    Took the old girl for a spin today.

    Well overjoyed at the stability and increased ride height from using the air units.

    Running at 40psi at the moment which seems to give a very reasonable ride.

    What pressure do you run yours at?

    Wish I had some times too....:Doh:

    1 bar = 14.5037738 pounds per square inch. Good old Google.

    Mine are at 60psi which are Firestone Ride Rite, thats what the chappie before me had them at. The majic book suggests " 50lbs of load for each P.S.I. of inflation pressure per pair e.g. 50 p.s.i. will support a load of 2500lbs per pair of springs.FOR BEST RIDE use only enough air pressure in the helper spring to level the vehicle when viewed from the side. TO PREVENT POSSIBLE DAMAGE TO THE AIR SPRING MAINTAIN A MINIMUM OF 10PSI AT ALL TIMES and never go above 100psi"

    I'm staying at 40psi I think.

    Good balance between road ride and body roll...:thumb:

    Really depends on total vehicle weight,body height and personal preference it seems.

    have my ride rites at 45 psi might try a little more to level her out the handling improved greatly when i went from 25 to 45.

    Settled at 40psi for mine at the moment as it gives a nice balance between ride quality and body roll control.....

    I cannot believe the difference it's made...:Cool:

    I'd never checked ours :Blush: but did recently and found out exactly why Winne wandered a bit, near side approx 15psi, offside BURST! Some idiot had replaced the offside but not fitted the top and bottom protectors so supprise supprise the top of the spring had put a hole in it:Angry:

    Any road, replaced and currently running 55PSI (60 seemed a tad hard when driving)and what a difference, sooooo much nicer to drive. I got keen and got the remote inflation pipes off Duncan at Newark, can't be doing with all that crawling around, and will now be checking regular, book says once a month at least but I guess the logical is to check when doing the tyres:thumb:

    Does fitting air-ride automatically up-rate the max permitted weight?

    I wouldn't have thought so Graham....So many other things to take into account like tyre loading, chassis etc.Someone might just come along and have more info on this.:thumb:

    It certainly did the job I fitted it to do.

    That was to control body roll and raise the rear end of the RV to a better ride height where the original springs has become a little lazy over the years giving reduced ground clearance.

    Certainly compensation for different loadings is possible.

    Steve.
