First let me say, Damn this board is sweet!!!! I have been looking for a 67-72 forum forever. I have a '72 blazer and suburban both on Air Ride. The blazer is straight nascar, but it has a ways to go. I will try to get some pics of it on here soon.
On to my next topic. Those of you that have Air Ride will want to check out this site,
http://accuaircontrolsystems.com We have developed the coolest air ride control system ever. It gives you the ability to save any of your three favorite ride heights and re-obtain them at the touch of a button. We sensors that directly measures the height of the vehicle, NOT PRESSURE. So you can add weight to the truck, and the system will bring it to the correct height when you hit the button. We also offer a key-fob remote that triggers your three positions and the "all down" button from a distance. Unfortunately, the systems are expensive to build due to the quality, but we hope to be able to drop the price as our volume increases. One thing is for sure, once you use our system you will never go back to 4 rocker switches and guages.
If any of you are interested, let us know that you found us through this forum and we will give you a discount.
