Awesome picture of the quick jack in use. I don't think I've ever seen another.

Shelby strongly recommended against using the quick jacks. Basically the jacks are attached with all thread. I am sure any of the quick jacks used on todays cobra's would have to be strongly reinforced.

As mentioned by Morgan very few of the cars have the subsructure or actual framework to be able to support the weight of the car from the Quickjacks. They are for the most part "Ornamental", sort of like Earings on a pig.

You see them all the time at drag races in the pits and most are home made but this one is only $1,800

On SPF's they are not functional. Not sure about the other makes.

I would think that they would probably move enough to crack the fiber glass. I tried to reinforce mine when I built the car but I have never put them to the test.

I tried using mine on a Backdraft and was afraid the body would crack - they flexed like crazy as soon as the jack started up.

With a keen eye, it can be seen on the FIA cars the area around the lateral quickjack supports that protrude through the body is relieved (cut away) to allow for potential movement under load while lifting. Evidently Shelby & crew were aware that there was flexing of the tubular substructure.

They do not work on ANY Cobra, they really didn't work on the 60's cars either. The jacks and the bodies would bend under the stress.

I would agree that the body would crack or the extentions would bend at the weight of the car on the jacks.
Have you tried these?

I have never even thought about using a quick jack and my C3 Corvette frame has the complete bumpers attached plus my car weighs in at 1,000lbs more than most Cobras. As I said you can see these quick jacks used in the pits of most drag cars but they are used on very light weight cars. If you where building your Cobra yourself and wanted to use a quick jack and made sure the jacks were secured to the frame by welding or using adequate sized bolts, I’m sure it would be an easy install for your build.

The other detail that most don't notice is that the quick jack orientation on the car is actually BACKWARDS (i.e. the BIG tang is toward the back or the body side of the car). I first noticed this in a Cobra book my wife bought for me last Christmas. Makes since given the fact that you wanted an easy 'guide' of sorts to engage the lever.
Or said another way, all of the current reproduction Cobras have the quickjacks facing the wrong direction.

fsstnotch,
That is such a great photo! The dirt surface, hammer laying around, check out the guy on gas and the hose! And the driver out of the car behind the "wall." The guy with a bandana in his back pocket. How cool. The guy working on the tire looks like he's injecting something into a hole in the tire or something. So different than today's pit stops.

I think the quickjacks had to be "backwards" on the cars with oil cooler scoops. So just because they are "backwards" does not make them "wrong".

Mine work!
I've used mine several times without issue.
I have a long steel 'digging' bar. It's about 3/4" diamater. I put it on my floor jack and center it between the quick jacks. Lifts the car with 2 pumps.

I'd always heard that the quickjacks were nonfuctional, but I've seen the late Mac Archer's Cobra elevated that way on more than one occasion at Monterey. Didn't seem to do any harm.

When you get the Kirkhams to rebody your cobra, you might not want to do that anymore. I'm pretty sure the Kirkhams have strongly discouraged using quick jacks on clubcobra or their website.

My point was strictly 'functional'. I just find it ironic that all of the old Cobra pics show the quickjacks oriented exactly the opposite that you see ALL of the manufacturers today build them (even Shelby!). Someone must have decided at one point that the 'big end out' either looked better or, maybe, it was proven after the fact to be more functional!

Or facing them backwards from the early 289 car orientation proved functional in that you did not crush your oil cooler scoop when you jacked up the car?
