The speedometer drive gear is on your transmission (or transfer case in a W)
Any speedometer shop can change that speedometer drive gear for about $45, or sell you just the gear and you can change it yourself, but it's better to have them do it, as they calibrate the truck with a road test and get the gearing and the speedometer with-in 1%.
