[QUOTE=OnTouring;1101353]Hi all.

I've come into acquisition of a rear pair of Arnott Sport Air Springs, and in checking around it appears even with the VIN-specified S221A (4-Corner) and S226A (Sport) suspension packages, all 4.8is models are equipped with 'Comfort' air springs instead. Is switching this a 'no-no?'

1. What is the difference between the two, comfort vs. sport? Does anyone know?
i.e. Height? Diameter? Air capacity?

2. What happens if I put these sport springs in? Am I risking anything "bad" happening?

No You have SPORT suspension , I just changed mine last month.
