Overview
The 53001492 is a red speedometer gear with 19 teeth. It fits the 1984–1990 Jeep Cherokee (XJ) and the 1987–1990 Jeep Wrangler (YJ).
A speedometer gear with the wrong tooth count makes the MPH reading differ from actual speed, most often after the tires or axle ratio have changed. The 19-tooth count is one choice for correcting that reading, and the right count for a given build should be checked against a tire and gear ratio chart.
Key features
- Red finish, 19 teeth
- Fits 1984–1990 Cherokee XJ and 1987–1990 Wrangler YJ
Matching the gear to your tires
Speedometer error comes from the ratio between the transmission output, the axle gearing and the tire circumference. When any one of those changes, the reading drifts, often reading faster than the true speed. Gear tooth count is one way to bring the reading back, but the right count depends on the whole combination rather than the gear alone.
Before swapping gears, measure the tire diameter and confirm the axle ratio if it is known. Work through the combination on a ratio chart and check the result against a known speed on a road you trust. Inspect the speedometer cable and drive housing as well, since a worn cable can cause erratic readings that look like a gear problem. Keep the old gear so the change can be reversed if needed.

- Note the axle ratio stamped on the tag
- Check the speedometer cable for kinks or wear
- Confirm the reading with a known speed
