This complete HSP Y-Bridge kit combines a precision-built Y-bridge with a mandrel-bent cold side intercooler tube to reduce factory restrictions and improve airflow, reliability, and overall performance.\u003c\/p\u003e\n\u003ch3\u003eWhy You Need an HSP Y-Bridge for LBZ \u0026amp; LMM Duramax\u003c\/h3\u003e\n\u003cp\u003eThe factory Duramax Y-bridge is known for restrictive airflow, inconsistent sealing, and boost leaks that limit performance. The HSP Y-Bridge for LBZ and LMM Duramax engines was designed to correct these issues by improving airflow efficiency while maintaining OEM-style fitment.\u003c\/p\u003e\n\u003ch3\u003eWhat Makes the HSP Max Flow Y-Bridge Kit Different?\u003c\/h3\u003e\n\u003cp\u003eThe HSP Y-Bridge features a 3-inch, two-piece CNC-machined design that simplifies installation while delivering consistent airflow and reliable sealing. Each bridge is hand-fit and sealed using an O-ring and dual M8 studs, allowing it to hold over 100 PSI of boost without failure.\u003c\/p\u003e\n\u003cp\u003ePaired with the bridge is a 3-inch mandrel-bent cold side intercooler tube routed behind the alternator. This design reduces turbulence, improves turbo spool-up, and enhances throttle response while maintaining a factory-style engine bay layout.\u003c\/p\u003e\n\u003ch3\u003eWhat's Included in the HSP Y-Bridge Kit\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e1x Bridge Section (HSP-IN-220)\u003c\/li\u003e\n\u003cli\u003e1x Cold Side Tube Behind Alternator (HSP-IN-202)\u003c\/li\u003e\n\u003cli\u003e1x Bridge Neck (HSP-IN-743-2)\u003c\/li\u003e\n\u003cli\u003e1x Bridge Neck O-Ring (RFB-670-RFAB)\u003c\/li\u003e\n\u003cli\u003e1x 1\/8\" NPT Brass Plug (RFB-811-RFAB)\u003c\/li\u003e\n\u003cli\u003e2x Bridge Neck Studs (RFB-902-RFAB)\u003c\/li\u003e\n\u003cli\u003e2x Bridge Neck 12-Point Nuts (RFB-903-RFAB)\u003c\/li\u003e\n\u003cli\u003e24\" 5\/8\" Heater Hose (RFB-401-RFAB)\u003c\/li\u003e\n\u003cli\u003e2x 5\/8\" Worm Gear Clamps (RFB-403-RFAB)\u003c\/li\u003e\n\u003cli\u003e4x 3\" T-Bolt Clamps (RFB-422-RFAB)\u003c\/li\u003e\n\u003cli\u003e2x 3\"x4\" Straight Silicone Boots (RFB-430-RFAB)\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eFitment – LBZ \u0026amp; LMM Duramax\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eLBZ: 2006-2007 (VIN Code 2 or D)\u003c\/li\u003e\n\u003cli\u003eLMM: 2007.5-2010 (VIN Code 6)\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e\u003cem\u003eNote:\u003c\/em\u003e Engine code is the 8th character of the VIN; model year is the 10th character.\u003c\/p\u003e\n\u003ch3\u003eOverview\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eIncreased airflow and performance\u003c\/li\u003e\n\u003cli\u003eFaster turbo spool-up\u003c\/li\u003e\n\u003cli\u003eTwo-piece Y-bridge design for improved fitment\u003c\/li\u003e\n\u003cli\u003eMandrel-bent cold side tube to reduce turbulence\u003c\/li\u003e\n\u003cli\u003e3-inch diameter piping throughout\u003c\/li\u003e\n\u003cli\u003eMultiple color and custom coating options\u003c\/li\u003e\n\u003cli\u003eFactory-style routing compatible with drop-in turbochargers\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eSpecial Note\u003c\/h3\u003e\n\u003cp\u003eThis Y-Bridge and cold side tube kit is best suited for factory or drop-in replacement turbochargers, as it follows OEM-style intercooler routing.\u003c\/p\u003e\n\u003ch3\u003eOur Warranty\u003c\/h3\u003e\n\u003ch4\u003eHSP NO BS LIMITED LIFETIME WARRANTY\u003c\/h4\u003e\n\u003cp\u003eAt HSP Diesel, we stand behind every product we manufacture.
