Mahle MS Piston Set GM LSX 429cid 4.070x1.050RCH 4.125 Stk 6.125 Rod .927 Pin -5.8cc 11.4CR Set of 8

Mahle is well-known for making solid engine components, and this MS Piston Set is a prime example of their work for GM LSX engines. If you're building a high-performance 429 cubic inch LSX, these pistons are designed to handle the demands of a serious build. They're crafted from 2618 aluminum, a material chosen for its strength and ability to withstand high temperatures and pressures common in performance applications.

This set is specifically engineered for a 4.070-inch bore and a 4.125-inch stroke, working with a 6.125-inch rod and a 0.927-inch pin. The dish volume is -5.8cc, which, combined with the other specifications, results in an 11.4:1 compression ratio. This compression level is ideal for naturally aspirated or forced induction setups where you want improved power output without going overboard. Each piston weighs in at 429 grams, contributing to a well-balanced rotating assembly.

This is a set of 8 pistons, providing everything you need for a complete engine rebuild. Please note that these pistons are not CARB approved and cannot be shipped to California. They also come with a Prop 65 warning.
