I usually go to Tire Rack's site just to see what is available for a particular vehicle. They always list whichever Bilsteins that are made for it, (sometimes several different shocks), as well as what ever else they are selling. It looks like there is only one Bilstein for your truck and a couple of KYB models, including one on closeout for pennies.
Bilstein shocks are great, I have them on every vehicle I own but truthfully, if your present shocks are blown-out, any new ones are going to be a huge improvement.
Here is their page for your rig:
