Does anyone know where to get gears to recalibrate the speedometer on a toyota. I know they make em for jeeps but have never seen them for toyota's. Any one know??

I know that Sleeoffroad sells them for FJ80's but I don't know if it will fit the pickup. They look the same though.

Inchworm,

Is it just the inserted gear that is different. It's been so long since I tore down one of my cases I can't remeber if the output shaft gear is replacable. I'm in the same boat, I would like to recalibrate my speedometer.

Yes, the output shaft gear is replaceable there are at least two tooth counts there (I know there are 6 tooth and 7 tooth gears. There may be others.), and then a few different tooth counts on the plastic inserted gear. (18, 19, and 20 tooth. There maybe more of these also)

All of this is off the top of my head, I guess I ought to dump out my bucket of speedo gears tomorrow and see what I find.

If you can calculate what you need, I may have it. Let me know what you are looking for and we'll see...

Inchworm,

I like your idea but the problem is I am running 35in tires and 4.56 gears, that's why my speedometer is off so much. I will go ahead and see if I can figure out what ratio would work and you may have it.

I don't know who makes it or where it came from, but when I bought my 86 4Runner it had an adaptor on the speedo-cable input to the tranny. It screwed in where the speed-cable would, then the speedo-cable screws into the adaptor. It corrected my speedo with 4.10s and 33s and this is varified by GPS. I sware it was the most accurate thing ever <IMG SRC="smilies/smile.gif" border="0"> At one time I was geared to 4.88s and running 33s and my speedo wasn't as accurate as it was with the adaptor, 4.10s and 33s. Now w/35s and 4.88s my speedo is more accurate...must be a GPS thing <IMG SRC="smilies/smile.gif" border="0"> I wish I had a digital camera to show you guys what it looks like.
