Adding height to rear suspension

Out of curiosity, is there a way (or product available) that will allow me to add 1-2 inches of ride height in the back? I'm wondering this because I was poking around underneath yesterday, and noticed that my half-shafts are angled up ever so slightly. I don't think it has a positive or negative effect either way, but to me that says there's unused suspension travel available. IF this is true, then perhaps the rear can be lifted to accommodate a fatter tire, like 275 or 285?

You can hit 275s on stock 17s by just rolling your rear fender. Also I belive drag bags are a cheap solution that *may* help raise right hight a little, at the least stiffen the rear helping reduce some of that loved wheel hop and give you more room for wider tires.

Do drag bags work like air shocks?

Drag bags will lift the car a little plus stiffen the rear spring rate. Give me a call here at the office.

Thanks,

I have drag bags under my car. It stiffens up the suspension and you can add or subtract air to adjust height and stiffness. Or you can buy some springs that will raise the rear end up some. Most GTO's I see with stock suspension have spring sag.

I`ve had drag bags in the `65 for over a decade. They work awesome.

Do drag bags alter ride comfort at all. My suspension still seems to be fine with 14,000 mile on the clock but I would like to stiffen up the rear a little. Would Drag bags be better then after market shocks.

The drag bags will help stiffen up the rear. They might make it ride a little stiffer than no bags but that will depend on the amount of air that you put in them. I also have koni adjustable shocks available that will allow you to tailor your shocks to your needs. Here is a link to our page if you would like to take a look. If you have any questions please let me know.
