Why add a y-bridge kit to your Duramax? The LBZ/LMM 3" Y-Bridge Kit is an upgraded high flow intake kit for the 2006-2010 Duramax. The factory Y-bridge is a poorly designed two piece bridge that is prone to blowing apart under boost and creating poor drivability and excessive smoke. This is a one piece fabricated 3" bridge with a heavy duty machined bead roll on the end so the pipe cannot deform when the t-bolt clamp is tightened. A 3" high flow intercooler pipe compliments the y-bridge to offer a full 3" tract from intercooler to engine. This 3" Y-Bridge kit will work in conjunction with Wehrli's S400 over stock Twin Turbo Kit if you decide to upgrade in the future.


Illusion Cherry, Gloss Black, and Gloss white is all we have available and do not have the ability to get any other colors. If you want a different color, grab a kit and get it repowder coated. We have done this several times and any powder coat shop can easily do that.


Included in this kit you will receive,


Full 3" Y Bridge

Cold side piping

3" coupler

x2 T bolt clamps

Hardware pack with clamps, gaskets, coolant hose, and NPT plug.
