    Making front and rear bumpers, wanted to see what yall's take on it was. I've got a choice in material between 2x4x3/16 or 2x4x11ga. 11 ga is .120 material. Do I really need the extra thickness of the 3/16? All I'm running on the bumpers is a reciever hitch thru, and 2 d rings front and rear. The 11 ga gives me 15 pounds of weight savings over 3/16 per bumper but I want to know if my strength is up to par. Thanks gurus.

    I would go with the 3/16, especially with D rings used for pulling/jerking, and depending on how heavy your rig is, even for jacking on, or the occasional tree encounters.....just my 2 cents...ED

    I'd go with 3/16". It'll survive much better.

    If it weren't for bad luck, I'd have no luck at all[​IMG]

    dang it, that's not the answer I wanted..lol. here's the weights of each
    3/16 bumper at 78" (approxamation) 44.7 lbs
    11 ga bumper at 78" 29.6 lbs

    That's a lot of difference. I really want to save weight, but dont want a bumper that's too light duty. Normally I go with overkill in my projects and my shop does too. Nice bulletproof products, but you've got to know when your strength is where you want it to be. I may go ahead and make them out of 11 ga and then reinforce the reciever and d rings back to the frame. Any other insight?

    And mike, i was going to use schedule 80 water pipe with some neat balsa wood winch mounts, but balsa wood is so expensive! sorry about your yahoo experience. I use IE and have had no problems. I'll see what I can do about going icq. Later.

    Bryan, my bumpers are 2"x8 1/2" ( I know its an odd size...) box tubing...0.125" wall. I ran some plates from the frame through the bumper for my clevis shackles. That way i am pulling on the frame instead of the face of the tubing. As for being strong enough? Well the rear took a direct hit from a full size Ford and only bent in about 1 1/2" at the outside. The body behind the bumper isn't even dented. BTW that 4000 lb Ford was doing 50 MPH when she hit me.
    The rear face of the bumper tubing did not deform or dent either, it just has a gentle curve to it now.


    Box tubing is very strong...normally i like overkill, but I think 1/8" material is plenty.

    that's probably what I'll do rene. I just hate pouring the weight in since blazers are heavy enough as is. It's nice to see someone else with a similar setup doing well. I'll probably run the attachments for the d rings and a brace for the reciever from the frame, then use the tubing for the main bumper. My tire, jerry cans, ect are in the bed so total support is not needed. Plus the 11 ga tubing is FREE!!!

    Does anyone make decent pre-made custom bumpers for our trucks?

    yeah SEC is the leader I think. I hear a lot of raves about them and they do killer work. But they're sooo expensive. There's a price list up somewhere. I've got access to a welder and chop saw so I build all my own stuff wherever I can!!! Plus there's the personal pride of having made your own equipment! But to answer your original question, yes there are places. SEC is good, steer clear of KMA. And bring a full wallet!

    i dont know yet fizzle...but probably full width for protection, also putting a pick front and rear out of 1-3/4" .120 wall and it would be nice to do it all the way across.

    Just stay in touch mike, I'll probably have some pics up tommorrow or the next day. So stoked about finally getting this project on the road!!

    I'd go with the 3/16 because besides the other reasons given if some one runs into ya you won't have much damage.

    Go with the heavier of the two. You will thank yourslef for it later on when you go use on of your d-rings and it does not decide to pull through your bumper. It is worth the extra weight. Just my opinion.
