d-rings

how thick of metal should i use to mout d-rins to

[aemsee]

The d-ring hitch insert I had on my ZJ was about 1/2 inch thick. You will be concentrating a huge amount of force on to a very small area. Last thing you want is to have a d-ring flying at someone at a high rate of speed!

mine ar 3/8" and I feel that they are too small.

I'd much rather have 1/2 or even 7/8"

What I've got are more than strong enough to take a straight pull, but they bend if pull sideways.

Make sure you find a good way to mount them to the frame. Are these front or rear?

i wouldent just weld a mount to the front of the bumper. if you have a boxed bumper run it through the back side. bigdaddy offroad sells some nice mounts http://bigdaddyoffroad.biz/xcart/produc ... 255&page=1

When I did the front bumper for a buddy, we did a couple different techniques to ensure it was strong. This was on a square tube bumper.

- We welded it on the front of the bumper

-We also welded it on the back of the bumper

- And while I was at work drilling out the 1" hole through the 1" thick stock, I also milled a 1/2" x 1" square hole towards the end of the stock. This meant, that when the stock was slide into the bumper and welded, the square hole was flush with the back of the bumper. I then slide in a piece of 1/2" x1" bar that was about 3" long through the hole and welded that to the back of the bumper as well.

 

So this meant that all the force was not being directly applied to the welds around the hole, but also 1" on either side through the flat bar welded to the back of the bumper.

 

He did some major pulls on the those d-rings and not ths lightest bit of defflection after a number of years.

the way i was gonna do it is run it from the frame thru the bumper

That is also a good way... Say if you do 1/4" plate steel as far back along the frame as possible and grab as many bolts as you can. They you can weld the d-ring hitch to the side of the plate and the back of the bumper, and the front of the bumper and you'll be very strong..

 

My current plan for my front bumper, is to use 2-1/2" squre hitch stock in the same was as I described above on both frame horns. Then I will have the option of sliding in a D-ring hitch receiver, on either side, or slide in my front tow-bar. Just in case it needs to be towed somewhere... I wouldalso haev the option of using my ball hitch to make it easier for parking my trailer and what not...

if this is for the rear then that's the easiest way.

Mine run back into the stock mounts that have been cut.

A total of 4 1/2" bolts hold the bracket to the frame, and then the bumper bolts to those using another 4 1/2" bolts.

That makes for 8 bolts into the rear frame rails. All my crappy weld on the bumper has to hold is the weight of the channel, all recovery forces go straight to the frame.

Jeff,

 

Post up some pics of the weld on d riongs yoiu have on my old bumper. I welded the rings on the opposite side of where it mounts to the frame, and basically a whole lot of stiff would have to fail for the d-ring to break

I can get better pics if you need. These are just a couple ones I have handy right now....

That bumper is sweet! Plain and simple, yet sturdy. 8)

IT had rock rails down the side when I first built it for my rig :D and they stood up to some really hard hits :driving: and it is flush with the rear of the rig. The only thing I wish I would have done differently is the way I mounted the reciever. But...its not mine anymore ;)

Hey pong, where you at? Just curious. 8)

[GirsMJ86]

Jeff, can i get some better pics and info on that bumper? might look into moding the 91 i am going to be getting here soon that needs a rear bumper and i really like how clean and simple that looks. thanks alot.

I am an hour South of Richmond VA.

 

 

The bumper was built using the stock bumper mounts, just slightly moddified :teehee: Between the frame mounts is a piece of 4x4x3/16 angle for added stiffness. then it is all welded to 2x4x1/4 "C" channel. Down the sides there was 2x4x1/4 tubing, but Jeff decided he didn't want to cut his rig up that much to mount it like that, so he had me cut that part off when he came to pick it up.

 

It was designed to sit flush with the tailgate.

I just pulled my back bumper the other day, but I made sure I saved my brackets. :D 8)
