Mahle MS Piston Set GM LSX 443cid 4.135x1.050RCH 4.125 Stk 6.125 Rod .927 Pin -5.8cc 11.7CR Set of 8

When you're building a serious performance engine, especially a GM LSX with a 443 cubic inch displacement, the pistons are a critical component. This set from Mahle gives you eight of their MS series pistons, designed for a 4.135-inch bore and engineered to work with a 4.125-inch stroke crankshaft and a 6.125-inch connecting rod. They feature a 0.927-inch wrist pin and a -5.8cc dish, which helps achieve an 11.7:1 compression ratio with the right cylinder heads.

These pistons are constructed from 2618 aluminum, a well-known material for its strength and durability in high-performance applications. Each piston weighs in at 443 grams, a spec that indicates a balance between strength and rotational mass. The 1.050-inch compression height is also a key measurement, ensuring proper piston-to-valve clearance and deck height in your build. Mahle is a well-known name in engine components, and this set reflects their focus on providing reliable parts for demanding engine builds.

It's important to note that this piston set is not CARB approved and cannot be shipped to California. Always refer to your engine build specifications and manufacturer's instructions for proper installation and compatibility with other components like rings, bearings, and cylinder heads.
