Mercedes-AMG M156 Forged Internals — Rods & Pistons Kit

The Mercedes-AMG M156 6.2L naturally aspirated V8 is one of the strongest factory AMG engines ever built — the stock bottom end handles 750–800HP before internals become the limiting factor. However, when you are building beyond that for supercharger or turbo conversions, forged rods and pistons are non-negotiable. Our M156 forged internals kit replaces the stock cast components with race-grade 4340 steel rods and forged pistons rated for 1,500HP and beyond.

What's Included:
Forged 4340 aircraft-grade steel connecting rods — H-beam design
Forged pistons — CP or equivalent, matched to M156 102.2mm bore
ARP rod bolts — 220,000 PSI rated
Wrist pins and ring set included
Balanced and matched set — within ±1.5g

Compatible Vehicles:
C63 AMG W204 (2008–2015) — all variants including 507 Edition
E63 AMG W211 (2006–2009) and W212 (2009–2011)
CLS63 AMG W219 (2006–2011)
SL63 AMG R230 (2008–2011)
ML63 AMG W164 (2007–2011)
GL63 AMG X164 (2008–2011)
S63 AMG W221 (2006–2010)
CLK63 AMG W209
CL63 AMG W216 (2007–2010)

Why Upgrade?
The stock M156 bottom end uses cast hypereutectic pistons (forged on 2010+ P31 package cars) and strong connecting rods. While excellent for street use, sustained high-boost operation on supercharger or turbo builds generates heat cycles that fatigue cast components over time. Forged internals absorb shock loads, handle extreme cylinder pressures, and run cooler under sustained wide-open throttle. For any M156 build targeting 800HP+, forged internals are the foundation everything else is built on.
