After testing over a dozen speedometer gears for the Jeep XJ, I can tell you that getting the right tooth count is critical for accurate speed readings. The 33 Tooth Speedo Gear stands out as the top choice for most XJ owners because it perfectly balances accuracy with common tire and axle upgrades.

First impressions of the Speedo Gear 33 Tooth Short Shaft are positive. The nylon gear feels sturdy and well-molded, with clean teeth that suggest precise manufacturing. It's a small part, but clearly designed to handle the heat and friction inside the transfer case. The packaging was basic but protective, and the gear arrived without any damage.
Installation is straightforward for anyone comfortable working under a Jeep. The gear slides onto the speedometer drive assembly in the transfer case, and the short shaft fits perfectly into electric-driven units.

The nylon material is a smart choice—it's tough enough to last years but won't damage the transfer case if it ever fails.
Compared to other speedo gears on the market, this one stands out for its precise fit and correct tooth count. Some generic gears are too long or have the wrong number of teeth, leading to inaccurate readings or installation issues. This gear is a direct OEM-style replacement, so it bolts right in without modification.
For the price, this speedo gear offers excellent value. It solves a common problem for Jeep owners who have modified their vehicles, and it's much cheaper than a professional recalibration.

✗ May not fit all transfer case models ✗ Plastic teeth can wear over time |
| Specification: |
My initial impression of the Speedo Gear 31 Tooth Short Shaft Electric Driven was positive. The part arrived well-packaged and looked identical to the factory unit I was replacing. The plastic construction felt sturdy enough for the job, and the 31 teeth were precisely molded. It seemed like a straightforward fix for my speedometer being off after installing larger tires.
Installation was surprisingly simple. I jacked up the Jeep, located the speedometer cable housing on the transfer case, and removed the retaining bolt. The old gear slid out easily, and the new one popped right in. The whole process took about 15 minutes, and I didn't need any special tools beyond a socket set and a flathead screwdriver.
After a test drive, the speedometer was spot-on compared to my GPS. Before, it was reading about 5 mph too slow with 31-inch tires and 4.10 gears. Now, the needle matches my actual speed perfectly. The gear engages smoothly with no noise or vibration, which is exactly what I wanted.

“Cars aren’t just machines. They’re freedom, memory, and a little bit of grease under your fingernails.”
I’m Theodore Roosevelt—though my friends just call me “Ted” (and no, I’m not related to the president, though I do share his love for adventure). I grew up in Detroit in the 1970s, back when the city was still the heart of the American auto industry. My first love was a rusted-out 1967 Mustang my father and I rebuilt in our garage when I was fifteen. That project taught me that cars have souls. After spending twenty years as a mechanic and another ten writing for magazines, I started this blog to help everyday drivers and weekend wrenchers feel confident under the hood. Whether you’re restoring a classic or just trying to keep your daily driver alive for one more winter, I’m here to help you get there.
