Speedo gear
Replacing a leaky VSS and figure I might as well replace speedo gear. I am using a 20 tooth and my speedo reads slightly low. Do I go up, or down a tooth to make speedo read slightly higher? Calculators say 20 tooth is the one. Thanks. |
Probably need to go with the 19-tooth (PINK) gear if you are using a 3.27 differential. https://performanceparts.ford.com/do...UsageChart.pdf

Hi Brad,
a better alternative for accuracy is the dakota digital speedo interface. You can then adjust speedo up or down as you drive using your phone gps as a reference. Any change in gearing, tyres etc. Can be adjusted from the cabin by clicking a button...might be worth considering. Alternatively fordcracing or late model restoration have a speedo gear calculator which will tel you which color speedo gear is the closest match. It will still be inaccurate to a degree.... That's why the Dakota unit is worth the money and effort...same for their tacho interface. Makes the conversion see simple 😊 cheers |
I ended up just keeping the 20 tooth gear. It only reads ever so slightly low. Not a big deal. |
