Hey Folks, I need some input on typical airbag pressure needed for a 3800 lb car. I took advice about which parts to order from a guy who did airbags at his home shop. Big mistake. He recommended AIRBAGIT.com. (In retrospect I won't order anything from them in the future but that's another story.) Long story short, it seems to me it takes way too much air pressure to get the front of my 54 Chevy up to 3 inches of ground clearance without bottoming out on a hard dip. At that height I have to have 105-115 lbs of pressure in the bags and the ride is pretty stiff. I suspect the bags the guy recommended were for lighter mini-trucks since that was mainly what he dealt with. (18 mos later the part numbers I ordered are no longer listed on AIRBAGIT's web site so I can't verify specs.) What brands are you running on your 50's era ride and what pressure do you typically see at three inches of height? (Note: I am not interested in Shockwaves - just conventional double or triple convoluted bags.) I read a thread where Slam Specialties has good stuff but when I read their specs all they sell are for 1/2 inch lines. (Mine are 3/8 in.) I am not interested in bouncing my car I just want a comfortable ride at cruise speed. Talk to me.
