Air bag strategies

Pump them up before applying the load. That's what the instructions for mine (polyairs) recommened.

Hi alan,
The idea is to measure the height of the vehicle at some known point at the back, then pump the bags to 30 psi. Load the vehicle then drop the pressure till the vehicle is back to the original height.
Hope this helps, Cheers.

Instructions for polyairs -red and firestone coilrites -blue are similar , have vehicle unloaded and on a level surface , take note of distance of top of rear guards in relation to tire [ gap ] pump up bags , red polyairs upto 30 psi , blue coilrites upto 100psi , load vehicle / hitch up trailer ,, release air from bags until vehicle is back to level ,,

I think the reason the instructions say to pump up first and then load and then let the air out is to make it easier on your pump. If you have a decent pump it should not matter.

I load a slide on camper and find it easier to let all the air out - back under the camper and then pump it up to pick up the load. The reverse when unloading - put the legs down and then let the air out so the tray drops a few inches so I can easily drive out.
