Mahle MS Piston Set GM LSA/LS3/LS9 4.070in Bore 3.622stk 6.125in Rod .927 Pin -4.5cc 10 CR Set of 8

This Mahle MS Piston Set includes eight forged pistons designed for GM LSA, LS3, and LS9 engines. These pistons are built to handle the demands of high-performance applications, featuring a 4.070-inch bore and a 3.622-inch stroke, which combine with a 6.125-inch rod to create a 377 cubic inch displacement. The -4.5cc dish volume contributes to a 10.0:1 compression ratio when paired with compatible cylinder heads, making them suitable for naturally aspirated or boosted setups.

Crafted from 2618 aluminum, these pistons are known for their strength and durability under high temperatures and pressures. Each piston weighs approximately 480 grams, contributing to a balanced rotating assembly. The 0.927-inch pin diameter is standard for many performance LS applications. This set is compatible with all LS cylinder heads, offering flexibility in your engine build.

Please note that this piston set is not CARB approved and cannot be shipped to California. It is important to consult with your engine builder or refer to Mahle's technical documentation for specific installation requirements and compatibility with other engine components to ensure optimal performance and longevity.
