Is anybody actually using these and had any luck with them? Seems simple enough but I kind of question how long they would last before they would let go. But I do like that they would isolate the vibrations from the frame a little. http://www.speedwaymotors.com/Universal-Expanding-Body-Mounts,27868.html
I used them once, when total performance was makig them, THEY SUCK. I hit a really hard bump in the road, and the body lifted from the frame pulling those out, but since they were "compressed" when it came back down, they wouldnt go back in the holes till I could get home and decompress them (and then remove them and do it right). As for a timeframe, they were about a year old. They would have done it at any time though when I hit that bump.
Basically just a well nut. Have seen 2 out of 4 fail on a T bucket after a few years. Works great for license plates.
...until you try to remove the plate and they spin around! LoL I wouldn't dream of using those things. Use a bodymount design that, even WITHOUT the rubber part, still won't pull thru the hole. Thats the only safe way and there are many variations on that design that you can use.
When I first built my T, I ordered a set. Upon arrival, they were quickly tossed. I was TOO pissed to even return them. The more I looked at them, the more I could see the body of my T flying off the frame. They may be good for something, but holding a car body to a frame, isn't one of them. Look at the pic and read my last line. Scary? YES!
Harley has used Well Nuts on many lightweight body parts for years ~ and they work fine for that. But I would Never use one that require larger than about A 5/16" BOLT ~ And I sure hope your body mounts are larger than that.
got some of these from Total Performance. Pulled right out during the install. Wound up welding outriggers on the chassis and using conventional nuts, bolts, and rubbers. wouldn't suggest using 'em.
Go with it. When I use to use rubber isolators I used a bolt that had enough threads to allow for a large washer and lock nut on the under side so that they could not pull through. Make sure that they are long enough to create a good swell diameter on the under side.
I've used them before with similar results to what others have commented. If you save a few minutes by using them, you may spend a lot of time if you ever have to remove them; which is not an option that I want to deal with again.
Alot of Jeep guys have been using hockey pucks for many years. They beat 'em up pretty good, twist the bodies all to hell, banging 'em off rocks and trees, etc. Big Super Swamper tires put out alot of vibration and the wide dimensions of the pucks seem to isolate alot of that while not getting all gushy. Of course they have bolts all the way through.
Well looks like the general consciences goes right along with my gut feeling. Would be handy if they were effective but.....
That's what I did with my T Bucket and the body stayed with the frame after my wreck. Total Performance had some great ideas for T Buckets. Those mounts were NOT one of them.
