If your are bound to go it on your own; Fox, FOA & King are your choices. FOA has a shock sizing site but nearly takes an Engineer to understand. Easiest is work with Off Road Warehouse http://offroadwarehouse.com/contact . You can call the 800 # and ask for Nick or the shock guy. He is the shock guy and will work with you to make your purchase. Prices are very good, bought mine from them, & service is excellent. If you go thu them I would recommend Fox Shocks. I believe Flatbed also worked with Off Road Warehouse when he upgraded to Fox. Maybe Kinarfi will post how he purchased his FOA shocks. Of course Lenny blazed his own trail, LOL.
Forgot to mention, Shocks are the easy part. It is the springs that are a pain!
