I checked out Summit Racing's website and they offer a leveling kit (2.5") that's branded as their own. I heard it's actually made by Skyjacker-anyone know if this is true? Anyway, it comes with two new springs, four U bolts, and a new track bar mounting bracket. I have a couple of questions though...
In the online directions they state that you can reuse the stock shocks and brake lines

I was planning on doing new shocks anyway, but will my stock lines really be ok with 2.5" of lift up front? My front end is sagging a bit so it's hard to tell how much travel is actually left in the stock lines. What kind of shocks should I get?
I'm planning on doing the leveling kit, swaybar/trackbar/leaf spring bushings, ball joints, u-joints, an oil change, and maybe even Warn hubs the weekend after next because the GF will be away all weekend visiting family so I get to play in the garage all day. Anything else I should do/check out while I'm there? I just hit 85K miles so I'm starting to think about all the big services I should do on the way to 100K to make sure that I'll be taking this truck all the way to 300K
