Mahle MS Piston Set GM LS 366ci 4.010in Bore 3.622stk 6.125in Rod 0.927 Pin 2cc 10.5 CR Set of 8

If you're building or rebuilding a GM LS engine for serious performance, this Mahle MS Piston Set is a solid choice. Designed for 366 cubic inch applications, these pistons are crafted to handle the demands of a high-performance engine build. They feature a 4.010-inch bore and are designed to work with a 3.622-inch stroke, a 6.125-inch connecting rod, and a 0.927-inch wrist pin. This specific configuration helps achieve a 10.5:1 compression ratio with a 2cc dish volume, which is ideal for many naturally aspirated or forced induction setups looking for improved power without excessive detonation risk.

Mahle uses a 4032 aluminum alloy for these pistons, a material known for its strength and thermal expansion properties, making it well-suited for performance applications where heat and stress are significant factors. Each piston weighs in at 472 grams, contributing to a balanced rotating assembly. The set includes eight pistons, ensuring you have everything needed for a complete engine rebuild. These are a well-built component that forms the heart of your engine's power delivery system.

It's important to note that these pistons are not CARB approved and cannot be shipped to California. Always refer to your engine builder's specifications and the manufacturer's installation instructions for proper fitment and assembly procedures to ensure optimal performance and longevity of your engine build.
