Mahle MS Chevrolet LS 6.8L 417cid 4.070in Bore x 1.110RCH 4.000 Stroke 9.2cc 14.1 CR - Pist Set of 8

This Mahle MS piston set gives you a complete set of eight pistons, ready to be installed in your Chevrolet LS engine. These are forged pistons designed for a 4.070-inch bore and a 4.000-inch stroke, with a 1.110RCH (rod center height) and a 0.927-inch pin. They feature a 9.2cc dish volume, resulting in a 14.1 compression ratio for your 416 cubic inch (6.8L) engine build. Each piston weighs in at 480 grams.

Mahle uses 2618 aluminum for these pistons, a well-known material for high-performance applications due to its strength and durability under extreme conditions. The forged construction means they can handle the higher cylinder pressures and temperatures associated with performance builds, making them a solid choice for serious engine work. The specific dish volume and pin height are carefully calculated to achieve the 14.1 compression ratio when paired with a 6.125-inch rod and the specified bore and stroke.

When rebuilding or upgrading your LS engine, especially for applications that demand more power and reliability, a well-built piston set like this Mahle MS series is crucial. Remember 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.
