Question about what e53s came with full air suspension

[4.8isX5]

Intresting,, @qsilver,,

Mainly the last part, if i remember correctly from a post made here i read thru before, the correct bags go get for the rear of a 4.8is for example was the comfort ones? Is the 4.8is full sport meaning sport bags rear and front?

On a side note, i see people replacing the front struts/bags and rear bags.. Anyone replace the rear shocks? Its normal to replace them on other cars just as the struts but i dont see if talked about much, where do you get them as well cause i dont think arnott sells them.

1. Yes, the air bags for the EHC II system (10/2003-up build date) are the "comfort" bags for the 3.0/4.4/4.8is (especially when looking at Arnott's web site). And again, all 3 of these models have the "sport pkg"...and even though the air bags have full "comfort" articulation (highest to lowest suspension settings)...these vehicles (so equipped with EHC II) are "coded" with the sport pkg suspension (lowered stance) setting as its default.

This is another reason why it seems confusing that the 2002/03 models with EHC II have a specific air bag if optioned with the sport pkg (S226A).

2. Since the full weight (axle load) is borne by the air bags...this means that the shocks/struts only serve an ancillary/support function. Would they "wear out" at the same rate as the air bags? Or would replacing them depend on if they are actually worn out or not performing up to par...or if the owner opts to change them along with the air bags (which are bearing the full load)?
