Mahle MS Chevrolet LS 6.8L 417cid 4.075in Bore x 1.110RCH 4.000 Stroke 9.2cc 14.1 CR - Pist Set of 8

When you're building a serious performance engine, especially a Chevrolet LS stroker like the 417 cubic inch displacement, the pistons are a critical component. This set from Mahle Motorsport gives you eight forged pistons designed for high-output applications. They feature a 4.075-inch bore and a 4.000-inch stroke, working with a 6.125-inch rod and a 0.927-inch pin. The dish volume is 9.2cc, which, combined with other factors, results in a 14.1:1 compression ratio when used with appropriate cylinder heads and gaskets.

These pistons are forged from 2618 aluminum, a strong and well-built material commonly used in performance racing applications because of its durability and ability to withstand high temperatures and pressures. Each piston weighs in at 482 grams, which is a notable figure for a forged piston of this size. The 1.110RCH (Rod Center Height) specification is important for ensuring proper piston-to-rod geometry and clearance within the engine.

This set is intended for custom engine builds where precise control over compression ratio and performance is key. It's important to note that these pistons are not CARB approved and cannot be shipped to California. Always refer to the manufacturer's detailed installation instructions and consult with your engine builder to ensure proper fitment and assembly for your specific application.
