No telling what it would do, depending on what rpm it lets go.. If it is high rpm, I am sure it could still flop around enough to **** the tank and other things up. I did the rear one for piece of mind

I remember years ago when one of the techs at the Chevy dealer forgot to tighten the u-joint straps after reinstalling the rear driveline. It was on a company vehicle for a local construction company. The kid who picked it up was heading back towards Eagle River, and only got about 4-5 miles away from the dealership when the driveline ejected. We had it towed back, and found the driveline bent, muffler caved in, and transfer case tailhousing cracked. The gas tank had some really cool marks in it, scratches & gouges, but it was all superficial and the tank was still good.
What an expensive **** up that was....... The service manager was pissed!

just for insurance is nice but remember for track rules (if you slicks), I believe you need one no more than 8" from the output of the trans. The tracks don't care how much damage you make to the underside as long as you don't catapult.
I've been at some tracks when they consider drag radials as a loop requirement.
A driveshaft safety loop is required when you run slicks. With street tires or drag radials, no loop is required until 11.49 1/4-mile (7.35 1/8-mile) and faster.

Here is the loop I made up, so they would be similar to this.. IIRC there is 2 holes on each side of the frame rails that this is bolted to( been a little while since I been under the truck)
I also have one in the rear, but it is welded to the frame of the truck.. The fuel tank was a issue for me also...
let me know if your serious..

On mine I will take some pics because in the front I already had a bar going from one frame rail to the other so I would just need the loop and mounting legs.
And on the rear I also have a cross member but it is above the driveshaft so I would need a loop just like the front and just install it upside down with the legs up. That what she said, lol.
