Manley Chevrolet LS Piston Set - 4.070in Bore 1.065in CH, -31.00 CC

If you're building a high-performance Chevrolet LS engine, this Manley Piston Set is a solid choice for serious power. These pistons are designed for a 4.070-inch bore and feature a -31.00 CC dish, which is crucial for setting your compression ratio. Manley is a well-known name among professional engine builders, and this set is part of their Platinum Series, meaning they're built to handle demanding conditions.

What sets these pistons apart is the material: they're forged from domestic 2618 alloy. This material is chosen for its exceptional strength and durability, which is essential when you're pushing an engine hard. They also come with tool steel wrist pins and feature moly skirt coatings on select part numbers, further enhancing their longevity and reducing friction against the cylinder walls. Manley pays close attention to the details, like the exacting standards for ring lands and grooves, which directly impacts how well your piston rings seal. This improved seal means more consistent power output and better control over combustion. The cam and barrel skirt profiles are also carefully engineered to generate power efficiently while minimizing wear on your cylinder walls.

When you're assembling an engine, precision is key. Manley uses a unique fixturing process that allows them to machine the skirt and ring grooves in a single operation. This ensures the ring grooves are perfectly square to the piston skirt, which is vital for optimal ring seal and overall engine health. This set includes eight pistons, eight wrist pins, and eight sets of locks. Keep in mind that these pistons are not CARB approved and cannot be shipped to California. Always refer to the manufacturer's installation instructions for proper fitment and assembly procedures.
