Under prolonged elevated boost pressure and high exhaust gas recirculation (EGR) thermal cycles, the factory rubber boots suffer from oil degradation and heat-soak fatigue, causing delamination, split seams, or full blow-offs under towing load. Furthermore, factory necked-down pipe bends introduce severe airflow turbulence and boundary-layer separation, resulting in measurable charge-air pressure drops, elevated EGTs, and ECM-induced limp-mode events due to underboost DTC codes.\u003c\/p\u003e\n\n\u003ch3\u003eThe Engineering Solution\u003c\/h3\u003e\n\u003cp\u003eEngineered for sustained heavy-duty operation, this direct-fit charge pipe assembly features full 3-inch mandrel-bent polished aluminum tubing that maintains uniform internal cross-sectional diameter from turbo discharge to intake manifold. By eliminating corrugated flex sections and factory pinch points, charge-air velocity is preserved with negligible delta-P loss. The system utilizes heavy-duty reinforced multi-ply silicone boots that resist permeation from aerosolized crankcase oil and withstand continuous operating temperatures above 400°F. High-tensile stainless steel T-bolt clamps provide 360-degree radial clamping tension, mechanically locking the couplers to beaded pipe ends to prevent blow-offs under high-boost conditions.\u003c\/p\u003e\n\n\u003ch3\u003eWhat's Included\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003eHot side intercooler pipe\u003c\/li\u003e\n  \u003cli\u003eCold side intercooler pipe\u003c\/li\u003e\n  \u003cli\u003eReinforced intercooler boots and couplers\u003c\/li\u003e\n  \u003cli\u003eStainless steel T-bolt clamps\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;\"\u003e2011-2016 GMC Sierra 2500 HD \/ 3500 HD\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\u003eDuramax LML\u003c\/strong\u003e \/ \u003cstrong\u003eGMT900\u003c\/strong\u003e \u0026amp; \u003cstrong\u003eK2XX\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;\"\u003e397 hp \/ 765 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;\"\u003e\u003cstrong\u003eDAT000000017\u003c\/strong\u003e\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\u003e2011-2016 GMC Sierra 2500 HD 6.6L Duramax LML Diesel\u003c\/li\u003e\n  \u003cli\u003e2011-2016 GMC Sierra 3500 HD 6.6L Duramax LML Diesel\u003c\/li\u003e\n  \u003cli\u003e2011-2016 Chevrolet Silverado 2500 HD 6.6L Duramax LML Diesel\u003c\/li\u003e\n  \u003cli\u003e2011-2016 Chevrolet Silverado 3500 HD 6.6L Duramax LML Diesel\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 GMT900 \u0026amp; K2XX Sierra?\u003c\/h4\u003e\n\u003cp\u003eYes, this is a direct fit for the 2011-2016 GMC Sierra equipped with the \u003cstrong\u003eDuramax LML\u003c\/strong\u003e engine; it does not fit older LBZ\/LMM platforms or later L5P configurations.\u003c\/p\u003e\n\n\u003ch4\u003eWhat are the critical installation steps to prevent boot blow-off?\u003c\/h4\u003e\n\u003cp\u003eThoroughly degrease the turbocharger outlet and intercooler hose beads with isopropyl alcohol prior to installing the reinforced silicone boots, and torque all T-bolt clamps evenly before performing a post-drive torque inspection.\u003c\/p\u003e\n\n\u003ch3\u003eThe GMC Heavy-Duty Standard\u003c\/h3\u003e\n\u003cp\u003eHeavy-duty commercial towing requires uncompromising structural integrity across the entire induction system.
