I guess I dont understand how it works but I didnt think the gear guy did anything but toss in gears and diff and I went to 35s and just adjusted me speedo and its spot on.
Nice kit regardless.
With original location for ford trucks, the sensor is essentially past or after the gears but before the tires if you think of the drivetrain in a straight line, so only tire size changes affect your speedo reading.
When you move the tone ring (the little ring with the magnets) up to the output shaft, you put it before the gears, so now gears and tires will affect it.
Factory setup
engine-transmission/tcase------gears(diff)tone ring----axles---tires
