Mahle MS Piston Set GM LSX 404cid 4.010x1.110RCH 4.000 Stk 6.125 Rod .927 Pin -5.8cc 10.8CR Set of 8

This Mahle MS Piston Set gives you everything you need to rebuild the heart of your GM LSX 404 cubic inch engine. You get a full set of eight forged pistons, along with the necessary wrist pins and locks, all designed to work together for a solid foundation. These pistons are built for a 4.010 inch bore and are designed to pair with a 4.000 inch stroke crankshaft and a 6.125 inch connecting rod, featuring a 0.927 inch pin diameter.

Mahle uses 2618 aluminum for these pistons, a strong material commonly chosen for high-performance applications where durability under stress is key. Each piston weighs in at 416 grams and features a -5.8cc dish volume, which helps achieve a 10.8:1 compression ratio when used with the specified components. This setup is ideal for builders looking to enhance their LSX engine's power and efficiency. Remember, these pistons are not CARB approved and cannot be shipped to California.

When undertaking a rebuild of this caliber, ensuring all components are properly matched is crucial. This set provides a well-matched piston, pin, and lock combination, simplifying the assembly process. Always refer to your engine build specifications and manufacturer instructions for proper installation and torque procedures.
