Mahle MS Piston Set GM LSX 377cid 4.070x1.304CH 3.622 Stk 6.125 Rod .927 Pin -5.8cc 10.2CR Set of 8

If you're building a high-performance GM LSX engine with a 377 cubic inch displacement, this Mahle MS Piston Set is a solid choice. These pistons are specifically designed for applications using a 4.070-inch bore and a 3.622-inch stroke, working with a 6.125-inch connecting rod and a 0.927-inch wrist pin. Mahle is a well-known name in engine components, and this set is built for demanding builds where reliability and performance are key.

Constructed from 2618 aluminum, these pistons are well-built to handle the stresses of a performance engine. They feature a -5.8cc dish volume, which, when combined with the other engine dimensions, results in a 10.2:1 compression ratio. This compression ratio is a popular target for many naturally aspirated and forced induction builds, offering a good balance of power and drivability. Each piston weighs in at 468 grams, which is a reasonable weight for a forged piston of this caliber, contributing to good engine balance.

This set includes all eight pistons needed for a complete engine rebuild. Please note that these pistons are not CARB approved and cannot be shipped to California. Always refer to the manufacturer's installation instructions for proper fitment and assembly procedures.
