Thin factory plastic tensioner gaskets blowout under load, leaching crucial oil pressure away from the cylinder heads. Starved of hydraulic volume, OEM cam phasers flutter, break internal locking pins, and cause destructive chain slap against the nylon guide rails. This plastic debris drops into the oil pan, restricting the pickup tube and leading to catastrophic valvetrain desynchronization, severe timing retardation, and piston-to-valve contact.\u003c\/p\u003e\n\n\u003ch3\u003eThe Engineering Solution\u003c\/h3\u003e\n\u003cp\u003eThis master timing system addresses OEM hydraulic decay by pairing heat-treated, high-tensile alloy steel chains with rigid tensioner arms and upgraded cast-body tensioners that maintain steady mechanical tension even during low-RPM oil pressure drops. The kit incorporates revised variable cam timing (VCT) solenoids, high-flow oil control valve seals, and balanced phaser sprockets engineered to prevent internal vane shear. Complemented by a high-pressure oil pump to sustain critical galley volume and a high-flow water pump to combat thermal load, this kit completely resolves the inherent cam phaser tick and premature stretch common to heavy-duty towing applications.\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;\"\u003e2005-2010 Ford F-250\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 3-Valve V8 \/ P221 Platform\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\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\u003e2005-2010 Ford F-250 Super Duty 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 P221 F-250?\u003c\/h4\u003e\n\u003cp\u003eYes, this is a direct fit for the 2005-2010 Ford F-250 equipped with the \u003cstrong\u003e5.4L 3-Valve SOHC Triton V8\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\u003eAre both the oil pump and water pump included in this kit?\u003c\/h4\u003e\n\u003cp\u003eYes, both a replacement oil pump and water pump are included alongside all required gaskets, seals, and hardware to ensure complete front-engine service.\u003c\/p\u003e\n\n\u003ch3\u003eThe Ford Super Duty Standard\u003c\/h3\u003e\n\u003cp\u003eWhen pulling heavy payloads or tackling high-stress commercial duty cycles, your Super Duty demands unflinching valvetrain stability and sustained oil volume under extreme thermal conditions.\u003c\/p\u003e","brand":"VelocityMax","offers":[{"title":"Default Title","offer_id":68057582928120,"sku":"DS-EQ6ASGLMB","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-f-250-2005-2010-5-4l-1.jpg?v=1794345787","url":"https:\/\/performancechiptuning.com\/fr\/products\/performance-timing-chain-kit-for-ford-f-250-2005-2010-5-4l","provider":"Performance Chip Tuning","version":"1.0","type":"link"}
