Brothers Trucks Crossmember Exhaust Brackets
Lowering your truck is cool, but when you do, where are you going to put the exhaust--under the frame? You'll run out of room, real quick. Well, Brothers Trucks has the solution in their crossmember exhaust brackets. These kits include meaty steel components--brackets, bolts, and template—that allow modification of the factory trailing arm crossmember for dual exhaust. They are ideal options if you don't want to remove the crossmember and still be able to tuck the exhaust up inside the frame, and they are the perfect solution for someone that doesn't have access to a welding machine. The provided metal template allows perfect alignment for the bolt holes and exhaust cut out. It utilizes an existing hole in the crossmember to locate the template, then insert one of the supplied bolts, clamp in place, and mark the remaining holes for drilling. For the center hole, the hole in the template is larger to allow a plasma torch to be used as a guide, but if you don't have a plasma torch other means, such as a hole saw, can still be used to cut the hole. Get more clearance for exhaust without weakening your truck's frame when utilizing Brothers Trucks crossmember brackets. Features: * Exhaust tailpipes fit through the holes in the frame for easier installation and more ground clearance when adding dual exhaust * Fits rear wheel drive trucks with trailing arm and coil spring rear suspension * Steel construction * Allows up to 3 in. dual exhaust system * Includes two pre-welded cut-out pieces, drilling template, and Grade 8 fasteners
