How to tell what gears I have?
Hey guys, I bought my truck used and it already had a 6" lift on 37s. I'm curious what gears I have on my truck and want to know if the prior owner switched them from stock. I haven't gotten a programmer yet so my speedo hasn't been calibrated for the larger tires. When my speedo says 55mph I'm down around 1550-1600rpms. And when my speedo says 55mpg I'm actually going about 60mpg calculated by gps. Anyone have an idea of what I've got? Also, if I pull the rear cover off how do I go about calculating my gearing? Thanks!!!
