The OEM internal spring mechanism in the stock tensioner loses dynamic damping force over time, leading to excessive lateral belt deflection, uneven rib wear, and compromised alternator output under high electrical demands. Furthermore, worn factory idler pulley bearings develop rotational runout, producing audible high-pitched squeal, premature belt shedding, and potential accessory drive failure on the job site.\u003c\/p\u003e\n\n\u003ch3\u003eThe Engineering Solution\u003c\/h3\u003e\n\u003cp\u003eThis comprehensive drive service kit incorporates a reinforced cast aluminum tensioner assembly (\u003cstrong\u003e38158\u003c\/strong\u003e) fitted with an internal heavy-duty coil spring engineered to dampen harmonic vibrations and maintain exact belt tension across the entire RPM range. Paired with a heavy-duty idler pulley (\u003cstrong\u003e38001\u003c\/strong\u003e) housing sealed high-grade steel ball bearings, this system eliminates pulley wobble and grease washout. The included heat- and crack-resistant EPDM serpentine belt (\u003cstrong\u003e6PK2360\u003c\/strong\u003e) maximizes grip on accessory drive pulleys, ensuring reliable 130-amp alternator charging and water pump operation in high-heat conditions.\u003c\/p\u003e\n\n\u003ch3\u003eWhat's Included\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003e1 Serpentine Belt (Part # \u003cstrong\u003e6PK2360\u003c\/strong\u003e)\u003c\/li\u003e\n  \u003cli\u003e1 Idler Pulley (Part # \u003cstrong\u003e38001\u003c\/strong\u003e)\u003c\/li\u003e\n  \u003cli\u003e1 Tensioner Assembly (Part # \u003cstrong\u003e38158\u003c\/strong\u003e)\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;\"\u003e2001-2002 Chevrolet Silverado 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;\"\u003e6.0L Vortec \u003cstrong\u003eLQ4\u003c\/strong\u003e V8 \/ \u003cstrong\u003eGMT800\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;\"\u003e300 hp \/ 360 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;\"\u003e6PK2360, 38001, 38158\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\u003e2001 Chevrolet Silverado 3500 Base \/ LS \/ LT (6.0L V8 Vortec LQ4, 130A Alternator)\u003c\/li\u003e\n  \u003cli\u003e2002 Chevrolet Silverado 3500 Base \/ LS \/ LT (6.0L V8 Vortec LQ4, 130A Alternator)\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 GMT800 Silverado 3500?\u003c\/h4\u003e\n\u003cp\u003eYes, this is a direct fit for the 2001-2002 Chevrolet Silverado 3500 equipped with the 6.0L \u003cstrong\u003eLQ4\u003c\/strong\u003e engine and factory 130 Amp alternator option. \u003cstrong\u003eThis kit does not fit models with the 105 Amp alternator or vehicles equipped with the 6.6L Duramax Diesel or 8.1L Vortec engines.\u003c\/strong\u003e\u003c\/p\u003e\n\n\u003ch4\u003eHow do I verify if my truck has the 130 Amp alternator?\u003c\/h4\u003e\n\u003cp\u003eInspect the service parts identification (SPID) sticker in your glove box for RPO code KG3 to verify 130-amp alternator sizing prior to installation.\u003c\/p\u003e\n\n\u003ch3\u003eThe Chevrolet Heavy-Duty Caliber\u003c\/h3\u003e\n\u003cp\u003eEngineered to handle severe-duty commercial hauling, this tensioner and belt setup provides the mechanical reliability and continuous clamping load necessary to prevent breakdowns under heavy gross combined weight ratings.\u003c\/p\u003e","brand":"VelocityMax","offers":[{"title":"Default Title","offer_id":67546951745784,"sku":"DS-EGHZ9W3SO","price":69.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0800\/1290\/2648\/files\/performance-drive-belt-tensioner-kit-for-chevrolet-silverado-3500-2001-2002-6-0l-1.jpg?v=1790739389","url":"https:\/\/performancechiptuning.com\/es\/products\/performance-drive-belt-tensioner-kit-for-chevrolet-silverado-3500-2001-2002-6-0l","provider":"Performance Chip Tuning","version":"1.0","type":"link"}
