Rugged Ridge18760.15 Speedometer Drive Gear, 33 Teeth, Short

Worked as described. Installed it fast and was up and running in 30 mins

My 1999 TJ Wrangler speedo was under reporting actual speed by 10% (checked from two apps and other cars), due to taller/higher wheel (rim and tyre) dimensions 245/75R17 (two inch lift). Used an online calculation based on new tyres and wheels and differential (3.73), ordered a replacment cog with 33 teeth. During removal of the old drive gear, discovered the OEM was 36 teeth which was installed for smaller dimension wheels (215/75R15).Result, perfect! Now my speedo is exactly reporting the correct speed (within what I estimate to be 1-2% at 100 km/h.Purchased and installed a new rubber O-ring and everything was completed in less than 15 minutes with the right tools.

Works as advertised. Easy install. I measured the height of the tire not the advertised tire size. 33X12.5X15. The tire is not 33 inches tall.

I have a 2004 rubicon. Which this will not fit. But I have used these before on non rubicon models and work great.

I had this part in my inventory on a Jeep build. When it came time to put the transfer case back together I went to install and found it was pretty much shredded. All the gear teeth were torn-up. It was of course after the return deadline and I had not inspected it prior to installation. It appears that it was returned because someone didn't know how to install it properly, or tried an incorrect application before returning it. I have no complaint about the product itself, but the "like new" description was far from accurate.
