Bumper Mount Strength??

Hi All,
I am getting ready to mount the rear bumper on my jeep. Here is a shot of the bumper and the mount. How strong is this going to be? I want to build in some clevis mounts and I am not sure how strong the original rear crossmember/bumper is going to be as this is what the new bumper is mounted directly to. Opinions?

Is there another bumper? I see brackets on the rear crossmember.

There was no real 'bumper' as such, just the rear crossmember and the drawbar. The drawbar is very sturdy - wouldn't want to bump into it while parking. The crossmember is fairly sturdy, but you can bend the ends over pretty easily on the trail by backing into something at more than a crawl.

Oh - never mind. I see a bumper the same shape as the rear crossmember now. Looks good!

 

The mounting brackets are welded to the cross member and the bumper bolts to that. I guess my real question is if I mount recovery points to that bumper will the cross member hold up in a recovery situation?

I even go one step further than that. I run my recovery points thru the bumper and then attach them to the frame. That way the bolts are in shear and chances of shearing that 3/4 inch bolt is pretty slim. I will pull the frame apart before my recovery point fails.

 

Like JeepTherapy said, tie into the frame if you want true recovery points. The crossmember is more for the tub mounts and tieing the frame together in the rear. I like the setup of JeepTherapy - way beefy and when you pull your really pulling on the frame. Most of your pulls will not be dead on a 90 degree to the bumper.

Weld the d ring attachment points thru the bumper then bolt the bumper to the crossmember on both sides of the frame. Use the "L" brackets like Boyink did. Line the attachments points up with the frame ends as this is the strongest point.

 

That, by god, is a BUMPER!

 

Very Nice!!!!

Did you do away with the rear crossmember with this set up?

I desire to build a rear bumper/tire carrier soon. I will take a good look at your design.

My cross member was shot. So... if you look close in the pic you will see that I actually replaced the cross member with a piece of 3X3 angle. The receiver goes thru the bumper and is welded to the 3X3 angle. Front bumper/winch mount is built very similar. What you can't tell from the pictures is the way I sandwich the frame. The recovery points are actually three pieces. 1 piece on the outside of the frame, one on the inside of the frame and then a filler to make up for the thickness of the frame. I did the back a little different but just as strong. The 3X3 angle is bolted in place with 3/8 grade 8 bolts in the cross member rivets holes. Then I have 3X3 along the edges of the frame and a then a 1/2 inch piece.
