Bump It Offroad – (Bolt-On) Rear Bumper Group Buy May 2013

I'd also be interested in some pix from the GB bumpers, and am interested in a second round. Anyone else interested in a 2014 May BIOR rear bumper GB?

For the pix, can you guys show us some of the enhancements/differences you asked for in your bumpers?
 
I'll have to post detailed photos since you can't tell in this one.

I got:
  • Upgraded spindles
  • Struts
  • 10.9 and Grade-8 hardware
  • 60% gloss powder coating (scratches very easily but touches up well with Rustoleum satin black)
  • Capped ends. He didn't really cap them though :(. But it does probably add some rigidity
  • Dual can carrier from @Newps powdercoated to match with a light tab on top
  • Adjustable tire carrier. The verticle adjustability is kind of dumb. I have it set to the second highest setting, and my 295/75/16 barely clears the bottom of the swing out. The in/out adjustability is nice and the overall design seems better than the Slee or non-adjustable one.
  • Spare spindle sleeve/cover. I'm currently only running the tire carrier.
  • Local powdercoater did a rust preventing epoxy coating that worked great. I scratched the hell out of the bumper in Moab. Waited two weeks to touch up the paint and almost no rust. I wish the WKOR sliders were that rust proof.
Overall the bumper saved the 100's ass countless times on our Los Angeles to Moab "expedition" through some gnarly trails. And White Rim Trail managed to not rattle the thing apart. It was super useful for carrying things. The strut worked well as a place to keep the propane cylinder while cooking.

I used it to carry the following things:
  • 5 gallons of water
  • 5 gallons of gasoline
  • Shovel
  • Ax
  • Trasharoo
  • Spare Trasharoo
  • 4lbs of propane
  • Front Runner flip pop tent
  • Siphon

Klaus, thanks very much, it really does look like a great bumper - and a great trip too.
I am not sure what you meany by strut? The gas strut that controls the swing outs?
I was hoping to use the adjustable height of the spare wheel to push it lower to improve rear window visibility.
Any concerns with brake and indicator lights being blocked?

Anybody else interested in a GB this summer? Perhaps I should start a thread after checking in with BIOR?
 
I maybe interested in the GB - pending final price and delivery date... also have a friend with another 100 who maybe interested

I have already been talking with Mike about my order so I will ask about group buy. I was going to order his HC model, but could go with the bolt-on for the sake of a group buy.
 
Just got an email reply from Mike this morning. His is fine with another group buy. We need 5 guys to order the same bumper. Delivery would be late July/early
August. I will give it a few days to see what kind of interest there is.
 
Klaus,
Just to clarify, that is not a BIOR fuel carrier in the pictures?

Yes it is a BIOR Powder coated satin black to match everything else.

The gas struts are great. 99% of the time, they make opening the swing outs almost automatic. There were a few times when we were parked severely off camber where they didn't hold the swing outs open. Make sure you use the correct on on the correct side. Otherwise you'll have a really hard to close gas can carrier.

The stuts pop on and off with two little clips. So between the struts, popping off the dust cap and undoing one big castle nut, you can remove the swing outs in a minute or two.

Mike's welds are much better than they look on his website. I think the bumpers on his website are techinically prototypes.

Sorry it's a bit dirty:

Semi-capped wheel wells. They add strength and look a little more finished but make installation trickier. Cleaning hasn't been a problem. There's still plenty of room for a pressure washer. What is dumb, is that the bumper is about a 1/2" too short. If it really deflected here, it'd hit the pinch weld. Didn't have any issues with it in moab though.

These latches are great. Better than the ones Slee uses. They feature a catch for an extra layer of insurance. Even if the latch somehow rattled loose. The catch would stop it from opening. As would the spring pin.

Half inch steel recovery points. Trailer hitch with gussetting and chain anchors. His welds are much better than the ones on his website.

Spare spindle cover. This thing is solid. It's the actual spindle sleeve the arms are welded to. Features a grease zerk. Also notice the welded stopper on the bumper. That, combined with the gas strut, stop the swing outs from opening too far.

Mike is right. Satin powdercoating scratches much more easily. But it also looks way better IMHO, touches up easily with Rustoleum Satin paint and matched all the other accessories on your truck.

Upgraded adjustable tire carrier. The tire carrying part of this can be removed completely if you wanted to run the spare in the oem location and use the swing out for rotopax or something else since it's pre slotted for bolts.

I had him add an antenna mount for a light. But it's not real usable as an antenna mount because the hi-lift is right above it. The adjustable tire carrier is tighter to the liftgate.

For those wanting the tire to not block their visibility, you can mount the tire super low. Even at its height position it's still lower than Slee's spare tire and doesn't block as much visibility. That being said, the BIOR adjustable tire carrier need to be slightly taller. The lower mounting holes would be way too low with anything but a tiny tire. The way it's mounted now, it could move up one slot or down six slots.

You can see the license plate light bracket and strut here. I haven't installed the supplied light yet. The strut is great. It is strong enough to open itself.

The Hi-lift base mount was upgraded so it doesn't jiggle around. Or whatever the problem with the old one was.

You can also see the stopper tabs on the spindle. Just like the latch redundancy, the welded stoppers, strut and the bumper itself all prevent the swing outs from ever swinging into the body of the truck.

The license plate attaches with self tapping screws into predrilled holes. Instead, I tapped the holes to 1/4-20 and used stainless steel bolts with stainless steel washers between the plate and bumper.

You can see the adjustable backspacing on the tire carrier here. It used three grade-8 bolts. The design seems pretty strong.

There is a lip behind the tailgate with a notch for the oem spare tire pulley tool.

The trailer hitch sticks out farther than the Slee bumper because the entire bumper is a few inches shorter than the Slee. That's also why the bottom edge isn't angled like the Slee. The BIOR is flush up against the rear crossmember for the smallest overhang possible without cutting off the rear crossmember.

The swing outs slide onto that plastic striker plate when closed. The spring-loaded pins secure into the two 3/8" holes on either side of the striker plate. So to open the bumper, I pull in the safety latch, undo the large red handle, then pull up on the spring-loaded pin.

If you have to street park like me, you might want to have the spare tire on the driverside instead.

Updated with more detailed pictures.

The bumper saved the rear of the truck yesterday. I backed into a low concrete pillar in a tight parking lot going a couple mph. It hurt my hand against the steering wheel and the pole more than it hurt the bumper. The pole cracked and crumbled where I hit it. The bumper only suffered a red paint mark.
 
awesome details Klaus, thankyou! Definitely interested in buying one, GB or otherwise. How is visibility out the back with the tire on the passenger side?
 
No problems with visibility.

This is a 33 on the non adjustable carrier.

Description and photos of my bumper.
  • Bolt-on rear bumper, with rear receiver hitch.
  • Driver’s side - spare tire carrier, with standard high-lift & cb antenna mount, upgraded spindle. I like having the spare tire on the driver's side, your visibility is better. Your blind spot is the rear passenger corner, also when backing up you look over your right shoulder.
  • Passenger side - 2nd swing-out (with up graded spindle).
  • Bolt on dual gas can carrier (Scepter plastic gas) + (add cb/ mount to jerry can holder like the one on the tire carrier) and add another additional cb / flag mount welded to arm. I sold the dual can carrier to Klaus but kept the arm.
  • 4x4 Labs triple gas can carrier with a Tuffy Security Box mounted below. This was made for my 80 but it fit perfect on Mike's bumper, only had to drill one hole. In hindsight I should have had it welded on higher for better clearance. However with the cans installed the lower position helps visibility.
  • Uncapped ends but I made some plastic covers that work and look great. (Great idea I saw on here)

Can't tell if the tire or the 4x4 Labs can carrier will hit first?

Steel Core lockable straps keep my gas cans from walking away.

Perfect setup in my mind! Was it a hassle getting the carriers switched? I wonder if Mike would do the group buy with one set of carriers switched like you have...

Nicely done!
 
Not an issue at all, Mike took care of everything ;). This bumper was part of the group buy. The only thing Mike cares about with the group buy is that they are the same type of bumper (high clearance vs. bolt-on). Other then that you can customize the bumper configuration however you want.
