The previous owner put air shocks on all 4 corners and they leak. The rims stick out a bit and the front wheels rub. I’d like to put some 60 series rubber on it. Not really wanting to put air shocks back on it.

I’d like to install a 1” coil spring booster up front . Does anybody know the spring diameter ? 1” is how much the air shock lifts the front. Refilling the shocks every morning is getting old
