air shocks....to do or not to do

RustyRatRod said

Any type of shock other than a standard, heavy duty hydraulic shock (NOT gas charged) will impede the correct operation of the rear suspension. Air shocks will all but stop the rear axle planting the tires. So, if you want a lot of tire spin, put air shocks on it. Regardless of whether you have 50 PSI or 150 PSI in them, they will still stop the rear suspension from working correctly.

I'd like to see the analysis that supports that. I doubt it is true. The use of air shocks increases the arch of the rear springs, more or less the same as would result from a weight reduction in the rear of the car. That doesn't mean the MOPAR rear suspension is impeded. The starting point may be somewhat different, but the spring rate remains roughly constant.

I drag raced my '65 Barracuda (last time 10 years ago) with 002/003 SS springs, Gabriel air shocks, shock extensions and ran a 60' of 1.46, 10.80 ET, 127 mph with a 4-speed car. I don't see where air shocks subtracted from any of those numbers.
