2006-2010 Duramax LBZ/LMM Max Flow Bridge and Cold Side Tube Behind Alt (004-HSP)
The 004-HSP, or HSP Max Flow Bridge and Cold Side Tube with behind-alternator routing, is a game-changing upgrade for 2006-2010 Duramax trucks. By bundling our precision-built Y-bridge and high-flow cold side pipe, we've created a kit that dramatically improves airflow and performance.
Why You Need a Max Flow Bridge and Cold Side Tube
The factory bridge is notoriously restrictive, with poor airflow characteristics that create boost leaks and turbulence. HSP Diesel identified these weak points and built a superior solution that maximizes efficiency without sacrificing reliability or fitment.
What Makes the HSP Max Flow Bridge and Cold Side Tube Different?
We started by redesigning the bridge into a 3" two-piece construction that simplifies installation while offering outstanding performance. Precision CNC-machined, hand-fit, and sealed with an O-ring and dual M8 studs, this setup holds over 100 PSI with ease.
The 3" mandrel-bent cold side tube complements the bridge perfectly, reducing turbulence and improving spool-up. Together, these components unlock serious airflow gains and support higher horsepower while maintaining a factory-like fit and finish.
