Before: Stock bumper
(cut) After: Custom Bumper!
| In the
beginning…
I had always planned on building a custom front bumper capable of supporting a winch, but, I didn’t own a winch and for years, the stock bumper worked just fine. There were many other areas that got the attention of the customizer first. But, while returning from a trip to Moab UT in the spring of 2000, just 20 miles from my house, a deer decided to jump in front of me and take out the stock bumper. At least that was all the damage it did! Still, I left it smashed in for awhile, and then I finally just removed it and ran that way for awhile. My wife insisted I have a bumper on for towing a float in a local parade, so I did what I had seen certain Colorado rigs do and chopped the ends off the bumper, pounded what was left back into shape, and installed a shorty (see picture above). This was run for a short while 'till I finally got off my butt and built the solid piece of protection described below. J |

Previously built custom rear bumper
Custom front bumper (unpainted) I had previously modified the front fenders and fender flares to run flush with the bottom of the turn signal lights, so one of the design priorities was for the bumper to extend around the front of the turn signals and run back to the flares for protection of this vital fiberglass and plastic area. I also wanted the new bumper to tuck up high in the corners and angle back on the bottom center for clearance. The bumper needed to be able to mount a winch and I had an idea of how I would like to mount a winch to a plate that could mount to the front and back bumpers. I decided I wanted to mount the winch flat on top of the front bumper instead of to the front of the front bumper, yet it would need to mount flat to the face of the rear bumper. My plan was to make a right angle plate of 3/8" steel to which the winch would mount. This plate would then mount to the front bumper by sliding in two channels from the front and would install on the rear bumper (as described on http://www.jeepin.com) by sliding into some channels from the top. After making some measurements of the truck and various winches, checking out many other bumpers, and visualizing the new bumper, I started construction. |

Bumper brackets |
I had previously built some front tow points that mounted tow shackles (also on http://www.jeepin.com), so I decided to keep them and only mount the new bumper to the stock three mounting bolts on each side. I started by making some plates that extended out from these mounting plates. |
Bumper top from front

I trimmed them to mount a 2x2 angle iron piece directly in front of
the stock grill passing under it and down in front. Then I took a piece
of 1/4" plate and placed it across the mounting brackets providing a flat
spot 2" below the grill to mount the winch. This design keeps the winch
dropped a little below the grill to help with cooling and still allows
it to sit on top of the bumper protected from front obstacles. I extended
the flat plate a little past the mounting brackets and then mounted the
top rectangular tubing pieces to it. I took some 2x6x3/16" rectangular
tubing and ran it from the winch mount spot angled back towards and under
the grill. I then took some 2x3x3/16" rectangular tubing and mounted it
to the ends of the 2x6 stuff extending towards the flares while following
the angle of the fenders. I also trimmed the outside corner of this to
provide a more aesthetically pleasing corner.
Bumper top from front, bumper top from end, and bumper bottom welds show the completed top portion welded together. Even though I was being very careful, the ends of this piece managed to warp down a little from the welding heat. I decided to just leave the top alone as it wasn’t that bad, but if you are trying to fabricate something similar, BEWARE ! |
Bumper skid plate |
From here, I installed the top portion on the mounting brackets and trial fit the lower front piece, which had been bent at a local metal fabrication shop. This piece bolts to the front skid plate mounting locations, extends out some, and then angles up to the front edge of the winch plate (bumper skid plate ) If you look closely, you will see that there is a piece of 1x1/8" flat stock welded to this piece where it mounts to the skid plate bolts. This was done due to a mistake in the manufacture of the bent piece. It worked out well though because when the front skid plate is installed, the two 1/8" thick pieces match the thickness of the rest of the bent piece. While mocked up and adjusted to keep everything in line, the bent piece was tack welded to the winch plate and some angled brackets were tacked inside between the angled piece and the bottom of the winch plate. |
Right corner close-up |
From here, I trimmed the mounting plates to allow pieces of plate to run from the angled edges of the front skid piece up to the corners of the top piece. These were tacked in place and then the whole assembly was tacked to the mounting plates. At this point, I thought I was pretty much done. But after much study of the "finished" product, I decided to add some plates running from the bottom of the front skid plate to the corners of the top piece butting up against the front angled plates. (right corner close-up ) These pieces sort of finish the lower portion and keep a tow strap from hitting a sharp edge. The following pics show the fully welded bumper at this point: |

From here, I added two pieces of angle iron to the winch tray to form the channel for the winch tray to slide into. I also trimmed the wrap around ends more due to tire interference while flexed. I then ground all external welds smooth and used a belt sander to further smooth them. The bumper is a hefty piece with a weight of at least 90lbs, but should give good protection, mount a winch and not compromise too much approach angle. Finally, I gave the whole shebang a coat of rusty metal primer. I plan to coat the bumper with a bedliner product eventually, but for now, it is still rusty metal primer! J |
