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 (formerly Yabeela Parts, now YPG Motorsport) — became the first W205 C63 in history to run a 9-second quarter mile. 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.

What's Included:
Forged 4340 steel connecting rods — rated 1,500HP
Forged CP or Carrillo pistons — 83mm bore compatible
ARP rod bolts — 220,000 PSI rated
Polished crankshaft
Compatible with YPG Stage 4 turbo kit and all methanol/E85 builds
Balanced and matched set — within ±1.5g

Compatible Vehicles:
C63 AMG W205 (2015–2021) — Coupe, Sedan, Cabriolet, Estate
C63 S AMG W205 (2015–2021) — all body styles
E63 AMG W213 (2016–2023) and E63 S AMG W213 (2016–2023)
GLC63 AMG X253 (2017–2022) and GLC63 S AMG
GLE63 AMG V167 (2019–2023) and GLE63 S
GLS63 AMG X167 (2019–2023)

World Record Proven:
The YPG Motorsport / Yabeela Parts Stage 4 build that set the world record for the quickest W205 C63 AMG used this exact forged internals specification combined with our Stage 4 turbo kit and ECU calibration. The car was running these forged internals when it became the first M177-powered C63 to run a 9-second quarter mile. When you order our M177 forged internals, you are ordering the kit that has already proven itself at the highest level.
