Someone call my name?

I'll comment on two things that came up:
  1. the EHC II system w/sport pkg (S226A) & w/o sport pkg
  2. the EHC II system debut w/2002 model year e53
When you look at the part database for the EHC II air struts for the 2002/2003 3.0 & 4.4...there are 2 options for front & rear struts. There's a strut specifically for option S226A (which is the sport pkg)....then there's the strut for the S221A (EHC II). It's listed slightly different depending if you're looking at the front or rear...but there's definitely a different strut depending on how the vehicle is optioned for those first two years (02/03). Starting with the 2004 model year (10/03 build date)...the EHC II struts only have one strut option (front & rear). Hmmm.

This makes it appear that the 2002/2003 3.0 & 4.4 could be ordered with the dual axle EHC II system with or without the sport pkg...whereas from 2004-06...EHC II was only offered with the sport pkg on the 3.0 & 4.4 (and standard on the 4.8is). Does anyone else come to this conclusion?

Below is the information I have about the single & dual axle Air Suspension Systems (EHC I & II):
