Manley Small Block Chevrolet LS Series -29cc Dish 4.075 Bore 4in Stroke Top Piston Set - E/D

When you're building a high-performance Small Block Chevrolet LS engine, you need pistons that can handle the stress. This set from Manley Performance includes eight forged pistons, each featuring a -29cc dish, a 4.075-inch bore, and designed for a 4-inch stroke. These are the same pistons trusted by professional engine builders for their proven performance and durability.

Manley uses domestic 2618 alloy forgings for these pistons, which are known for their exceptional strength. They also come standard with chrome moly wrist pins, offering solid durability for most builds. For those pushing the limits, Manley offers upgrades to 9310 and Turbo Tuff/DLC alloys. The pistons feature carefully machined ring lands and grooves to ensure a tight seal, which translates directly to more power. Their unique cam and barrel skirt profiles are designed to generate power efficiently while minimizing wear on your cylinder walls. Manley's specialized machining process ensures the ring grooves are perfectly square to the piston skirts, a detail that makes a difference in engine longevity and performance.

This set is designed for serious engine builds and is not CARB approved, meaning it cannot be shipped to California. Ensure you check all manufacturer specifications and local regulations before installation.
