Works on my 2019 f250 with 44" tires
easy install and programing. no need for GPS anymore. I used this product because it was the only one that would go over 37" tires. That does not work very well for 44" tires.

Fast shipping
Actually didn’t use this. I returned it for something that did more than just speedometer. However it arrived quickly and appeared to be as described and I would recommend for fast shipping

Hypertec calibrator works great!
Used to correct speedometer for 37” tires. Was a little hesitant to pull the cluster on my own but the video made it easy.
