Hey,
Glad to see you on here, great bunch of people to talk to. The coil spacers they are talking about are factory ford parts for a 93 f-150, about 35 bucks at the counter for both. For the rear you have 2 choices, add a leaf- pro comp from 4wheel parts for 29 bucks, or shackles, some use the ones from auto zone, others use the warriors, I have a set coming now for the sport. Using that type of lift with the trail master body lift, you can get it up close to 5 inches for around 200 bucks. Best you will get with that is 32's, or maybe narrow 33's. Your ex looks really good with 32's, few members here that have a 4 inch lift with 32's, and I think they look good, that is what I am putting on sport now with the long travel kit till I can do the sas. Call me if you need help, I have done just about every type of lift you can do on the first gen explorer. One more thing I almost forgot, rough country right here in Dyersburg sells 1 1/2 inch coils for 109 bucks a pair, more pricey than spacers, but gives you new spring, btw, spacers are metal, and very strong.
If I left anything out just ask, or try the search feature, tons and tons of good info thru out this site.
