Truck is a 2002 Ford Super Duty 4x4 diesel with the 4 speed OD trannie and I believe it came stock with 3.73 gears. Been giving some thought to having the gears changed out to either 4:10 or 4:30's to help the towing performance.
It does "ok" when towing our Sea Sport now but does feel a bit sluggish hence the possible gear swap. We never drive over 60 mph when towing and usually hold to 55 so the higher cruising rpm shouldnt hurt the mileage at all. Currently getting about 11-11.5.
Has anyone here personally had a local shop do a gear swap out? I know swap outs can be tricky due to shimming them properly so am looking for first hand information.
