Assume all true and accurate...then those very things also weigh more...therefore
reduce the available weight ratings for towing...
Most all GM trucks have the G80 locker option and comes with most option packages
Those shocks are better than OEM, but not as good (normally) as good after
market shocks. The GM magnetic fluid shocks (yours are NOT them)
are pretty good, but once they leak, they are EXPENSIVE to replace. As
there are no after market supplier for them When they first came
out...they were around $800/each and I'd rather get Koni's at a bit
lower price...but way better
Most of the stuff you mention has more marketing verbiage than specifications...
Frame mounted skid plates are the way to go, as the El Cheapo component mounted
skid plates are just that...not as good a d frame mounted on. Component mounted
will have the component's frame mounting points crack when hit hard enough
Appearance package...AKA 'looks' package
Nothing wrong with the stuff you like/love...but to an old time Gearhead/Wrench/Boy Racer...
this stuff is pure marketing verbiage...
