This kit contains a 6 tooth drive gear, a 19 tooth driven gear, a driven gear retaining clip, and a drive gear retaining clip. This is the most accurate gear combination for a T5 car equipped with 4.10 gears.
When you change the rear end gears in your Mustang you will need to recalibrate your speedometer by installing a new speedometer gear. Our Mustang speedometer gears are inexpensive and only take a few minutes to replace! Check out our speedometer gear installation instructions for a full write up with pictures on how to change the speedometer gear in your Mustang.
Works perfect and install is simple. Definitely need to change both internal gears when installing gears taller than 3.55 if you want the Speedo to read correctly. If you just change the smaller Speedo gear,you will be close, but still reading the wrong speed. Change both and you will be reading the right speed.
Yes, I would recommend this item to a friend!

Testimonial: Coyote swap parts a step above the rest.
Late Model has made choosing the right parts for my coyote swap fox body much easier. With a dedicated section for this type of build and constantly updated with the latest parts it was a clear choice for me. They even did they're own swap with instructional videos. Thanks Late model!
