Mercedes-AMG M177 Forged Internals — Rods & Pistons Kit ★ World Record Spec
The Mercedes-AMG M177 4.0L twin-turbo V8 is the heart of the W205 C63, W213 E63, and AMG GT family. It is also the engine that — in the hands of our team — became the first W205 C63 in history to run a 9-second quarter mile (9.97s at 828 WHP at Kuwait Motor Town). Our M177 forged internals kit is the exact specification used in that world record build.
The stock M177 rods become the limiting factor above 700HP under sustained high-boost operation — ours don't.
