So I wanted to make a different style of high clearance rear bumper and wanted it to match my future tubular front bumper and also wanted the utility of dual swing outs. After tedious measurements, and hours upon hours of computer modeling, I believe I created a sharp looking design that was also functional and as high clearance as I could get it.

I first started by cutting off the rear cross member and then about another 1/2" off of the rear frame members.

I cut down all the way to where the welds were for the captured nuts and then ground down everything and then painted everything.

I cut out some frame mounts on the waterjet from 3/8" steel.

The frame mounts use the captured M14 x 1.5 nuts on the frame rails (8 on the bottom and 4 on the outboard sides)

I then welded on the central tube made from 2 x 4 x 3/16" tubular rectangular tubing. The central tube contours the rear of the vehicle. I also streamlined the corners that could possibly smack against rocks (something I've observed on other bumpers). This tube also supports the swingouts. The spindles (from 4x4 labs) are welded on the inside and outside.

The hitch is welded onto the central tube and then supported by a cross member to beef everything up.

The tow points are cut from 1" steel and welded on the central tube, frame mount, and the cross member.

I then welded up the rest of the tube work on the center section of the bumper so that it would be even with the bottom of the frame.

For a chain plate, I decided to tie the hitch into the lower round tube. I added holes on the sides for a chain. I don't quite know if this will work 100% but if it does not, I will just drill some holes in the hitch gussets (where it attaches to the crossmember) and call it good. I also added a set screw to the hitch so that when I need to carry something in there that I do not want to rattle around I have the option.

Next came the wings to protect my rear quarter panels. All of the round tubing is 1.5" x 11 ga.

I designed the wings so that they hug the side of the vehicle as close as possible while still providing the most ground clearance possible. I also positioned the tubes along the wing to ensure that the different parts of the body would be adequately protected and that if a rock were to come into contact with the bumper, it would slide easily to the rear of the vehicle.

By the way, all cantilever members and members with a possible side load were gusseted in atleast 2 locations and on different planes if needed.

Tire Swingout

I decided to put the tire on the driver's side due to visibility reasons. I made sure to include many tabs for reverse lights, backup cameras, and antennas on both swingouts. The tire carrier is adjustable for different offset wheels and different width tires. There are uhmw strips in certain locations on the tire carrier for the tire to rest against. This helps to keep the paint from rubbing off while keeping the tire from bouncing up and down. I designed it to carry up to a 37" tire but it could probably go larger for whatever reason. The tire carrier also carries a hilift jack as well. The jack that I have is a 60" jack so it sits above the roof quite a bit. However, the mounting for the jack is very secure and can take hits (as I have already done when trying to back into my garage :doh:). Any other jack length will fit and you only have to loosen one nut to get it off. The tire swingout also has an integrated hitch. My main plan for this is to modify my thule bike carrier to fit this arrangement (thanks to davegonz for this idea). I also can use it to hold a cargo rack for more storage. The hitch has a set screw to ensure that whatever is hitched up will not rattle around.

Made sure to keep everything tucked in as close to the body as possible

Ladder Swingout

As for the ladder/ utility swingout, I wanted to make it modular. The swingout arms are made from 2 x 3 x 3/16" rectangular tube and the round tubing is all 1.5 x 11ga.

I decided that I would like to carry 3 jerry cans back there so I designed and built a holder that would accommodate this.

The carrier slips onto the ladder rack and is held on by 4 bolts.

IMG_0418_zps966b89af.jpg


I added some artwork to the holder as well.

IMG_0390_zpsbc68a74b.jpg


I added e-track type strap hooks to hold the cans down. Don't have the proper straps yet but they are on the way.

IMG_2824_zpsb6cdf92f.jpg


As with the bumper, all of the cantilever members are properly gusseted.

IMG_2822_zps7b5d5c25.jpg


Using some quick fists, I mounted a shovel to the swingout as well.

IMG_0407_zps3a5bed0d.jpg


I got some latches from mcmaster to hold everything down tight. The bumpers next to the latches keep everything rattle free. The swingouts are held open by gas springs.

IMG_2826_zps48ace7b2.jpg


I finished everything up with Duplicolor self etching primer with filler and then a few coats of duplicolor graphite wheel paint.

Tubular Dude! Nice Writeup! I got to see this thing first hand and it looks absolutely beautiful! High clearance, stout and unique. You sir, are a true artist. ;)
 
Very artistic....just like your front fender...;)....this bumper is really cool, saw it in person and it is awesome. The 100 accessories are multiplying...good to see nice work like this.

Thanks Jon! Had a blast on the trip! Thanks again for putting that together. PM sent.

I think I finally finished the write up and let me know if you have any questions.
 
Good golly; what does that thing way?!

Funny you ask, I meant to weigh it, however, I didn't. I can pick it up and put it on by myself (minus swingouts). I can't imagine it weighing anything more than the plate style bumpers out there.
 
Awesome work and killer set of tools!
 
That has got to be beefier than any 3rd party mainstream bumper.

Awesome work.
 
so when are they going to be for sale?
 
That is the most complicated rear bumper I have seen. There is a lot of stuff going on. However I really like it. Well done sir! I have been wanting to do something very similar, only without the tube section on the bottom, and chop the frame at a 45* angle upward to meet the main bar. Not sure what would happen structurally without the tube bracing.
 
Thanks guys and great pictures loud!

One other thing that I did, like my sliders, I plumbed all of the major tubes so that I can use them as air tanks in the future when I join the club and get a compressor.
 
seriously though, is there any thought of producing this for others? What do you do for a day job that you have the equipment and skill on hand.

I am in the Air Force waiting to go to pilot training. Currently I work in the mechanical engineering department where we have the ability and machinery to produce formula style race cars and baja style off road vehicles. All of the design and fabrication was done by myself afterhours.

I would like this bumper to be produced. Currently I am talking to fab shops that frequent this forum to try and convince them to produce it. The more serious interest you guys show in it, the more likely it will be produced.
 
Wow. Hats off to you for the effort and execution. I would love to have the time and tools as my disposal.

Don't take this the wrong way, but I do wonder if the beefiness was overdone.
