring lands and grooves are machined to exacting standards, ensuring a tight seal for improved combustion and power output. Manley's unique fixturing process allows them to machine the skirt and ring grooves in one operation, which guarantees ultimate squareness between the piston skirt and the ring grooves. This attention to detail contributes to better ring seal and overall engine performance.

This set includes premium Chrome Moly wrist pins, known for their durability. For those pushing the limits, Manley offers upgrades to 9310 and Turbo Tuff/DLC alloys on select part numbers for even greater strength. Keep in mind that these pistons are not CARB approved and cannot be shipped to California. They are intended for off-road or racing applications where emissions compliance is not a requirement.
