Gonna order 4.10's, what about speedo?

[Blk01gt_]

I know you have to get something to adjust the speedo when you do gears, but what exaclty is it and where should i get it? Speedcal or speedo gear or something? My car is an 01 GT.

I hit a curb so i took it to ford for repair, they said i bent the diff. housing, so im gonna get them to put in the 4.10's while theyre back there. Think a ford dealer should be able to install the gears properly? I guess they should know what to do with the speedcal or whatever it is for the speedo calibration also?

Thanks

speedcal or an ECU reflash...

i recommend ECU reflash as well.. it will do more than the speedcal

Can the ford dealership do this ECU reflash?
How much does it cost?

I called 4 local dealers and none of them said i could reflash the ecu.. they responded to me as if i was a retarded low-life who didn't know what i was talking about.. so i got a dyno tune.. gives a more exact recalibration since it matches the dyno's speed, plus advanced timing, exacted A/F ratio and turned off rear 02 sensors for my catted X. i think its worth the extra money if you've got some other mods that can benefit from a tune
