What color gear/tooth count for speedo gear with 3.54 gears? - Competition Diesel.Com

SCHMITTY · 03-10-2017, 01:26 PM

I had 4.10s and swapped to 3.54s. I found a bunch of gears on eBay. I was thinking a 30 tooth since I run stock height tires.

I believe I have a red 35 tooth gear right now.

Could someone tell me what gear comes in a truck with 3.54s ?

Which Tcase? small shaft or large? I might have a green one layin around. What are they worth?

SCHMITTY · 03-10-2017, 08:03 PM

Man I'm a future Alzheimer's patient. I asked this before lol.

They are worth about 20$ on eBay with free shipping .

2.5" shaft I think. I found a nice chart hopefully it's correct. If it is my speedo should be more accurate than if I had the oem gear for 3.54 trucks- due to the tire height of the 265/75/16s. Not sure what they came with from the factory tire wise.

SCHMITTY · 03-15-2017, 12:13 AM

I'm going with a 30 tooth.

blackcloudCTD95 · 03-17-2017, 09:41 PM

What color is one for 3.55 and 35's ?? It's a 26 tooth?

SCHMITTY · 03-17-2017, 11:19 PM

Looks like it.

SCHMITTY · 03-18-2017, 12:26 AM

Damn I should have went with a 31 tooth. Before the truck was off - if I was doing 50 on the speedo it'll the truck was actually going 56 or so. Now if I'm doing 60 on the speedo I'm 56-57. I also learned that if you change the size of your speedo gear you might have to rotate the housing in clicks into. There are marks on the side of it that list gear tooth count and which way to click the housing the gears can mesh

SCHMITTY · 03-18-2017, 12:27 AM

Clock* the housing

SCHMITTY · 03-18-2017, 12:32 AM

Here is the gear size needed for a np241.

SCHMITTY · 03-18-2017, 12:35 AM

I meant shaft length. Here is the pic of how you need to clock the speedo gear holder. The np241 has a black cover and the marking are a little different but this pic pretty much sums it up. There is a little dimple on the tcase also. You can see it by the finger in the pic.
