I do not have any leads or hookups on dual needle gauges. But 40 bucks shipped will be tough to find. As for you rear control arms I am assuming you are boxing them in correct?
So you are running this compressor.....
3/4HP DC5000 BARE 18AMP@0PSI
What vavles are you running? You said manifold style.... Like this.....
Are you going for fast bags?
And hot rod I will soon have a air ride only website up...... Air Ride info on products, installs, pictures, ect.... I do not sell air ride products or provide installation. The site is completely free and for air ride information only....
So spread the word.......
