"Convertible" Lift Shackles 1 1/2" to 2"?


I just came across this and haven't seen any like this before. Figure some people on here might be interested in it too because it's one shackle that has the ability to provide 2 different lifts. Many people here have the ability to make them their selves too.

"Bulletproof shackles"

Fits JEEP CJ-7 1976-1986

Convertable shackles

Why buy a 1 1/2 or a 2 inch set when you can have both ?

We have made or shackles so if you want a 1 1/2 inch lift now and get bigger tires later you simply move the bolts to the lower holes and now you have 2 inch lift shackles .

Its just that easy.

So you want 2 inch lift in the front and

1 1/2 lift in the rear....these are the shackles for you.

interesting to say the least.

first off, anything over an inch is too much.
deciding these "might come in handy" down the road, is just poor planning.

Really... This is the first time I've seen them for CJ7's. Is there a reason why anything over 1" lift with shackles is bad?

There is a general consensus that shackle lifts are not the proper way to add ride height. You can run a search on the forum and there are many discussions about why. However, it is a cheap way to get a little extra height to run some bigger tires, but it is not good on steering geometries and isn't really functional for off road use. I would compare it to a body lift... 1" has benefits but 2 or more causes weak points, stress points, and can get dangerous.

Whenever something breaks on my Cj... I learn something new by fixing it.

I was planning on a 1" but possibly 1 1/2". Would the 1 1/2" be bad? I mean I got 4" lift springs, so if I did the 1 1/2 that would net 5 1/2" of lift. I don't want to run a body lift, wanting to run 33's and then maybe 35's in the future. With Tube Fenders up front, possibly the new metalcloaks available. Would 5" of lift be enough for 35's in the future?

Or could it be possible to make instead of 1 1/2" to 2", make 3/8 to 1" lift shackles instead?

If you get the hd shackles, they are 1/2 longer. Then a 1' body lift and you are set. To get 1 1/2" lift from shackles you would need a shackle that is 3" longer than stock.

I don't like body lifts. But how about making a shackle like this but it being able to be a 3/8 or 1" lift.

Keep it under an inch and you're fine. Anything over that reduces the caster angle in the front axle to the point where wandering and the lack of return-to-center start to occur.

It's been posted many, many times here.

The other thing long shackles do is put extra leverage on the spring pack causing the springs to flatten out and stress. Additionally, over the long term, as the spring flattens out you lose whatever lift you originally gained.

Like one poster said, shackles in the 3/4" to 1" lift are probably the most you would want to go and not have problems.

for 1" lift the shackle needs to be 2" longer. Stock shackle is either 3 or 4"(cant remember but i'm leaning to 4" so a 2" lift shackle wold be 8" long. that's just STUPID!
you would never find a shackle more the 1" longer then stock on my jeep (1/2" lift)

ok you guys got me convinced. Thanks for the information. I wasn't aware of that. I'll probaby go with HD shackles either the 3/8" lift or max of 1" lift. 5" of lift should be plenty to run 33's anyways.

Determining the needed shackle length isn't magic. Shackles need to be long enough to allow the spring to flatten or else the long leaf will abruptly stop or bend. They also shouldn't be longer than they need to be.

Vibration? Bump steer? Wandering? Read the article (sticky) on Steering, suspension, and driveline.
