Hmmmm, a lil confused on speedo miscalculation Because of my actually seeing the front diff, it appears to take speed reading off axle which if there is no tire change, irregardless of gear ratio, it should read correctly. I know on mine with 4.11s the speedo is spot on with stock tires. Just my inquisitive 2cents. Also thinking bout returning to 3.54 ratio, so looking for complete rear diff if ne one has one
