I am running these currently. By far the best shock that I have ever put on my truck.
I have a 6in lift and am running 37s. Here are the part numbers for what i have,
Bilstein BE5-6249-H5 5100 Series--Rear
Bilstein BE5-6248-H5 5100 Series--Front
One thing of note, these do not come with new shock studs. The last set of shocks that I ran were Trailmaster and the included new upper shock studs for the rear.
