Mahle MS Piston Set SBM 408ci 4.03in Bore 4.00in Stroke 6.123in Rod .984 Pin -16cc 10.3 CR Set of 8

If you're building a high-performance 408 cubic inch Small Block Mopar engine, a solid set of pistons is where you start. This Mahle MS Piston Set is designed for those looking to get the most out of their LA-series 340 or 360 block, pushing it out to 408ci. These pistons are forged from 4032 aluminum, a material known for its strength and durability under high stress, making them a well-built choice for serious engine builds.

This set features a 4.030 inch bore and is designed to work with a 4.000 inch stroke crankshaft and a 6.123 inch connecting rod, giving you a specific compression ratio of 10.4:1 with a -16cc dish volume. The .984 inch pin diameter is standard for many performance applications. Each piston weighs in at approximately 480 grams, contributing to a balanced rotating assembly. Mahle is a well-known name in engine components, and this piston set reflects their commitment to providing reliable parts for performance engine work.

Keep in mind that these pistons are not CARB approved and cannot be shipped to California. For a complete engine build, ensure you have all the necessary supporting components, such as rings, bearings, and a balanced crankshaft, to match these high-performance pistons.
