Manley Chevrolet LS Piston Set - 4.065in Bore 1.065in CH, -31.00 CC

Manley's 596765CE-8 piston set starts with domestic 2618 alloy forgings, a material chosen for its exceptional strength and ability to handle high performance demands. These pistons are specifically designed for Chevrolet LS engines, featuring a 4.065-inch bore and a -31.00 CC dish, which is a key factor in determining your engine's compression ratio. The 1.065-inch compression height is also critical for proper piston-to-valve clearance and deck height, ensuring your engine components work together harmoniously.

You'll find these pistons come equipped with premium chrome moly wrist pins, known for their durability. Manley also applies their signature cam and barrel skirt profiles, which are engineered to generate significant power while minimizing wear on your cylinder walls. They maintain exacting standards for ring lands and grooves, which is essential for achieving a solid ring seal and maximizing the power your engine can produce. The unique fixturing Manley uses allows them to machine the skirt and ring grooves in one operation, ensuring a precise squareness that contributes to overall engine health and performance.

This set is a popular choice among professional engine builders and tuners who need reliable components for high-output builds. It's important to note 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.
