Factory plastic tensioner gaskets blow out under sustained oil pressure, bleeding off hydraulic tension to the timing chains. This drop in oil pressure leads to chain slack, causing severe chain slap against the guide rails until the nylon guides fracture and drop debris into the oil pickup tube. Concurrently, insufficient oil volume starves the \u003cstrong\u003eVCT solenoids\u003c\/strong\u003e and variable cam phasers, causing locking pin shear, erratic cam timing, rough idle, and severe misfires under load.\u003c\/p\u003e\n\n\u003ch3\u003eThe Engineering Solution\u003c\/h3\u003e\n\u003cp\u003eThis comprehensive service overhaul addresses critical oil starvation and tension loss at the root. The kit includes heat-treated, high-tensile steel timing chains (122 links) coupled with reinforced composite tensioner and guide rails designed to withstand extreme harmonic friction without cracking. New variable valve timing (\u003cstrong\u003eVCT\u003c\/strong\u003e) solenoids and upgraded camshaft phaser sprockets restore rapid, accurate oil flow modulation to maintain correct cam advance and retard cycles. Paired with a replacement oil pump and water pump, this kit restores oil pressure volume to safeguard top-end valvetrain components and stabilize valvetrain timing across the entire RPM band.\u003c\/p\u003e\n\n\u003ch3\u003eWhat's Included\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003e2 Timing Chains (122 Links \/ C-391)\u003c\/li\u003e\n  \u003cli\u003e2 Camshaft Phaser Sprockets\u003c\/li\u003e\n  \u003cli\u003e2 Cam Phaser Sprocket Mounting Bolts\u003c\/li\u003e\n  \u003cli\u003e1 Tensioner (Left Upper)\u003c\/li\u003e\n  \u003cli\u003e1 Tensioner (Right Upper)\u003c\/li\u003e\n  \u003cli\u003e1 Guide (Tensioner Rail-Left)\u003c\/li\u003e\n  \u003cli\u003e1 Guide (Tensioner Rail-Right)\u003c\/li\u003e\n  \u003cli\u003e1 Guide (Fixed Rail-Left)\u003c\/li\u003e\n  \u003cli\u003e1 Guide (Fixed Rail-Right)\u003c\/li\u003e\n  \u003cli\u003e1 Crank Gear (Double Row - One Side Recessed Only)\u003c\/li\u003e\n  \u003cli\u003e2 Camshaft Spacers\u003c\/li\u003e\n  \u003cli\u003e2 VCT Variable Camshaft Timing Solenoid Oil Control Valves (Left and Right)\u003c\/li\u003e\n  \u003cli\u003e2 Screws\u003c\/li\u003e\n  \u003cli\u003e2 Oil Control Valve Seals\u003c\/li\u003e\n  \u003cli\u003e1 Timing Cover Seal Set\u003c\/li\u003e\n  \u003cli\u003eTiming Cover Gaskets\u003c\/li\u003e\n  \u003cli\u003eValve Cover Gaskets\u003c\/li\u003e\n  \u003cli\u003e1 Oil Pump\u003c\/li\u003e\n  \u003cli\u003e1 Water Pump\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;\"\u003e2005-2011 Ford Expedition\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;\"\u003e5.4L Triton 3V SOHC V8 \/ U324 (also U222 2005-2006)\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 \/ 365 lb-ft (310 hp \/ 365 lb-ft from 2009+)\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;\"\u003e3L3Z6M280EA, 8L3Z6M280A, 8L3Z6M280B, 372930, 125-6050, 3R2Z-6A257-DA, 3L3E6C524FA, 917-250, 9L3Z-6600-A, 5L3Z-6268-A, XL3Z-6306-AA, F85Z-6K255-AA, 4L3Z-6M256-AA, F85Z-6M274-AA, 2L1Z-6K297-AA\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\u003e2005-2011 Ford Expedition 5.4L V8 SOHC 3-Valve (24-Valve)\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 U324 Expedition?\u003c\/h4\u003e\n\u003cp\u003eYes, this is a direct fit for the 2005-2011 Ford Expedition equipped with the \u003cstrong\u003e5.4L Triton 3V\u003c\/strong\u003e engine. \u003cstrong\u003eThis kit does not fit 2-valve (16-valve) 5.4L engines.\u003c\/strong\u003e\u003c\/p\u003e\n\n\u003ch4\u003eDoes this complete kit include the replacement water and oil pumps?\u003c\/h4\u003e\n\u003cp\u003eYes, both a replacement high-volume oil pump and mechanical water pump are included to ensure complete oiling circuit and cooling system restoration during the timing service.\u003c\/p\u003e\n\n\u003ch3\u003eThe Ford Heavy-Duty Standard\u003c\/h3\u003e\n\u003cp\u003eEngineered to handle the extreme cylinder pressures and thermal demands of heavy towing, this timing kit restores critical valvetrain stability and oil delivery to keep your full-size Ford working reliably under maximum load.\u003c\/p\u003e","brand":"VelocityMax","offers":[{"title":"Default Title","offer_id":68057576898808,"sku":"DS-E3V6JKB9K","price":269.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0800\/1290\/2648\/files\/performance-timing-chain-kit-for-ford-expedition-2005-2011-5-4l-1.jpg?v=1794345744","url":"https:\/\/performancechiptuning.com\/de\/products\/performance-timing-chain-kit-for-ford-expedition-2005-2011-5-4l","provider":"Performance Chip Tuning","version":"1.0","type":"link"}
