I was actually lazy and decided to use the standard electric fan relay and temp switch you can get at the parts store. I haven’t made up my mind if I wanna spend the $100 to tune the truck yet but I probably will a little down the road. I got my new shocks on and finished the rear sway bar brackets and got everything hooked up. I’m really surprised how good the truck drives dropped. I’m happy I went with v6 springs in the front although it definitely needs some 2” drop knuckles up front and 2wd blazer brakes. Rear measures at 27” front is just a hair over 28”.
