Mahle MS Piston Set Chevrolet LS 4.005 Bore 1.110 CH 4.000 Stk 6.125 Rod 0.927 Pin -5.8cc - Set of 8

If you're building or rebuilding a Chevrolet LS engine and need a solid set of pistons, this Mahle MS Piston Set is a well-built option. These pistons are designed for a 4.005-inch bore and are part of a set that will bring your 403 cubic inch LS engine to life. They feature a 4.000-inch stroke compatibility, a 6.125-inch rod length, and a 0.927-inch pin diameter, all common specifications for many LS engine builds.

Mahle has engineered these pistons with a -5.8cc dish volume, which helps achieve a specific compression ratio, calculated here at 11.4:1 with the listed components. They are constructed from 4032 aluminum, a material known for its good thermal expansion properties, making it suitable for performance applications where temperatures can rise. Each piston weighs in at 404 grams, contributing to a balanced rotating assembly. This set includes all eight pistons needed for a V8 engine.

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