Do yourself a favor and make sure you remove the axle nut and swaybar end links. It makes the installation so much easier. As shipped they raise the front 2" & if you want it higher adjust them before you install them.
I find it easier to fill it with a half tank left. Call me old school, but it was ingrained in me by my Dad to always have gas in it incase of an emergency.
Have you considered 265/70R17? there are u bunch of options out there in that size. I installed Goodyear Ultra Terrains and have been very happy with them. I think they're a Discount Tire exclusive so that might limit your choices
There are many options for good shocks available for the Ranger. I've read good reports from Icon, Fox, Eibach & Bilstien. I installed an Icon stage 3 kit with reservoirs on the rear because they met my needs and am extremely happy with them. Read more members posts & choose what you feel is...
I have the Icon Stage 3 and couldn't be happier. IMO they did a great job with the compression & rebound valving and made the front and rear work together as they should
