Simple Bumpers

[Rockford514]

I needed some bumpers and a place to stand
Rear I started with 2x8x3/16" tubing

added 2x3x3/16" side nerfs

45ed the ends

Wanted a skid plate to feel the gap

and ready for paint

 

[Rockford514]

Front bumper pretty much the same

Used the peaces I cut off the feel the inside gap

 

[Rockford514]

front pull point is coming off.I was low on acetylene will be building new pull points front and rear

 

[cowboy73]

Looks good. Can't wait to see it all finished and painted up.

 

[tonydanzah]

the look like they weigh a little bit! Did you remove the piece of accordian frame rail from the front when you put those on.

 

[Rockford514]

"accordion frame rail " 87 doesn't have it,I think that started in 92.
rear 150.5lbs
My buds Fab Four rear bumper weighs 189

 

[jam022316]

Great job. I'm assuming by the lift that you don't have very strict lift laws!

 

[Rockford514]

Off road only,where all Big trucks should be.
specs:25-28" lift,514,C-6-205,T-136(2.5 ton transfer case) 2.5 axles welded rear.
Tires are 53" will have a 55-60' tractor tires soon

That's pretty damn cool. I'm not even a 4wd guy, but that's an awesome truck. Any action shots, or is it still under construction?

 

[Rockford514]

Still under construction,been playing with this

 

[jam022316]

That's badass man! Love both of em!! Probably takes a step ladder to get into!

 

[akdiesel]

Nice work.
You don't need a lift to change oil when you have a truck you can walk under on own wheels. Christ that thing is tall.

 

[shotgunfatcat]

And I thought I had a big truck, those rockwell's?. Nice job on the bumpers.

 

[Rockford514]

Yep 2 1/2 ton Rockwells 6.72 gear

 

[Rockford514]

Front pull point

And I got my new tires 18.4x26=57" on 20x26 wheels

 

[blue dog]

What does a truck like that way in the finished state? those rockwell axles alone are heavy sob's. Build burly if your gonna drive like you stole it, and 'm sure you are.

 

[Rockford514]

7,500 ish It was 6,060 on 1 tons and 44s
Hope to been finished by next weekend

 

[blue dog]

I actually thought it would weigh more, those axle gotta weigh a grand a pop, those wheels and tires what 350 per. What is the power plant and trans in your obsession.

 

[Rockford514]

514 BBF C-6,205,2 1/2 case,1550 U-joints,around 25-28" of lift
Front axle
Rockwell w/o drums = 682
rockwell w/ drums = 842lbs
Rear axle
Rockwell w/o drums = 532
rockwell stock = 692

 

[mcgyverit]

great looking rig! thanks for some of the ideas

 

[Rockford514]

Checking clearance and tearing down in the AM for final welding ,sand blast and paint.Should have her back together by next weekend

 

[Rockford514]

Built another little bumper,72.5lbs.

 

[Rockford514]

Finished the rear bumper,heading back to the painter

 

[e-tek]

GREAT PICS, great SKILLS!!

OK, school me: is there any advantage to big-weight? As said, the axles alone weigh tonnes, so why add so much more with the bumpers? I would think one could build something near as strong with lighter material - No?

And what is the disc brake set up on the axle for?

Again - thanks for the pics - I love learning and seeing great skills at work!

 

[Rockford514]

Bumpers on the Full size are around 150lbs. each and are more for standing on than anything else. At some point there will be mud + water up to them and hooking up for a tow would SUX with nothing to stand on.

50+inches of water-mud

Disc on the axle"pinion brake" are the only brakes there are for the truck
Front

Rear

 

[Rockford514]

On the pinion brake set up.I put this together for the blue truck
1987 maxda B2200 2wd front rotor,87 toyota 4Runner 4x4 front calipers

I used an old chunk for mock up

4" hole saw and 1/2" plate

 

[blue dog]

I would love to come hang out in your shop for a day. My passion is desert race rigs but i know there is stuff to be learned from what you guys do.
When i look at rock crawlers i see serious parts that are bulletproof, my only issue is the weight for my application.
What kind of gear ratio is in those rockwell's and i would be curious to know what kind of travel you get out of that bronco from full bump to full drop. And i know you guys are not going for travel, i am just curious.

 

[Rockford514]

2 1/2 ton Rocks 6.72
5 ton Rock most 6.44 some 8.**,10.26

 

[Rockford514]

My buds mud truck

 

[Rockford514]

Some Old mock up pics.No springs but

 

[metal1313]

thats a pretty impressive amount of flex for a huge mud truck. still makes me wish i could keep my bronco

 

[ForceFed70]

My buds mud truck

Very impressive flex for a bogger!

 

[blue dog]

Do these machines drive much better [ more comfortable ] with coil overs as opposed to leafs front and rear?
is the single brake on the rockwells enough stopping power?

world of difference between our rigs.

 

[Rockford514]

Leafs work but after a place get cross rutted ,they will KILL you.

1 brake seams to work for a lot of guys.I have always ran 2.
At events the roads to the holes are FULL of damn 4wheelers,most are drunk and think you can see them.

The blue truck will stop ALL 4 tires at any speed we run,and I mean STOP
the brakes have a 6.72 advantage over wheel brakes

 

[Rockford514]

"world of difference between our rigs."
Never seen desert trucks run in person but LOVE some whoops vids

 

[blue dog]

Takes some experience to get used to rolling threw big whoops while traveling fast. Whoops are like marriage, you are 100 percent committed when you enter them, and you have to be consistent or you are going to wad up your truck.
Back to the your brakes, don't they get all packed with mud doing what you do? I have never sloshed around in the mud in a monster like you have there, i could only imagine it is like being a kid again.

 

[Rockford514]

Blue truck when it had the OLD 2 1/2 ton GM face loads

63" tires in there somewhere

 

[blue dog]

mud mud mud, looks like fun.
are those trucks hard on the bearings with those monster tires?

 

[Rockford514]

The bearings are huge.Most guys drill+tap the hubs for zerk fittings and keep them pumped full.On 2 1/2 ton rock all 4 hubs are packed with grease,there's a outer seal on the rear to keep the gear oil out of the hub.

dana 44+2 1/2 ton

2 1/2+5 ton

 

[iagsxr]

Like those bumpers. I'd like to do something similar on the rear of my snowplow truck w/a couple clevis mounts. "Recovery points" I think they call them. LOL

I'd like to lift my plow truck 4"-6" max and gain some articulation(75 Chevy 3/4-ton). You guys know any good sites to look at components/builds? I've trolled around Pirate 4x4 a bit, but it's more ******** than what I'm after.
