I just got back from picking up my truck up from the shop, had the 5100's installed all the way around.
I've only been on them for about 10 miles of city driving so I can't provide a lot of feedback yet, but I'm going on a couple hundred mile trip this weekend that will include at least 30 miles of dirt/rock/double track roads. I should have a better report by next week.
There were five(5) height notches on the front shocks.
I have them installed on the MIDDLE (3rd) Position.
The rears increased the height over my stock originals by about an inch as well.
For the record, my truck is a 2002, 4WD V8 Limited with 123k miles.
Here are some pics.
Front Height
Rear height
tire size because I know someone will ask
