Mahle MS Piston Set GM LT 6.2L 428ci 4.125in B 4.000in S 6.125in R .927 P -6.1cc 12.7 CR Set of 8

This is a set of eight Mahle forged pistons designed for GM LT 6.2L (428 cubic inch) engines. These pistons feature a flat top design and are compatible with GM LT1, L86, and LT4 cylinder heads. They are constructed from 2618 aluminum, a strong material commonly used for high-performance pistons, and come with a skirt coating (TBC) to help reduce friction and noise during operation.

Each piston in this set measures 4.125 inches in bore diameter and is designed to work with a 4.000-inch stroke crankshaft and a 6.125-inch connecting rod. The wrist pin diameter is 0.927 inches. The piston dish volume is -6.1cc, which, when combined with the other engine components, results in a compression ratio of 12.7:1. This specific configuration is often chosen for builds looking for improved performance over stock, especially when paired with aftermarket cylinder heads and camshafts.

Included in this set are the eight pistons, ready for installation. Please note that these pistons are not CARB approved and cannot be shipped to California. It's always a good idea to consult your engine builder or a trusted mechanic to ensure these pistons are the right fit for your specific build goals and to review the complete installation instructions provided by Mahle.
