The OEM stamped-steel or composite pulley features a wide outer lip that makes physical contact with upgraded harmonic balancers and supercharger drive belts. Furthermore, standard aftermarket underdrive pulleys compromise low-speed coolant velocity, driving up engine coolant temperatures and exacerbating supercharger heat soak during aggressive driving or dyno pulls.\u003c\/p\u003e\n\n\u003ch3\u003eThe Engineering Solution\u003c\/h3\u003e\n\u003cp\u003ePrecision CNC-machined in the USA from aerospace-grade 6061-T6 billet aluminum, this replacement pulley features a specialized stepped snout and reduced outer flange profile. This geometry provides essential radial clearance for large-diameter crank pulleys while preserving the exact OEM running diameter and rotational speed of the factory cooling system. Finished in a mil-spec hard-anodized protective coating, it resists belt abrasion, thermal fatigue, and chemical degradation while reducing rotational mass on the accessory drive.\u003c\/p\u003e\n\n\u003ch3\u003eWhat's Included\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003e1 x billet water pump pulley\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eTechnical Specifications\u003c\/h3\u003e\n\u003cdiv style=\"overflow-x: auto; margin-bottom: 20px;\"\u003e\n  \u003ctable width=\"100%\" style=\"border-collapse: collapse; border: 1px solid #e0e0e0; font-size: 14px; min-width: 300px;\"\u003e\n    \u003ctr style=\"background-color: #f9f9f9;\"\u003e\n\u003cth style=\"padding:10px; text-align: left; border: 1px solid #e0e0e0;\"\u003eFitment\u003c\/th\u003e\n\u003ctd style=\"padding:10px; border: 1px solid #e0e0e0;\"\u003e2003-2011 Mercedes Benz E-Class, CLS-Class, CL-Class, S-Class, SL-Class, G-Class AMG\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003cth style=\"padding:10px; text-align: left; border: 1px solid #e0e0e0;\"\u003eEngine \/ Chassis\u003c\/th\u003e\n\u003ctd style=\"padding:10px; border: 1px solid #e0e0e0;\"\u003e\n\u003cstrong\u003eM113.990 \/ M113K\u003c\/strong\u003e \/ \u003cstrong\u003eW211, C219, C215, W220, R230, W463\u003c\/strong\u003e\n\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr style=\"background-color: #f9f9f9;\"\u003e\n\u003cth style=\"padding:10px; text-align: left; border: 1px solid #e0e0e0;\"\u003eStock Output\u003c\/th\u003e\n\u003ctd style=\"padding:10px; border: 1px solid #e0e0e0;\"\u003e469-510 hp \/ 516-531 lb-ft\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003cth style=\"padding:10px; text-align: left; border: 1px solid #e0e0e0;\"\u003eReplaces OEM Part #\u003c\/th\u003e\n\u003ctd style=\"padding:10px; border: 1px solid #e0e0e0;\"\u003eN\/A\u003c\/td\u003e\n\u003c\/tr\u003e\n  \u003c\/table\u003e\n\u003c\/div\u003e\n\n\u003ch3\u003eCompatibility\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003e2003-2008 Mercedes Benz E-Class E55 AMG 5.5L\u003c\/li\u003e\n  \u003cli\u003e2003-2008 Mercedes Benz CLS-Class CLS55 AMG 5.5L\u003c\/li\u003e\n  \u003cli\u003e2003-2008 Mercedes Benz CL-Class CL55 AMG 5.5L\u003c\/li\u003e\n  \u003cli\u003e2003-2008 Mercedes Benz S-Class S55 AMG 5.5L\u003c\/li\u003e\n  \u003cli\u003e2003-2008 Mercedes Benz SL-Class SL55 AMG 5.5L\u003c\/li\u003e\n  \u003cli\u003e2005-2011 Mercedes Benz G-Class G55 AMG 5.5L\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eFrequently Asked Questions \u0026amp; Fitment Warnings\u003c\/h3\u003e\n\u003ch4\u003eDoes this fit the W211, C219, C215, W220, R230, and W463 E-Class, CLS-Class, CL-Class, S-Class, SL-Class, and G-Class?\u003c\/h4\u003e\n\u003cp\u003eYes, this is a direct fit for the 2003-2011 Mercedes Benz AMG models equipped with the supercharged \u003cstrong\u003eM113K\u003c\/strong\u003e 5.5L V8 engine. \u003cstrong\u003eThis component does not fit naturally aspirated 5.5L M113 engines or later M156 6.2L V8 platforms.\u003c\/strong\u003e\u003c\/p\u003e\n\n\u003ch4\u003eWill this pulley alter factory coolant circulation rates or require ECU tuning?\u003c\/h4\u003e\n\u003cp\u003eNo, the effective drive diameter retains standard OE water pump speed to prevent high-rpm cavitation or low-rpm cooling loss, and direct replacement requires no engine calibration.\u003c\/p\u003e\n\n\u003ch3\u003eThe Mercedes Benz Precision Standard\u003c\/h3\u003e\n\u003cp\u003eEngineered for high-output European supercharged powertrains, this CNC billet component maintains factory thermal management while providing zero check engine lights and reliable clearances under heavy boost conditions.\u003c\/p\u003e","brand":"VelocityMax","offers":[{"title":"Default Title","offer_id":67558854885624,"sku":"DS-EWO8RWUD2","price":168.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0800\/1290\/2648\/files\/upgraded-water-pump-pulley-for-mercedes-benz-e-class-cls-class-cl-class-s-class-sl-class-g-class-e55-cls55-cl55-s55-sl55-g55-2003-2011-5-5l-1.jpg?v=1790925436","url":"https:\/\/performancechiptuning.com\/fr\/products\/upgraded-water-pump-pulley-for-mercedes-benz-e-class-cls-class-cl-class-s-class-sl-class-g-class-e55-cls55-cl55-s55-sl55-g55-2003-2011-5-5l","provider":"Performance Chip Tuning","version":"1.0","type":"link"}
