    Anyone tried hot rivets replacing the front bumper on an early? Walcks has the rivets and bucking tool but can it be done correctly with an air chisel tool or will it require a hydraulic tool? Any experience would be much appreciated. 2nd option would be the bolt on break away rivets
    Thanks in advance!!!

    I just bought a front bumper from them last night and saw the rivets and tool.

    Looks like it would work if you had a decent chisel and got the rivet glowing hot.

    I'm just gonna bolt mine on with G8 hardware.

    Seems like some of the guys on the G503 did the hot riviting on the rear frame rear cross member.
    Quote from G503: I was able to get some HUCK BOM Rivets for my jeep.


    Seems there is a rivet that can be installed with a bigger rivet gun air/ hyd.

    Huck BOM Rivet

    They have the rivets.
    Huck Tools has rivets and rivet guns:
    Huck Rivet Gun, Huck Riveter, air gun, rivet gun, Huck 940 Powerig, Huck 2025 rivet gun, huck 256, rivet tool, huck tool, huck bobtail, huck Hydraulic and huck pneumatic tools at www.huck-tools.com

    Some research should turn up something that can work.

    The bolts today are better than rivets, so unless you are after original grade 8 bolts are stronger. They quit using rivets when high grade bolts came on the sean. The cool thing about rivets was that you drove them hot, and as they cooled the shrank and got tighter, filled the hole completely. Just saying. Good luck.

    I did the hot rivets many years ago on a rear crossmember. I heated them red-hot with an oxy-acetylene torch, stuck them in with a big pliers, bucked them with a mini anvil (short piece of RR rail), and used an air chiesel with a big flat head. It took about 30 seconds each. Super tight great results.
    I'll do it again on an upcoming project.

    Those would have not been installed Hot.......I'm a huge fan of Huck products and use them all the time , but I would not have used the Huck pull rivet for anything that is structural like a cross member or frame...........On the other hand the Huck Bolt is an excellent product ......which is a grade 8 hardened bolt that comes in various head designs , sizes & lengths.....and has a unique thread like shank that uses a hardened collar that is swaged on with an air over hydraulic gun..........

    They are so good that you hardly ever see nuts and bolts on HD truck chassis or suspensions anymore and for that matter even in heavy duty off road equipment as they just do not come loose.........the only downside is if you have to change a broken part or suspension bracket you need to pull out the cutting torch or cut-off wheel and cut off the swaged collar and then drive the shank and head back through the chassis.........at that point you can use a grade 8 5/8" bolt to replace the brackets or purchase a $2000 gun to reinstall new Hucks....for a while we replaced the brackets with bolts and found that they would no longer stay tight in high stress areas so I bought the gun.........

    Looks like this ...............depending on grip length the end breaks off at predetermined weak spot so only a few threads are exposed beyond the collar....
