I chose the BDS 6" basic kit and then the upgrade to Fox Shox. The tires I went with were Firestone Destination MT in 35/12.5R20 and added a set of 1.5" hub centric wheel spacers to correct the track width.
The lift is awesome and seems so far to ride better, of course because I did have 2.5" rough country level.
The tires are the best part though
1. They are uber aggressive looking
2. They are cheaper than any other tire I was able to find
3. They have some of the best reviews against all tires when looking for MT tire reviews.
Front fender height was 39.5 and now 43.5
Rear fender height was 40.5 and now 44.5
I am really glad I stayed with my SLT chrome 20"s cause I absolutely love how my truck turned out and I think the tires stick out just the right amount.
