Best speedometer recalibration tool

edwardbarnett

Looking for some insight on what is the best speedometer recalibration tool. I have looked at the rough country and the superchip version. There’s $100 difference in price. Anyone used the superchip? Any issue with the rough country tool?

I chose Rough Country as it is quite easy to use. He is worth his money. I think the value for money here is adequate. But the advice about tires should not be forgotten in any case. Even a small deflection under the weight of the car can spoil the calculations. I was lucky that I remembered this when I looked at clamps on https://www.sandfieldengineering.com/toggle-clamps/ and compared the range with my measurements. I set the correct settings in time, now everything works fine for me.

I just used the rough country on mine 2 days ago. Works great, easy install. Speedometer is accurate again as well as the way the truck runs/shifts.
