Rear air shocks

I am running rear air shock on my 68 chevelle to get some height, I always felt the rear on those chevelle sat to low and easily bottoms out. Is there any down falls in have air shocks in the rear? Does it cause hopping on tight turns, do to the stiffness?

This is the problem with air shocks, the shock mounts weren't designed to hold the car up! So breakage is VERY common when running them. Get yourself new springs to solve the problem correctly.

I have to disagree with Brian on this one simply because I think it depends on the car. Back in the day (late 60's-early 70's) I ran air shocks on my 68 Torino, 69 Roadrunner, and even put them on my 74 Charger and never had a problem. That said, I never pumped them all the way up...just enough pressure to gain a couple inches and get the stance right.

Air shocks are more commonly know for inflicting damage to Unibody Cars, but certainly have been known to do some damage to the Framed ones as well. The absolute best way to correct a sagging rear is to get new springs. If you don't like the factory stance - the solution is the same, just bump up to wagon springs from a like model or some after-market springs made just for raising the rear.

With that said, air shocks have there place for an inexpensive fix and lend some adjust-ability. Just don't pump them up alot and drive like mad across the tracks.

As far as handling goes, if your concerned about losing control while aggressively taking corners, I have to ask if your car is set up with any suspension mods that would improve it's race-ability anyhow? Old muscles cars where not known for there cornering and air shocks will stiffen things up a little, but there are better solutions. A stiffer suspension could actually start sliding before one that rolls, but the timing, repeatability, and control of the slide will be more predictable.

I agree and disagree here. Air shocks were designed for vehicles that primarily towed things like a boat, trailer etc. With the additional weight load, you could add air to the shocks to level out the ride. I've never heard of anyone ruining a suspension due to breakage from air shocks. If you pump the shocks full then yes your going to get a rough ride and the bounce around corners. If you simply want to raise the rear a bit, air shocks will work fine. If your springs in the rear are bad, the wise way would be to replace the springs and just run normal shocks. The main problem with air shocks is the air lines. Keep them away from hot items like exhaust. You puncture the line and your Chevelle will be really sitting low!

From a street/strip perspective, airshocks are the worst thing you can do as far as helping traction. They are more air than shock, have poor damping ability and can increase wheel hop on launch to the point of breaking things from shake(suspension arms, bushings, axles, ringand pinion gears, driveshaft, trans case). They are pretty much the worst thing to use.

AirLift air bags inside the existing springs along with good shocks, or new springs and shocks would be a much better solution. New springs don't cost any more than airshocks, so might as well do it the right way.

If you want to do it "A-Number One Right" then do it like Brian says. Nothing beats a well tuned suspension including springs, shocks, bushings and sway bar. Station wagon springs for the same car would probably do the trick. If you go too high you may cause problems in your pinion shaft to drive shaft angel. It is a full frame car so air shocks are not that bad of an idea if you are on a budget and you don't plan on jacking the car up more than an inch or so. They are intended for use as an assist when a car is towing extra weight. But like it has already been stated they don't do that good of a job in the dampening department and if you put too much air in them it will make your car hop around. I like bags as a total replacement for the coil springs (true air ride) but don't confuse this type with the type that go inside the coil spring. I'm not fond of the type that go in the coil spring because I have seen the coil rub a hole in them.

I have ran them years ago but not anymore if you don't have alot of cash then i can understand someone running them unless they just like them that is. But if you do run them i hope your tires don't stick out to far. If it were me i would invest in some new springs thats the best thing to do as already stated .JMO
