The F250 shock mounts allow for a much longer shock, which is required to gain the most travel for the axle arms of the TTB front end. With the stock Explorer mounts, you can only fit a shock with about an 8" travel range. By extending that shock upward into the fender well, you can fit a shock body that will allow for a 12-14" stroke, which at the end of the wheel will get you about 18" of total travel -- mostly downward.
To get the most benefit, you will also need to use some coil springs with more travel potential (I used 1977 F150 springs, which are softer, and travel more), plus longer brake lines (Any late model SuperDuty will work great, as do Jeep XJ lines). To get radical extra travel, steering modifications will be needed as well.
One further note, I didn't incorporate much lift with my suspension -- it was mainly designed for travel. I only had about 3" total lift.
