Paired with thermal cycling in the cramped engine bay of the \u003cstrong\u003eVortec 6000 LQ4\u003c\/strong\u003e, the stock idler pulley bearing grease breaks down, generating friction, audible pulley whine, and harmonic vibration. This loss of belt tension leads to micro-slippage across the water pump and alternator pulleys, compromising charging and cooling performance under load.\u003c\/p\u003e\n\n\u003ch3\u003eThe Engineering Solution\u003c\/h3\u003e\n\u003cp\u003eThis multi-piece kit replaces vulnerable wear components with heavy-duty alternatives engineered for severe service. The tensioner assembly features a high-grade torsional spring mechanism and a reinforced cast housing to maintain constant dynamic tension across all operating temperatures. The replacement idler pulley incorporates sealed precision bearings packed with high-temperature synthetic grease to resist axial play. Paired with a heavy-duty EPDM multi-rib belt (\u003cstrong\u003e6PK2360\u003c\/strong\u003e), this assembly resists rib cracking, high heat, and stretch under heavy 130-amp electrical loads.\u003c\/p\u003e\n\n\u003ch3\u003eWhat's Included\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003e1 Serpentine Belt (Part # 6PK2360)\u003c\/li\u003e\n  \u003cli\u003e1 Idler Pulley (Part # 38001)\u003c\/li\u003e\n  \u003cli\u003e1 Drive Belt Tensioner Assembly (Part # 38158)\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 2500 HD\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;\"\u003eVortec 6000 LQ4 \/ GMT800\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 2500 HD Base \/ LS \/ LT 6.0L V8 (130 Amp Alternator)\u003c\/li\u003e\n  \u003cli\u003e2002 Chevrolet Silverado 2500 HD Base \/ LS \/ LT 6.0L V8 (130 Amp 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 2500 HD?\u003c\/h4\u003e\n\u003cp\u003eYes, this is a direct fit for the 2001-2002 Chevrolet Silverado 2500 HD equipped with the \u003cstrong\u003eVortec 6000 LQ4\u003c\/strong\u003e engine. \u003cstrong\u003eNote: This kit is exclusively configured for models with the factory 130-amp alternator option; models equipped with the 105-amp alternator or dual-alternator setups require a different belt length and are excluded.\u003c\/strong\u003e\u003c\/p\u003e\n\n\u003ch4\u003eHow do I confirm if my truck has the 130-amp alternator?\u003c\/h4\u003e\n\u003cp\u003eVerify the RPO code label inside your glovebox for code KG8 (130-amp alternator) or measure the front pulley offset and case markings on your existing unit prior to installation.\u003c\/p\u003e\n\n\u003ch3\u003eThe Chevrolet Heavy-Duty Caliber\u003c\/h3\u003e\n\u003cp\u003eBuilt for the severe commercial duty demands of the heavy-duty Silverado platform, this accessory drive kit delivers the continuous torque transfer and thermal durability needed when towing heavy payloads over long grades without charging drops or cooling interruptions.\u003c\/p\u003e","brand":"VelocityMax","offers":[{"title":"Default Title","offer_id":67546951319800,"sku":"DS-EPWBG0IT7","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-2500-hd-2001-2002-6-0l-1.jpg?v=1790739355","url":"https:\/\/performancechiptuning.com\/es\/products\/performance-drive-belt-tensioner-kit-for-chevrolet-silverado-2500-hd-2001-2002-6-0l","provider":"Performance Chip Tuning","version":"1.0","type":"link"}
