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.\u003c\/p\u003e\n\u003cp\u003eWhat's Included:\u003cbr\u003eForged 4340 aircraft-grade steel connecting rods — H-beam design\u003cbr\u003eForged pistons — CP or equivalent, matched to M156 102.2mm bore\u003cbr\u003eARP rod bolts — 220,000 PSI rated\u003cbr\u003eWrist pins and ring set included\u003cbr\u003eBalanced and matched set — within ±1.5g\u003c\/p\u003e\n\u003cp\u003eCompatible Vehicles:\u003cbr\u003eC63 AMG W204 (2008–2015) — all variants including 507 Edition\u003cbr\u003eE63 AMG W211 (2006–2009) and W212 (2009–2011)\u003cbr\u003eCLS63 AMG W219 (2006–2011)\u003cbr\u003eSL63 AMG R230 (2008–2011)\u003cbr\u003eML63 AMG W164 (2007–2011)\u003cbr\u003eGL63 AMG X164 (2008–2011)\u003cbr\u003eS63 AMG W221 (2006–2010)\u003cbr\u003eCLK63 AMG W209\u003cbr\u003eCL63 AMG W216 (2007–2010)\u003c\/p\u003e\n\u003cp\u003eWhy Upgrade?\u003cbr\u003eThe 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.\u003cbr\u003e\u003c\/p\u003e\u003ch3\u003eRelated Products\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e\u003ca href=\"\/products\/m156-crankshaft-damper-pulley\"\u003eM156 Crankshaft Damper Pulley — $1399.00\u003c\/a\u003e\u003c\/li\u003e\n\u003cli\u003e\u003ca href=\"\/products\/m156-crate-engine\"\u003eM156 Crate Engine | 1,500HP+ Build — $25999.00\u003c\/a\u003e\u003c\/li\u003e\n\u003cli\u003e\u003ca href=\"\/products\/mercedes-benz-w205-c63-c63s-2015\"\u003eMercedes-Benz M156 High Flow Air Filters — $199.00\u003c\/a\u003e\u003c\/li\u003e\n\u003cli\u003e\u003ca href=\"\/products\/race-long-tube-headers\"\u003eM156 Race Long Tube Headers — $1999.99\u003c\/a\u003e\u003c\/li\u003e\n\u003c\/ul\u003e\u003cscript type=\"application\/ld+json\"\u003e{\"@context\":\"https:\/\/schema.org\",\"@type\":\"BreadcrumbList\",\"itemListElement\":[{\"@type\":\"ListItem\",\"position\":1,\"name\":\"Shop\",\"item\":\"https:\/\/ypgmotorsport.com\/collections\/all\"},{\"@type\":\"ListItem\",\"position\":2,\"name\":\"Mercedes-Benz AMG M156 Forged Internals| Rods \u0026 Pistons\",\"item\":\"https:\/\/ypgmotorsport.com\/products\/mercedes-benz-amg-156-forged-internals\"}]}\u003c\/script\u003e\n\u003cdiv class=\"product-faq\" style=\"margin-top:24px;border-top:1px solid #e0e0e0;padding-top:20px;\"\u003e\n\u003ch3 style=\"font-size:18px;font-weight:bold;margin-bottom:16px;\"\u003eFrequently Asked Questions\u003c\/h3\u003e\n\u003cdetails style=\"margin-bottom:12px;\"\u003e\u003csummary style=\"font-weight:600;cursor:pointer;padding:8px 0;\"\u003eHow much does the Mercedes-Benz AMG M156 Forged Internals| Rods \u0026amp; Pi cost?\u003c\/summary\u003e\u003cp style=\"padding:8px 0 8px 16px;color:#555;\"\u003eThe Mercedes-Benz AMG M156 Forged Internals| Rods \u0026amp; Pi is $5999.00 through YPG Motorsport with free worldwide shipping.\u003c\/p\u003e\u003c\/details\u003e\u003cdetails style=\"margin-bottom:12px;\"\u003e\u003csummary style=\"font-weight:600;cursor:pointer;padding:8px 0;\"\u003eAre these drop-in replacements?\u003c\/summary\u003e\u003cp style=\"padding:8px 0 8px 16px;color:#555;\"\u003eYes.
