Speedo Gear

[rocknutah]

How do I know what speedo gear to put in my blazer to accurately use my speedo? I have an 89 blazer with the 700r4 and 241 t-case. I am already running 35s.

You dont have a speedo gear to my knowledge I think you have a reluctor ring with electronic speedo and you have to adjust the drac to change your speedo calibration. If you do indeed have a speedo gear then the link in post #2 is a great start.
