I have run rancho RS5000's on most of my trucks, current truck has procomp ES9000's, duals up front and singles in the rear. Bilstein makes a great shock too. Buy a set that look good on your truck, the chances you'll overdrive your shocks on a daily driver are slim. Someone posted a link in another thread for Bilstein shocks, I was surprized that their prices were comparable to Ranchos.
If I were buying new shocks today they would be Bilsteins.
