Mahle MS Piston Set GM LT1 377ci 4.07in Bore 3.622in Stk 6.125in Rod -16cc 11.6 CR Set of 8

Mahle's MS Piston Set is built for GM LT1 engines, specifically for builds targeting 377 cubic inches with a 4.070-inch bore. These pistons are designed with an inverted dome to work with GM LT1, L86, and LT4 cylinder heads, aiming for an 11.6:1 compression ratio. This setup is a solid choice for enthusiasts looking to extract more power from their LT-series engine.

Each piston in this set is crafted from 2618 aluminum, a material known for its strength and ability to handle high temperatures and pressures, making it ideal for performance applications. They feature a 3.622-inch stroke compatibility and are designed to pair with a 6.125-inch connecting rod, with a 0.927-inch wrist pin. The pistons weigh in at 442 grams each, contributing to a well-balanced rotating assembly. The -16cc dish volume is key to achieving that 11.6:1 compression ratio when paired with compatible heads.

This set includes eight pistons, enough to rebuild a full V8 engine. It's important to note that these pistons are not CARB approved and cannot be shipped to California. For optimal results and longevity, ensure these are installed by a qualified professional who can adhere to precise clearances and assembly procedures.
