here is my parts run down.
spacers(used): 200
body lift (ebay i think): 220 shipped
upper arms:550 plus shipping
rims (went overboard and got 20s so 16 will be alot cheaper): 1450
35 inch mud grapplers:1300+shipping with hazard warranty
longer sway bar links for the front and rear:about 100
so i spent just about 3500-3800 for everything but i didn't exactly go the cheapest route.(tires and rims mainly)
i also just went ahead and did wheel bearing just for the hell of it. i figured i already had the front apart i might as well finish the passanger side up with a new wheel bearing.
the reason why RB doesn't sell the 3 inch spacers anymore is do to the fact that some vehicles had issues with them. its all up to you with what you wanna do but i might move down to 33s after my 2 sets of 35s are finished. if you do plan on using it for off roading then stick with 33s also. this will be the wifees vehicle when its finished so its to her liking
wheelspacer= ebay just make sure they are hubcentric for explorers, sway bar links= i can't say where i got them on this site, and upper arms are from another guy on here that made them but he also got banned sooooo. its tough hahah
