OK, guys, I am regearing to 4.88 next week, and I am now looking for a 44 tooth speedo gear to calibrate the speedometer when I do so (I am running 31" tires, so according to my calculations, this is what I will be needing). The problem is that neither quadratec nor 4wd carry a 44 tooth speedo gear. Any suggestions on where to get one?

This site says you will need a 41T...has all of them for sale...no 44 though??

They sure are proud of their gears. Dealer only charges $10-12. According my my chart, he's need a 43T which I don't think they make. I doubt a 41T would get him back to stock.

The stock one is 41 (which I still have in my garage), but according to my calculations, that should be perfect for when I step up to 33" tires.
I got a 38 in right now, and it is within 1mph acurate; according to my calculations (and it conicides with the charts in quadratec.com (http://www.quadratec.com/jeep_knowledgebase/article-46.htm), and many other sites like this one (http://go.jeep-xj.info/HowtoSpeedoGears.htm) or this one (http://www.redrock4x4.com/tech/speedo_chart.php)), for 4.88 gears (changed from 4.10) I will need 44 teeth.

But at least they have 43 teeth here, so that may be close enough! (in quadratec and 4wd, they only go up to 41). So even if I have to go with 43, at least it will be much closer to reality than the 41 I currently have.

I have to check if the dealer has any 43 tooth ones... If they do, I may go with them. For 44T, I may have to have it fabricated (I know of a place that does this, but dont know the cost; if its more than $30, I may just go for the 43T and call it good!).

Contact www.tacomaspeedometer.com , they can let you know the largest gear possible. They are great to deal with, decent prices and quick shipping.

They did not have the 43T one, but they told me to try with the 41T one. If that is not close enough, I'll get the 43T one from the dealer.

By the way, when the speedo is showing 65mph, the GPS is showing only 55, so I am way off!
-
Mine is like that now as I have the super short slip yoke eliminator...I will have to buy the electronic module from Superflex?? to fix mine...attaches in-line to the wires from the speedo sensor.

That means it's still spinning too fast with those piddly little tires. :wall:

The other option is to change the setting in the PCM, which requires a programmer. Dealer only.
-
I think the best fix will be to put the 41T gear and 33" BFG M/T's as it is suppossed to have in the first place (but, of course, my wallet is holding me back!)
-
the dealer cannot adjust for tires over 31"...or maybe 33". You need to get an aftermarket programmer for $200 if you want to change it yourself.
-
Well, I put the 41T gear in, and I am still about 5 mph off at 55 mph, so I guess I'll try the 43T next (I'll call the stealership and see if they have any in stock; if not, I guess I'll have to pay up at the site Moz recommended, as it's the only one that seems to carry the 43T gear).
-
Did you check with Tacoma Speedometer at the above site?

I called them, actually, but they told me that they did not have the 43T in stock. They told me to try the 41 (I have that one on right now, but I am still about 6~7 mph off at 60mph), and se if that works, but now I'm pretty sure I need the 43T.

You need the 43T like someone said before. :whistle:
-
Yup. I already ordered it. Unfortunately, the stealership had to wait like 2 months to get it, so I had to order from Moz's site ($$$!!!)
By the way, I still think the perfect tooth count would be 44, but that would be even more expensive, as it would be custom made (has anyone noticed that the TC can accept all the way up to 45T?).

During one of my searches I found a programable electronic box for the speedo that works with any Jeep that was about 60 bucks before shipping. It would make for a flexible alternative, so when you change tires you just reprogram it

Well, I wanted to keep the cost low; besides, when the 33" tires go in, the 41T gear will get me to where I am suppossed to be...
