In commercial haulers running the \u003cstrong\u003eVortec 4800 (LR4)\u003c\/strong\u003e or \u003cstrong\u003eVortec 6000 (LQ4)\u003c\/strong\u003e, thermal cycling and torsional harmonics stretch the link plates. This elongation causes camshaft retard, erratic ignition events, and excessive timing slack. Over time, worn sprockets and stretched links trigger cam\/crank correlation diagnostic trouble codes (DTC P0341) and increase the risk of tooth skipping or complete valvetrain collision.\u003c\/p\u003e\n\n\u003ch3\u003eThe Engineering Solution\u003c\/h3\u003e\n\u003cp\u003eThis direct-fit timing chain kit replaces fatigued factory components with a precision-machined assembly engineered for Gen III small-block architectures. Utilizing hardened steel construction for both the crankshaft and camshaft sprockets, it maintains exact tooth engagement under aggressive acceleration and towing stress. The pre-stressed, high-tensile link chain limits dynamic whipping and resists stretching. Designed specifically for \u003cstrong\u003e24X reluctor\u003c\/strong\u003e configurations, this setup ensures rock-solid ignition mapping and exact cam timing across the entire powerband.\u003c\/p\u003e\n\n\u003ch3\u003eWhat's Included\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003e1 Timing Chain\u003c\/li\u003e\n  \u003cli\u003e1 Camshaft Sprocket\u003c\/li\u003e\n  \u003cli\u003e1 Crankshaft Sprocket\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;\"\u003e2003-2007 GMC Savana 2500,3500\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;\"\u003e4.8L LR4, 6.0L LQ4 \/ GMT610\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;\"\u003e285-300 hp \/ 295-360 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;\"\u003eTS4194A\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\u003e2003-2007 GMC Savana 2500 4.8L V8 (24X Reluctor)\u003c\/li\u003e\n  \u003cli\u003e2003-2007 GMC Savana 2500 6.0L V8 (24X Reluctor)\u003c\/li\u003e\n  \u003cli\u003e2003-2007 GMC Savana 3500 4.8L V8 (24X Reluctor)\u003c\/li\u003e\n  \u003cli\u003e2003-2007 GMC Savana 3500 6.0L V8 (24X Reluctor)\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 GMT610 Savana 2500,3500?\u003c\/h4\u003e\n\u003cp\u003eYes, this is a direct fit for the 2003-2007 GMC Savana 2500,3500 equipped with the \u003cstrong\u003e4.8L LR4\u003c\/strong\u003e or \u003cstrong\u003e6.0L LQ4\u003c\/strong\u003e engine utilizing a 24X reluctor wheel. \u003cstrong\u003eThis kit does not fit 58X reluctor engines or 2008+ Gen IV platforms.\u003c\/strong\u003e\u003c\/p\u003e\n\n\u003ch4\u003eDo I need to verify sprocket tooth counts before installation?\u003c\/h4\u003e\n\u003cp\u003eYes, always verify tooth count and link profile against your removed core to confirm 24X Gen III cam gear alignment prior to final assembly.\u003c\/p\u003e\n\n\u003ch3\u003eThe GMC Heavy-Duty Commercial Standard\u003c\/h3\u003e\n\u003cp\u003eEngineered to handle the brutal, continuous torsional loads of commercial fleet hauling and heavy payload transport, this timing set provides the durable valvetrain reliability required to keep your work van on the road without breakdown.\u003c\/p\u003e","brand":"VelocityMax","offers":[{"title":"Default Title","offer_id":67545332383992,"sku":"DS-E7CH3560B","price":81.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0800\/1290\/2648\/files\/performance-timing-chain-kit-for-gmc-savana-2500-3500-2003-2007-4-8l-6-0l-1.jpg?v=1790721874","url":"https:\/\/performancechiptuning.com\/products\/performance-timing-chain-kit-for-gmc-savana-2500-3500-2003-2007-4-8l-6-0l","provider":"Performance Chip Tuning","version":"1.0","type":"link"}
