I replaced the two rear shock absorbers on my 2011 B200 turbo which has 143,000 kms and found that it made a significant improvement - a lot of strange noises have been eliminated and Iwould like to renew the two front shock absorbers as well. In addition the front suspension seems too low because I have bumped the chassis on relatively low humps in the road. I would therefore like to replace both front springs and shock absorbers and at the same time go for an option for greater ground clearance. Searching various bits of information I came across a "code 484 chassis packet for greater ground clearance" and I would be most grateful if any readers could provide more details on how to get details of the code 484.
