Bumper -- Late reply...
Paul and others,
Sorry for the late reply. I will be happy to share the specs with you. I'll be out in CA for the Truckhaven run. I'll get someone to take some good digital pics while we are out there. I have a scanner but I haven't picked up a digital camera yet...soon.
We can measure the heck out of the thing. The angles are quite simple. Most metal shops should be able to make the two bends. I believe we are dealing with one right angle and one 45 degree angle,(I'll double check). High Country Performace 4x4 built the bumper for me.
The bumper started life as three pieces. Two side panels and the long rear panel. They were custom fitted at High Country. High Country had a metal shop bend the initial sheet metal. They used 13/16 thick metal. 1/8 too thin 1/4 too heavy. There are supports bars welded on the inside corners to give the side panels more support. The class III receiver will not tow big loads. I had that added for a tow point on the trail and to tow jetski/motorcycle trailers. I would NOT tow a heavy boat or car trailer.
Bumper mounts to stock frame mounting points. The bumper was made to accomodate a 33 inch tire in the stock mounting location. The rear most frame rail must be "edited" to allow the 33 to fit. We used a plasma cutter but a saws-all should do the trick. The stock bumper would no longer fit on the Explorer with a 33 inch tire mounted under as a spare. I have some pics of the tire mounted without the bumper. I'll scan them in.
Pinch molding was used on the edges of the cut quarter pannel to give a more finished look.
Storage...no room...
..
This was one of the gotta haves for me when I started. I actually wanted the bumper to be a box. I thought the top could open...turns out with that 33 under there it does not leave much room. You could get it done but then your bumper will start to stick out eating into you depature angle. I don't believe I drasticlly improved my departure angle but I don't think that I have hurt it.
I may add some backup lights in the future.
I was hoping to have the bumper today...but the paint shop is a little behind...
more to come...
