    I think what he meant was that a jetboat is direct drive where as cars generally are not.

    what he said. steel straps are fine. remember not to over tighten or you can distort the hosing the needle bearings ride in.

    Just depends what kind of use, the fatigue factor for aluminum is huge compared to steel, but Aluminum is very strong, rigid and lightweight. One reason for running aluminum rods in drag race motors. Not good for a lake cruiser, but awesome for drag motors that tear down frequently.

    I would think in this application the benefit of weight versus fatigue life, I would use steel and forget about it.

    I would say that from my experiance they are about as strong as your normal steel straps just add to the bling factor. There only job is to hold the u joint against the yoke and do not take the full load of your drive line.

    A little digging finds it is 7075-T6 alloy.

    I'm sure they are an aluminum alloy.

    I dont know how i feel about them. I've had a pretty hardcore jeep that saw a ton of abuse and i'm fairly impressed with how well your standard ubolts have held up. The fitments have to be very close in the ubolts to have them hold under the extreme conditions, i just worry about those, esp as they wear and start to lose their true.

    Are they brass or aluminum.

    Have used them in the dune jeeps for a long time, never have had any problems.
