Custom forged pistons for the Mercedes-AMG ML63 (W164) — purpose-built for the M156 6.2L naturally aspirated V8 to handle the extreme cylinder pressures of forced-induction conversions and high-RPM operation.
The M156 is one of the strongest factory AMG engines ever produced, but the factory cast pistons are the first failure point when adding a supercharger, turbocharger, or pushing sustained high-RPM operation. Our forged piston set delivers the strength needed to survive forced-induction builds without the full cost of a complete forged internals kit.
What's Included
- 8x Forged Pistons — 4340 aircraft-quality forged aluminum, precision-machined to OEM bore specifications for the M156 6.2L V8
- Piston Rings — Low-tension performance ring pack for improved sealing and reduced friction
- Wrist Pins & Clips — Heavy-duty tool steel wrist pins rated for extreme cylinder pressures
Key Features
- Ceramic-Coated Tops — Thermal barrier coating reduces heat transfer to the piston crown, protecting against detonation under boost or aggressive timing.
- Teflon-Coated Skirts — Anti-friction coating reduces piston-to-wall contact friction, improving reliability and reducing wear under sustained high-RPM operation
- Factory Compression Ratio — Maintains stock compression geometry for seamless integration with OEM or aftermarket ECU calibrations
- 1,500HP+ Rated — Engineered to withstand cylinder pressures generated by supercharger and turbocharger conversions pushing well beyond factory output.
Compatibility
- Mercedes-AMG ML63 (W164) — 2007–2011
- Engine: M156 6.2L Naturally Aspirated V8
Why YPG Motorsport?
YPG Motorsport has built and tuned M156-powered AMGs since 2011 — from naturally aspirated race builds to full forced-induction conversions. Every kit is sourced from CP-Carrillo or equivalent tier-1 forging houses and inspected before shipping.
