As mileage accumulates, mechanical chain stretch induces camshaft-to-crankshaft timing retard, degrading bottom-end torque, destabilizing idle quality, and causing erratic cam sensor correlation trouble codes (P0016 \/ P0341). Furthermore, excessive slack allows chain whip against the front timing cover, accelerating sprocket tooth wear on high-mileage commercial vans.\u003c\/p\u003e\n\n\u003ch3\u003eThe Engineering Solution\u003c\/h3\u003e\n\u003cp\u003eThis heavy-duty timing set is engineered with precision-machined, induction-hardened iron sprockets and a pre-stretched, high-tensile link chain to resist fatigue under load. Manufactured to \u003cstrong\u003eTS4194A\u003c\/strong\u003e dimensional specifications, it ensures exact tooth engagement across the crankshaft gear and 3-bolt camshaft gear. Designed specifically for \u003cstrong\u003e24X reluctor\u003c\/strong\u003e Gen III engine configurations, it delivers reliable timing synchronization, maintaining zero valve lash overlap variance and sustaining peak volumetric efficiency under severe towing conditions.\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 (3-Bolt Pattern)\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 1500\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;\"\u003eGen III Vortec (LR4 \/ LM7 \/ 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;\"\u003e285-295 hp \/ 325-335 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 1500 4.8L V8 (24X Reluctor)\u003c\/li\u003e\n  \u003cli\u003e2003-2007 GMC Savana 1500 5.3L V8 (24X Reluctor)\u003c\/li\u003e\n  \u003cli\u003e2003-2007 GMC Savana 1500 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 1500?\u003c\/h4\u003e\n\u003cp\u003eYes, this is a direct fit for the 2003-2007 GMC Savana 1500 equipped with the \u003cstrong\u003eGen III LS-series V8\u003c\/strong\u003e engines (4.8L, 5.3L, 6.0L) utilizing a \u003cstrong\u003e24X reluctor\u003c\/strong\u003e wheel. \u003cstrong\u003eDoes not fit late-model Gen IV engines featuring 58X reluctor wheels or single-bolt camshafts.\u003c\/strong\u003e\u003c\/p\u003e\n\n\u003ch4\u003eDo I need to degree the camshaft when installing this timing set?\u003c\/h4\u003e\n\u003cp\u003eThis direct-fit kit aligns via standard factory dot-to-dot timing marks and does not require custom degreeing when paired with stock or OEM-replacement camshafts.\u003c\/p\u003e\n\n\u003ch3\u003eThe GMC Commercial Standard\u003c\/h3\u003e\n\u003cp\u003eEngineered to handle the continuous duty cycles of cargo hauling and heavy trailer towing, this timing assembly restores bulletproof valvetrain stability to your GMT610 workhorse.\u003c\/p\u003e","brand":"VelocityMax","offers":[{"title":"Default Title","offer_id":67545331564792,"sku":"DS-EQM5PTZN8","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-1500-2003-2007-4-8l-5-3l-6-0l-1.jpg?v=1790721850","url":"https:\/\/performancechiptuning.com\/products\/performance-timing-chain-kit-for-gmc-savana-1500-2003-2007-4-8l-5-3l-6-0l","provider":"Performance Chip Tuning","version":"1.0","type":"link"}
