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 slip-in style two piece bridge with very little support that is prone to blowing apart under boost and creating poor drivability and performance. This kit is a much improved, high flow, bolt together style two piece 3" bridge. A 3" high flow inter cooler pipe compliments the y-bridge to offer a full 3" tract from inter cooler to engine.

2010 LMM and some 2009 will require Map sensor Seal which we include in the kit.
