Actually, I've used the search, but didn't quite find what I was searching for. The 4'' thread input actually helped me decide on a lift better than the ones that the search engine found. I did look thru the SAS registry and found lots of info about time and parts, but I didn't get a clear $$ amount for the swap. Sorry to offend you. I've learned in the past when I used to drag race my Mustang, it was better to ask more questions if you didn't FULLY FIND what you were looking for esp. when you were about to spend thousands of $$ and time to lower your E.T's. Again, SORRY ROBB. I'm sure your "Reality" is better than mine since I'm new to this Explorer website. Please accept my apology.
