I was watching the Extreme 4x4 show on Spike the other day and they were showing an episode from the Urban Gorilla build or maybe its the Surburban Gorilla. Anyway, for those not in the know, they are spending a dump truck load of money to over build a Suburban. I am guessing its gonna be over $100,000 by the time they are finished. They are taking an old Suburban frame, putting on an aftermarket Hummer body, I don't recall the axles but its probably a D60 and 14BFF. The drive train has got to be over 35 grand. They are using a crate Duramax with a one off custom Banks dual turbo set up, an Allison 1000 that is custom overbuilt, an a 203/205 doubler. The entire drive train looks like its about 15 feet long. Anyway on the show I saw, they were working on the frame. They boxed it and put in suspension and drive train mounts. They lifted in the Duramax with the Allison on it, minus the TCs, to fab up the mounts. For the tranny cross member they did something I haven't seen before. They took a piece of tube, 1.75 or 2.00, and gave it a slight upward bend on each end. Then they notched the ends and welded in short pieces, ( 2 to 2.5 inch long), of tubing for bushing eyes. They used Prothane poly bushings like you would use in a spring eye. Then they welded two tabs to the inside of the frame on each side, keeping in mind, the frame was boxed. Then they just bolted it in and the Allison sat on top of it. There was no word if the cross member was bolted directly to the tranny or if they used an additional poly mount in between. I know a ladder frame is supposed to flex, this is why the crossmembers are riveted in and not welded. But isn't this too much flex? It appears they left the stock engine cross member intact, but I assume they are going to do the same for the crossmember(s) they use for the doubler. This means that even tho they boxed the frame, there isn't a crossmember that directly bolts to the side rails from the engine cross member all the way back to the one that is just in front of the rear axle. An it looked like they were taking that out at some point. Any comments or thoughts on this design?
