Having dealt with so many times and about to deal with it for my truck also, here is what I recommend.

1. Go with something that is gas based not hydraulic, gas offer a better performance and feel without the jerking/jolt feeling.

2. Go with something that is adjustable externally. The adjustable valve is located on the outside of the shock and accessible without removing the wheels or body parts. There are times when you want to soften the ride out a little or stiffen it a more than normal.

3. Go brand name and check the warranties. It is worth spending a few extra dollars on something that has a good name, good specs, and a warranty policy that does cause a ton of grief on replacement.

4. Get a set of poly bushings to replace the rubber ones supplies. This will add to the performance and better positive feel by making the shocks do more vs the rubber deforming.

Bilstein are good and I would shop around for their higher end units that offer all the above.

Congrats on the price, I got a great deal on mine also. Our local dealer had a loaded 08 6.7L 4x4 quad cab with 8 miles on it, after reviewing their zero sale board for the month, I told them if they made me a good enough offer I would take it. Well after leaving once, they gave it to me at 1/2 off with 7 year warranty on the whole truck

Welcome aboard !

Cheers,
