        What speedo gear set is needed for a T5 with 3:73 gears and a 140mph speedo in a 1988 LX efi with mass air conversion.

        • For a 1988 Mustang with a T5 and 3.73 gears, you would need a 21 tooth speedometer. You can find that here: https://www.americanmuscle.com/speedo-gear-21tooth-manual.html

            Just what I needed!

            Old speedo gear was badly chewed up. This one fit right into place and got my speedo working again.

            Takes longer to get set up than to install. Love the calculator to find the right gear.

            Perfect

            Perfect fit for my foxbody , just make sure you get the right tooth gear for your rear end. Could be difficult to find out but I just did my research

            Fits great!

            Very cheap add-on to give you the correct readout on the speedo for your gearing and tire size. make sure you find a calculator to determine the tooth count using gearing and tire size. If not, you can be way off.

            Correct part, but not for my set up

            After purchase my stang, I notice the car will run to hi in RPM, well it had a 3.90 gears, I changed to 3.73 and try to correct the speedometer with a new gear. I call AM and a service rep was really helpful and after some digging he told me that I was in need of a 18 tooth gear! well got it. Well for my luck the gear work fine but the speedometer is still out of whack, my tranny gear is an 8 tooth not 6 as I and the service rep though. Overall is a great product and is a Ford OEM part.

            • Response from AmericanMuscle

              If you have an 8 tooth drive gear (which would be stock in either the manual or auto for the 1997 GT), you would need this 18 tooth speedo gear as well as the 6 tooth drive gear to correct for a 3.73 gear ratio upgrade. So you didn't buy the wrong part, you just didn't get everything needed unfortunately. Installing the 6 tooth drive gear would correct your speedometer. If you have any further questions, please don't hesitate to give us a call.
