Ready to rule out the possibility of blowing out your factory Y-bridge under high boost? Wehrli Custom Fabrication’s 3-inch Y-bridge kit for the LML Duramax does just that. In addition to replacing the stock Y-bridge with a larger, more durable version, offering a 3-inch diameter cold side intercooler pipe eliminates EGR, and vastly improves airflow. A new turbo inlet and coolant bypass kit is also included.
Each kit is hand fabricated and pre-fitted to ensure proper final fitment. All tubing is TIG welded and all flanges are CNC machined; with O-ring seals where necessary for a leak free seal. Kits are powder coated in the color of your choice (see available color options above). Perhaps the best part about this LML Y-Bridge kit is that it will work in conjunction with the twin turbo and single turbo kits we offer (S300 or S400), so you won't have to replace it or start all over when you decide to make future upgrades. Note: non-factory turbo requires upgraded VGT clamp.
