Over time, original composite head gaskets deteriorate, yielding compression leaks across combustion chambers and coolant consumption. Compounding this, the factory plastic-faced timing chain guides embrittle and crack from thermal cycling, which bleeds off hydraulic tensioner pressure. Once chain slack occurs, erratic camshaft synchronization and jumped timing follow, risking dropped valve seats and terminal piston contact. Additionally, stock water pump bearings and internal seals wear out, causing rapid thermal spikes that warp aluminum cylinder heads.\u003c\/p\u003e\n\n\u003ch3\u003eThe Engineering Solution\u003c\/h3\u003e\n\u003cp\u003eThis master overhaul package addresses every primary failure point of the \u003cstrong\u003e4.7L PowerTech\u003c\/strong\u003e. Multi-Layer Steel (MLS) cylinder head gaskets deliver superior micro-sealing under high cylinder pressures and thermal expansion. Heat-treated, fatigue-resistant steel link chains paired with heavy-duty guide rails eliminate slap and resist stretching under load. A high-flow replacement water pump prevents localized coolant boiling, while new torque-to-yield head bolts are designed to ensure uniform clamping force across the deck. The included camshaft sprocket features the application-correct 30-tooth JTEC pattern to maintain precise crankshaft-to-camshaft phase correlation without triggering DTC misfire codes.\u003c\/p\u003e\n\n\u003ch3\u003eWhat's Included\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003e1 Multiple Layers Steel (MLS) Head Gasket\u003c\/li\u003e\n  \u003cli\u003e1 Valve Cover Gasket\u003c\/li\u003e\n  \u003cli\u003e1 Set of Valve Stem Seals\u003c\/li\u003e\n  \u003cli\u003e1 Intake Manifold Gasket\u003c\/li\u003e\n  \u003cli\u003e1 Exhaust Manifold Gasket\u003c\/li\u003e\n  \u003cli\u003e1 Front Camshaft Seal\u003c\/li\u003e\n  \u003cli\u003e1 Set of O-Rings\u003c\/li\u003e\n  \u003cli\u003e1 Package of Small Ancillary Gaskets\u003c\/li\u003e\n  \u003cli\u003e28 Cylinder Head Bolts (20 Long Bolts, 8 Short Bolts)\u003c\/li\u003e\n  \u003cli\u003e1 Lower Timing Chain (70 Links)\u003c\/li\u003e\n  \u003cli\u003e2 Secondary Timing Chains (106 Links each)\u003c\/li\u003e\n  \u003cli\u003e1 Right Secondary Tensioner\u003c\/li\u003e\n  \u003cli\u003e1 Left Secondary Tensioner\u003c\/li\u003e\n  \u003cli\u003e1 Primary Tensioner \u0026amp; Guide Plate Assembly\u003c\/li\u003e\n  \u003cli\u003e2 Tensioner Guide Rails\u003c\/li\u003e\n  \u003cli\u003e2 Fixed Guide Rails\u003c\/li\u003e\n  \u003cli\u003e1 Right Camshaft Sprocket (30 Teeth with JTEC Ring)\u003c\/li\u003e\n  \u003cli\u003e1 Left Camshaft Sprocket (30 Teeth without Ring)\u003c\/li\u003e\n  \u003cli\u003e1 Crankshaft Sprocket (25 Teeth)\u003c\/li\u003e\n  \u003cli\u003e1 Primary Idler Sprocket (50 Teeth)\u003c\/li\u003e\n  \u003cli\u003e1 Secondary Idler Sprocket (Dual 30\/30 Teeth)\u003c\/li\u003e\n  \u003cli\u003e1 Engine Water Pump\u003c\/li\u003e\n  \u003cli\u003e1 Engine Oil 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;\"\u003e2006-2007 Jeep Commander\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;\"\u003e4.7L PowerTech V8 \/ XK\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;\"\u003e235 hp \/ 305 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;\"\u003e53020827AB, HS26157PT-1, HS54237A, AW7163\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\u003e2006 Jeep Commander (XK) 4.7L V8\u003c\/li\u003e\n  \u003cli\u003e2007 Jeep Commander (XK) 4.7L V8\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 XK Commander?\u003c\/h4\u003e\n\u003cp\u003eYes, this is a direct fit for the 2006-2007 Jeep Commander equipped with the \u003cstrong\u003e4.7L PowerTech\u003c\/strong\u003e engine.
