Omix | 18760.27 | Speedometer Drive Gear, 39 Teeth, Short | OE Reference: 52067639

So I had a set of 4.10 gears installed in the rear end of my Dajiban. The speedo was, as one would expect, wildly inaccurate after that. I consulted the intergoogles and discovered I needed to swap my 34 tooth pinion for a 39 tooth pinion. So I ordered it. Of course it arrived on a rainy, cold, miserable day, but I couldn't wait. I crawled under the van with a 13mm wrench, cursed the guy who told me I needed a 13mm wrench, found the correct bolt, un-cursed him, removed the old pinion, popped the new pinion in, and bolted it all back together. All in, fifteen minutes "work" to install. I took a hoon up onto the freeway and the odometer clicked exactly the same tenth at every mile marker for about five miles. The accuracy is astounding! So, if you need a speedometer pinion for a Dodge, this one is a good choice... well, I mean, you need to figure out YOUR tooth count needs, but once you do, this is a good choice. Sort of thing.

I changed out the gears on my 1998 TJ from the stock 3.07 gearing on 33" tires to 4.56 gears on 33" tires. Spot on now!1 bolt to pull assembly pop off the old gear snap on the new one and reinstall. Time it takes to install - 1 beer.

it took just a minute to correct the odometer, one half inch bolt on the transfer case on the old TJ wrangler. had new gears installed, jeep has 488 gears with 35" tires...

It’s weird - mechanic says this is not the right part for my 2004 tj but advertised as compatible. Fortunately for me they had great customer service and I got my refund right away . Thank you

Replaced the stock tires on '03 Jeep Wrangler with 3.73 gears with Mickey Thompson 35x12.5 with 4.88 gears which caused the speedometer to be extremely incorrect. Replaced the speedometer gear with this one and now my speedometer is very accurate. Job took less than 30 minutes from start to finish. Really was impressed with the change.

I had regeared the Jeep and needed this to fix the speedometer reading. This did the trick. It's not something that can be seen as it is a hidden decor on the inside of the transmission but it does function as designed.

Installed this in my TJ..it helped get my Speedo reading properly after installing the 4.56 gears w my 33”s

Easy 5-minute install on your Jeep. Make sure to pick up a seal (preferably OEM) as well.
