On the high-revving \u003cstrong\u003eK24A2\u003c\/strong\u003e, this mechanical fatigue introduces excessive belt deflection and harmonic vibration. As the factory damping degrades, the serpentine belt loses uniform grip against the alternator, water pump, and A\/C compressor pulleys. This yields belt slip during rapid throttle transitions, premature failure of internal pulley bearings, accelerated rib wear, and audible squeal under electrical or mechanical accessory load.\u003c\/p\u003e\n\n\u003ch3\u003eThe Engineering Solution\u003c\/h3\u003e\n\u003cp\u003eThis replacement kit resolves accessory drive instability by utilizing a reinforced cast-aluminum tensioner housing paired with a fatigue-resistant internal spring calibrated to withstand aggressive engine speeds. The assembly integrates a precision-machined idler pulley running a high-grade, sealed double-row ball bearing to handle radial loads and prevent thermal seizure. Included is a multi-rib \u003cstrong\u003e7PK1755\u003c\/strong\u003e synthetic EPDM serpentine belt engineered for high tensile strength, resistance to heat cracking, and optimal friction contact to maintain synchronized accessory rotation up to the 7,100 RPM redline.\u003c\/p\u003e\n\n\u003ch3\u003eWhat's Included\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003e1 Serpentine Belt (7PK1755)\u003c\/li\u003e\n  \u003cli\u003e1 Tensioner Assembly\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;\"\u003e2004-2006 Acura TSX\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;\"\u003e\n\u003cstrong\u003eK24A2\u003c\/strong\u003e \/ \u003cstrong\u003eCL9\u003c\/strong\u003e\n\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;\"\u003e200 hp \/ 166 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;\"\u003eN\/A\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\u003e2004 Acura TSX Base 2.4L L4 Gas (K24A2)\u003c\/li\u003e\n  \u003cli\u003e2005 Acura TSX Base 2.4L L4 Gas (K24A2)\u003c\/li\u003e\n  \u003cli\u003e2006 Acura TSX Base 2.4L L4 Gas (K24A2)\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 CL9 TSX?\u003c\/h4\u003e\n\u003cp\u003eYes, this is a direct fit for the 2004-2006 Acura TSX equipped with the \u003cstrong\u003eK24A2\u003c\/strong\u003e engine.\u003c\/p\u003e\n\n\u003ch4\u003eDo I need a special tool to relieve tension during installation?\u003c\/h4\u003e\n\u003cp\u003eInstallation requires a standard serpentine belt tool or long-handled box wrench on the tensioner cast lug to compress the internal spring and route the belt.\u003c\/p\u003e\n\n\u003ch3\u003eThe Acura Caliber\u003c\/h3\u003e\n\u003cp\u003eThe high-compression VTEC valvetrain on the \u003cstrong\u003eK24A2\u003c\/strong\u003e demands rock-solid accessory drive stability; this kit provides the mechanical reliability required to maintain uninterrupted accessory output throughout aggressive driving.\u003c\/p\u003e","brand":"VelocityMax","offers":[{"title":"Default Title","offer_id":67547090616568,"sku":"DS-EU5UHJLPV","price":75.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0800\/1290\/2648\/files\/performance-drive-belt-tensioner-kit-for-acura-tsx-2004-2006-2-4l-1.jpg?v=1790740331","url":"https:\/\/performancechiptuning.com\/fr\/products\/performance-drive-belt-tensioner-kit-for-acura-tsx-2004-2006-2-4l","provider":"Performance Chip Tuning","version":"1.0","type":"link"}
