Quick Jacks

[Mike.Bray]

This is just a curiosity, I have no intention of trying it. I understand what the quick jack brackets were originally designed and used for, are the ones on a FFR car actually strong enough to use as a lifting point with a jack or by the Terminator? Has anyone ever tried it?

They are just steel bolts. They would bend and break. 100% decorative.

They’re there for looks alone.

Has any one done a mod to make them real/functional?

[Mike.Bray]

With the Kliener mod the rear would have no hope. The fronts aren't "just bolts", they have sleeves and are secured to the frame well. Tie 4 of these together like you were lifting with both quickjacks and they're probably stronger than you think. I doubt strong enough though.

I might model it up and do a little FEA analysis to see what the capacity actually is.

If you modified the support structures both front and rear then built a .500" shaft, threaded on the ends it could work. Would need more than just nuts to hold the rods, probably a 2-3" cylinder as the bearing length rather than a flat plate. That way the rods (4) would hold the weight rather than the ends.

But... the original lifting frame was difficult to use as well. New lightweight jacks and good chassis lifting points are much easier and more compact.

I had quick jacks on previous cars. Polished stainless, substantial and attractive. They attracted my knees, shins and anything else that came close when working around or under the car. I still have marks.

That's funny!

Your comment is spot on. If one lifted one quick jack it would take all the weight. Two at a time splits the load. One jack person at a time is a challenge too. The height is fixed, tire removal or oil change height?
In a design sense one needs to project frame strength cantilevered out a distance from the frame. The bending moment is greater at the root of the jack structure.
