The original spring-loaded mechanical tensioner experiences spring rate fatigue over time, reducing contact pressure across the pulley track. Simultaneously, factory pulley bearings lose their internal lubricant, causing high-friction wear, race chatter, and pulley misalignment. This results in belt glazing, audible chirping, erratic alternator output, and potential belt throw that disables the water pump and power steering.\u003c\/p\u003e\n\n\u003ch3\u003eThe Engineering Solution\u003c\/h3\u003e\n\u003cp\u003eThis comprehensive service kit restores mechanical stability using upgraded materials engineered for high torsional stress. The assembly features heavy-duty cast construction with a calibrated internal damping spring that absorbs harmonic spikes and prevents belt flutter. Both the tensioner pulley and the \u003cstrong\u003e38018\u003c\/strong\u003e idler pulley utilize precision sealed radial ball bearings packed with high-temperature synthetic grease to prevent bearing seizure. Paired with a heavy-duty EPDM multi-rib belt (\u003cstrong\u003e6PK2020\u003c\/strong\u003e), this kit provides maximum resistance to thermal cracking, rib degradation, and elongation under sustained commercial towing loads.\u003c\/p\u003e\n\n\u003ch3\u003eWhat's Included\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003e1x Serpentine Belt (Part # 6PK2020)\u003c\/li\u003e\n  \u003cli\u003e1x Idler Pulley (Part # 38018)\u003c\/li\u003e\n  \u003cli\u003e1x Belt Tensioner Assembly (Part # 38323)\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;\"\u003e2011-2018 Ram 3500\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;\"\u003e5.7L HEMI V8 \/ D2\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;\"\u003e383 hp \/ 400 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;\"\u003e6PK2020, 38018, 38323\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\u003e2011-2018 Ram 3500 (5.7L V8 HEMI)\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 D2 3500?\u003c\/h4\u003e\n\u003cp\u003eYes, this is a direct fit for the 2011-2018 Ram 3500 equipped with the \u003cstrong\u003e5.7L HEMI V8\u003c\/strong\u003e engine. \u003cstrong\u003eThis kit does not fit 6.4L HEMI V8 gas or 6.7L Cummins Turbo Diesel configurations.\u003c\/strong\u003e\u003c\/p\u003e\n\n\u003ch4\u003eShould the belt, tensioner, and idler pulley be replaced simultaneously?\u003c\/h4\u003e\n\u003cp\u003eYes, replacing all components concurrently ensures matched rotational wear, correct dynamic tension, and prevents premature failure of a new belt on worn pulley bearings.\u003c\/p\u003e\n\n\u003ch3\u003eThe Ram Heavy Duty Caliber\u003c\/h3\u003e\n\u003cp\u003eCommercial-grade towing and extreme payload demands require an uncompromising front accessory drive; this performance kit ensures reliable charging and cooling performance under the most demanding operating conditions.\u003c\/p\u003e","brand":"VelocityMax","offers":[{"title":"Default Title","offer_id":67547051950328,"sku":"DS-ESMW4YNBK","price":71.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0800\/1290\/2648\/files\/performance-drive-belt-tensioner-kit-for-ram-3500-2011-2018-5-7l-1.jpg?v=1790740009","url":"https:\/\/performancechiptuning.com\/fr\/products\/performance-drive-belt-tensioner-kit-for-ram-3500-2011-2018-5-7l","provider":"Performance Chip Tuning","version":"1.0","type":"link"}
