Mahle MS Piston Set GM LSX 364cid 4.000x1.330CH 3.622 Stk 6.098 Rod .945 Pin -5.8cc 9.9CR - Set of 8

If you're building or rebuilding a GM LSX 364 cubic inch engine, this Mahle MS Piston Set is a solid choice for serious performance. These pistons are crafted from 2618 aluminum, a material known for its strength and ability to handle the high temperatures and pressures found in performance applications. The set includes eight pistons, each precisely machined to a 4.000-inch bore size, with a 1.330-inch compression height. This specific compression height works with a 3.622-inch stroke crankshaft and a 6.098-inch connecting rod, maintaining a stock-like deck height for easier assembly.

Mahle has engineered these pistons with a -5.8cc dish volume, which, when combined with the other engine components, results in a 9.9:1 compression ratio. This ratio is a popular target for naturally aspirated or boosted LSX builds, offering a good balance of power and drivability. The included wrist pins are 0.945 inches in diameter, a common size for performance LSX engines. Each piston weighs approximately 440 grams, contributing to a well-balanced rotating assembly. This set is designed for performance builds where reliability and strength are paramount.

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