I have a 2000 AWD Expedition, I cranked up the torsions while on race car scales until the cross weight was 50%, in stock position they seem to have the truck set with a lot of left side weight, after the weight was correct I turned in about 5-6 more turns of torsion on the key adjuster. With that you can install 285-70-17 BFG T/A KO's on the stock wheel and there are no problems. I have that set up right now. I did nothing to the rear, so the front sits a little high like a "prerunner". Hope that helps. |
