Mahle MS Piston Set GM LS 4.075in Bore 3.622in Stk 6.125in Rod .927 Pin 12cc 12.3 CR Set of 8 - TBC

This Mahle MS Piston Set includes eight forged pistons designed for GM LS engines with a 378 cubic inch displacement. Each piston features a 4.075-inch bore, a 3.622-inch stroke, and is designed to work with a 6.125-inch connecting rod and a 0.927-inch wrist pin. These pistons are constructed from 2618 aluminum, a material known for its strength and durability under high stress, making them a solid choice for performance builds. The pistons weigh 494 grams each and have a 12cc dish volume, contributing to a 12.3:1 compression ratio when paired with the correct cylinder heads and gasket combination.

The TBC coating on these pistons is a thermal barrier coating that helps reduce heat transfer into the piston crown, which can lead to improved performance and longevity, especially in high-output applications. This coating also offers some wear resistance. The 2618 aluminum alloy provides excellent strength for demanding engine builds, and the included wrist pins are designed for a precise fit. This set is intended for builders looking to assemble a robust and powerful LS engine, whether for track use, street performance, or other high-demand scenarios.

When installing this piston set, ensure you are using appropriate assembly lubricants and following manufacturer guidelines for ring gap and bearing clearances. It's important to note that these pistons are not CARB approved and cannot be shipped to California. Always consult your engine builder or a trusted mechanic to confirm compatibility with your specific cylinder heads, crankshaft, and connecting rods to achieve your desired engine specifications.
