The LB7 3" Y-Bridge is an upgraded high flow intake bridge for the 2001-2004.5 LB7 Duramax. The OEM LB7 Y-bridge measure’s only 2 3/8” ID, our fabricated bridge is 3" and we use an HD machined beadroll where the T-bolt clamps so there is no concern for the pipe to crush. Experience increased turbo spool up and throttle response. Must be used inconjuction with aftermarket 3" Cold Side Intercooler Pipes, not compatible with the OEM intercooler pipe. Will work with the OEM or any OEM type turbocharger with WCFab or OEM turbo inlet horn. Also compatible with our s300 or s400 Single turbo kits.
