Question about raisng rear end

Hey guys I am looking to raise the rear end of my 1980 camaro a bit. I have found these adjustable shackles and I believe these are what I need to use to do this. attached is the 2 models of the shackles, only difference between the 2 is one of them uses 1/2" holes and the other uses 7/16" holes. Could anyone tell me if this is what I should be using and which one of the two would I need for a 1980 camaro.

Shackles are a bad idea and IMHO look dumb. The proper way to raise a car is to either re-arch the springs or install air bags or shocks. Shackles screw up the geometry of the spring.

Yes re arching springs is a good idea and so is the air shocks as previously suggested. I have used air shocks before alot of people say no dont use air shocks they are not safe. I used them and was ok. The ride is rough at first if pumped up all the way. How ever I kept them pumped up all the way as best I could between leaks. And after maybe a year or so not real sure on the time it was long ago. The springs had re arched themselves. So at that point if you were really unhappy with the air shocks you could put regular shocks back in and your springs will have the desired arch.

This is not ideal but it is cheap and easy way to go about it.

Long shackles will make you look like a hick. Get the springs re-arched.

Not only are shackles going to make folks think poorly of your suspension modification, they make the rear of the car shift sideways in corners alot more..those shackles flex like crazy ...

I have heard that re arching the springs sometimes can not last if done wrong, even many new repro springs are not as good as the OEM stuff...Seems like alot the springs I've ordered and installed on folks cars has made in China painted on them...

I had air shocks on my car and pickup for many years with no problems. Cheap ones are not as dependable as the higher priced stuff, the set I have on my pickup are at least 15 years old and still will take 200 psi ...The ride is ok at lower pressures and you can adjust the height..I also had a set of the cheesy springs that slip over your shocks and are held in place vertically with big clamps, they are out of view and give a boost to the rear leafs to get the back end up where it belongs. You can adjust the height some with those, but the clamps slip off and chew up your shock. .....They also sell shocks with the springs already installed, those are not adjustable.. Monroe Load Levelers

Here is their listing for a 1980 camaro..

Much less money than new springs and your car won't look hokey..

You can also get a set of air over leaf airbags, those are not a bad way to go either but take some time to install and take up extra room...

Later, mikey

the rear of my s-10 2wd pickup has shackle extensions and all they are is a pair of flat narrow pieces of steel with many holes in them and it allows the main leaf eyehole and eye bolt to be way below where the factory eyebolt hole in the shackle is

the rear most ones on the truck

working fine but gemotry of the shackle itself is screwed because it is nearly hitting the underside of the lower of the frame rail

but i drive it daily anyways

no problems


previous owner did it


the right way is definitely arched or more springs, or put the axle under the leaf packs, unlike factory axle being on top of the packs at least on the s-10 trucks anyways

which is really just the combination of an '80's G-body front chassis with a second gen camaro(or whatever else was leaf rear)leaf rear setup,

for the most part

haha

good luck
