Calibrating Digital Speedometer

[Longhorn1500]

Hi. I have noticed that the digital and analog (the one with the needle) speedometers do not agree. The digital one reads about 2 mph higher than the analog one. I think the analog one is more accurate because it agrees with the GPS speed. Can the digital one be adjusted? Thank you.

Yes, Rough Country has a Speedometer corrector...I used one when I added 35's

Be careful you don't have a faulty cluster. My truck had the analog speedometer which was actually faulty and the digital was correct. I set the cruise control and the cruise control speed and it matched up with what the digital one who said, and my analog was showing 3-5mph slower.

The digital one matches the cruise control speed. The analog one is about 2 mph lower at 60 mph. I think the analog one is correct because it matches the GPS speed (which is independent). No big deal, it would be nice if they matched though.
