        Speedometer gear

        Yeah works perfect. It took longer to get it up in the air than it did to install. Bought several of these from American Muscle.

        I love American muscke and have ordered quite a bit from there. I called in and told that I have 4:10 gears, and was set up with this. It works well and correct the speedo! Super easy and straight forward to install as well!

        Great price, right part first time...

        Brought my speedometer right into perfect calibration! Prior owner had replaced the OEM 3.27s with 3.55's. For me, recording the correct mileage is key for a limited edition car. The tech support team got it right the first time!!!

      I have 1998 Ford Mustang Gt auto ...what type of tooth I need ?

      I have a 1994 cobra with 3.08 gears, which speedo gear do I need to calibrate for 3.55 gear swap? Thank you.

      • You would need a 23 tooth gear, which we do not have to offer.

      I have a 1994 Mustang GT T5, and will be installing 4.10 gears. I'm unsure if i need only this product to correct my speedometer or if i also need a speedometer drive gear??

      • You would need a 7tooth drive gear and a 23 tooth speedo gear.

      Ok, having trouble figuring out which speedo gear I need. I own a 1991 Mustang LX 5.0. Manual Transmission Coupe. Running 225/55/R16 Tires Checked the Rear axle tag and if I’m reading it correctly I have 3.08 gear ratio 8.8 diameter.. I have to assume the o/e gears have not been changed as I bought the car with 50,000 original miles. It Had sat in a garage for 12 years undriven.

      • The 20 tooth speedometer gear will work for a 1991 mustang LX with a OEM T-5 transmission and 3.08 gears. If you have another transmission than that would require another speedometer gear.
