About this part

Product Details

This Mahle MS piston set is designed for Chevy Small Block engines, specifically for builds targeting around 393 cubic inches. You get a complete set of pistons, ready to be installed in your performance engine. These pistons are forged from 2618 aluminum, a strong material chosen for its durability under high stress, making them a solid choice for serious engine builds where reliability is key.

With a 4.155-inch bore and a -9cc dish volume, these pistons are engineered to work with a 3.625-inch stroke crankshaft and a 6.125-inch connecting rod, contributing to a 13.1:1 compression ratio. The included .927-inch pins are also well-built for the demands of a performance application. The 414-gram weight per piston is typical for forged units of this size, balancing strength with reasonable reciprocating mass.

Keep in mind that these pistons are not CARB approved and cannot be shipped to California. If you're building a high-performance engine and need pistons that can handle the stress, this Mahle set is a well-regarded option.
