Where to buy an NP205 speedometer gear

I need the plastic gear for my NP205 that goes on the output shaft. I'm assuming this is the one that needs changed for larger tires. Any thoughts on where I could get one of these?

I guess these same places could tell you which one you need for a particular gear ration tires size combo?

Yes the PBB embraces Newbs with the most basic questions and lack of technical expertese to use the search feature in General 4x4. Would have been fine in Newbie 4x4 to ask such a question.

Did you try Google ? second one in that list of "Results 1 - 10 of about 2,290. Search took 0.42 seconds." looks promising.


Ohh here is a bone.

The color is used to identify your gear ratio.

Whenever I reach the member pinnacle of having 100 posts, and I'm no longer a Newbie, I'll be permitted to ask questions in General 4x4. These divisionary tactics are unique to a Newbie such as myself. Perhaps the entire notion of being a Newbie is clouding my mind, forcing me to consider the logical... .

Anyway, none of the dealers have speedo gears for 35" tires for the NP205. Looks like I'll need a conversion box.

Uhhh I don't like them. They are not sealed very well and tend to get water in them. Then they freeze in the winter and snap off in the peice on the case.

Ok another bone the orange gear and 4.10 is dead on with 32's. I'm too lazy to sit down and figure out what the ratio is to get the percentage off to figure out the next gear up. remeber that the size on the side of the tire is rarely what it actually is. BFG 35's on a 15x10 rim are pretty close. 34.75. Bajaclaws are about lucky to have a marked 35 be much over 33.

With BFG KM's 35's on 10 inch wide rims with 4.10's it's 6mph slow at 70mph as compaired against a Garmin GPSV with external antenna on the orange gear. I think Yellow is about 4% higher and just guessing about right but it's been a long time since I have seen a chart.

Most of use just use this as an excuse to get a GPS anyway.

Are you referring to the color of the drive gear or the driven gear? GM and Ford have told me that the only drive gear available is an 8-tooth piece, in metal or plastic. It's the same one I have, and it's red.

My driven gear is a 19-tooth metal gear (obviously, no color). I suppose that I can use one of those speedometer gear equations to calculate how many teeth the new gear must need. I'll have to ask the dealer how many different types of speedo gears they have, instead of one to fit my exact application. My description to them of "35-inch tires with 4.10 gears" may correlate to another configuration that matches.

I want a GPS really badly .

A link to the colour code chart to match the gear ratios would be pretty cool as well, seeing as it was brought up.

your tire size is only a part of the equation for speedo gearing
