Gears came in, where to get speedo reset?
After I have the gears put in, who do I take it to to have the speedo reflashed to proper settings? I have an SCT but I don't believe hemifever can fix my problem?

because your 2001 speedo is driven from the ring gear tone sensor in the diff, i don't think the gear change is going to affect your speedo.
what does affect your speedo is big tires. the solution is to set the "pinion factor" in the pcm. hypertech (sometimes yes, sometimes no) and superchips will adjust speedo. SCT tuner will not. Dealer can, but they have to skip the pre-programmed settings for 225, 245, 265 tires and go to "other" and then input the correct revolutions per mile. some know how to do this, others don't.

Later model year Dodge Rams (at least for 1999-2001 model years, if not earlier) do not have to be speedo corrected for gears. Only way a vehicle doesn't need to have the speedo recalibrated after a gear change is if there is a speed sensor in the differential, which is exactly where ours is located at.

The speedometer will not be effect. The only thing that will change is the rpm readings on the tach. If you go with a taller gear the rpms will increase. If you were showing 2Krpms @ 60 mph before the gear change then after the gear change you will be showing increase in rpms while at the same speed. How much of an increase depends on how much taller you went with the gearing.
