Hooker BlackHeart application-specific LS swap engine mounting brackets eliminate the installation guesswork and compatibility uncertainty that comes with using universal swap plate mounting methods. These mounting brackets are available with dual engine mounting positions that optimize powertrain placement based on user-selected transmission, transfer case and driveshaft compatibility/retention priorities. The factory transmission crossmember is re-used with these mounting brackets (cost savings since driveshafts and crossmember are re-used). Factory LS Vortec exhaust manifolds can be used along with the engine mounting brackets and are required to support a street-legal engine change (with catalytic converters). Mounts feature a black powder-coated finish and Include (2) engine mounting brackets, attaching hardware and instructions.
