JK Dana 30/44 Bridge (OEM D30 & Rubicon D44). This bridge has been designed to use the stock OEM mount as a center support. Depending on application this support will be trimmed or can be left full height. You will weld the bridge to both driver side and passenger side axle tube, and the OEM driver side bushing mount. Welding to the center support gives it superior strength over a standard bridge. This bridge can be used with our new Pro Series 3 link kits, or our standard high clearance axle bracket kits. This bridge does NOT include any upper mount.
