Bilstein 5100 series worked great on my 06' before it got totalled. If you have a lift on the truck I have a set of brand new ones for the rear that work with 4" lifts.
Ranchos work great... Bushings are a thing of the past with them. The 5000, 7000 or 9000 are good choices, and lifetime warranties and are probably one of the best bangs for the buck out there.... Half the price of most high end shocks
Bilsteins are excellent, I was looking at options for my truck with a heavy camper and they were on the list. However, price, availability, and support all ruled them out. They are quite expensive-$900 for my truck (no lift, and non-adjustable), availability-not even able to find a shop that supplies them, and support-no shops-no support. Rancho's aren't necessarily the best, just the best I can get for $600. And Napa, Bumper to Bumper, and Off Road Interior all deal with and can warranty them. The adjustability is easy, 1-9 makes a huge difference in ride, and the boots are substantial and very protective. For my use, the best bang for the buck, that's all I'm saying.
