Speedometer Calibrator for refresh models

[ZR2]

Just came across this speedometer calibrator for our trucks. It’s expensive and a hassle to install, not like plug program then unplug.

I don't own a 1/2 ton...But I never used these on my 3/4 tons, because most of them came with 33's, I upgraded to 35"s, which kinda worked out to about 3mph difference at 60mph. Didn't really care about it.

I've done some stupid shit to my vehicles, but not sure I have the balls to put a Rough Country product inline with my TCM and Brakes at the same time, then go drive it 80 mph down the highway.

Must be fun to hide during warranty visits.
