speedo recalibration on 96 - 98
 

can anyone link me the places to get the correct speedometer gear to replace the stock one when you get aftermarket rear end gears?

any Ford dealer (like us:D )but you'll need to know what gear (# of teeth) is in the trans now and we can adjust up to a 21 tooth, each tooth is @9 mph

thanks randy, i just need to find out which gear works with 3:73 diff gears...where would i go to find out?

do you have an auto or manual trans?

automatic.

well, we can prob get you close wth a DOOZ-17271-B 21 tooth speedo gear, depending on rear tire size, it still might be off 9mph or-so....

if i swap with a GT 8.8 rear from a '98 with, say, 3.55's, how close could i get to getting a correct speedo with the right gear?

well, wth 3.55's we can get pretty damn close, you can also look into a Speed Cal, which will adjust for just about all gear ratios and tire sizes
