Thread: Rear airbag pressure

Hi Guys, I now you D2 guys guys are experts on this subject
Does anyone know what pressure typically their rear air suspension is running at?

I remember one of my cars had air ride shockers, and they rarely went above 80 psi carrying a heavy load.

Say for disco 2 or P38 Rangy do you know the rear suspension pressures for
i) light load running around town. ?(low pressure)
ii) reasonably load highway driving? ( middle pressure)
iii) Loaded close to GVM and used offroad, needing ground clearance? ( highish pressure).


I have a compressor in my car that cuts in at 6 bar and cuts out about 8 bar. I'm thinking those rear air bags seem to be a big diameter, so are not likely to need more than 8 bar.

Thanks for your advice simmo

Thanks guys for your responses, good info. I'm investigating air bag suspension on the rear axle, and would like to use similar parts to D 2 for ease of replacement in the event of failure. D2 & P38 are very competent off road, so if my car has the same capability I'll be happy, I don't need extreme wheel travel etc. I do need to be able to put my car under the house though to keep it out of the weather. Currently it won't fit, short term I can let the back tires down a bit to drop it a couple of inches. cheers simmo.
