Does anyone have any specs on the gears we want?

I'm running Nitro gears in my Toyota

I contacted rushgears.com. They don't sell gears for automotive applications. They recommended:
tci automotive
motion industries

noticed a little hint US Gear's website that made me go hmmmm.... "this could be an advantage"..... appears US gear is owned by AxleTech now their email for USgear is aftermarket@axletech.com

considering axletech makes military axles too.... might make them more expensive too. but odds are they would know more about this type of axle we would be asking to have gears made for.

ok us gears has a form to request custom gears but I don't know how to answer all the questions. So I'll give it my best guess.

Does anyone else want some custom 2.90 ratio gears?

I would but as most would reply.... matters the cost.

I have found the gears listed for $1700 for a ring + pinion and I have found them listed for $2000 as well. I have no idea what the price of custom cut gears cost so I'll share whatever I find out.

 

[yertnamreg]

Yes pretty pretty please! Especially if they're priced reasonably

Thanks for doing the leg work on this.

Edit: I looked at the biggest gears they make on Jegs (10" Ford) and the gear sets run $925 each as a reference point. Anyone know how big our ring gears are?

 

[Aernan]

I'm guessing our ring/pinion are large because ARB didn't have a blank that was big enough to make a locker for them. Here are some of the details I could find:

Product Description DIFFERENTIAL - SERVICE GEAR SET Status Active Weight 102.40 Unit Pack 1 UPC Code 737238534631 Brand Meritor Marketing Group Gearsets Axle Model RSXX160 Gear to Case Fastener KIT 2426 Hardware MN, W Pinion 41267 Tooth Count 14-43T Ratios 3.07 Ratio 3.07 Spline Sizes 2.35-46 Spline Size 2.35-46 Bill of Materials: Part No : A 39898 4 Quantity : 1 Description : DIFFERENTIAL - SERVICE GEAR SET Part No : 40X1233 Quantity : 1 Description : AXLE HARDWARE - LOCK NUT Part No : 1229N1730 Quantity : 1 Description : AXLE HARDWARE - WASHER Cross References:

this one suggests we have giant gears:
Status Active Weight 102.40

I believe the diff with the gears in it weighs in at 150 lbs.

dont forget 6x6 folk. the middle axle R&P may be little different. Front and rear most axles I believe are the same. check part numbers to verify?

 

[yertnamreg]

I'm 6x6 folk

Edit: Looked at -24 and the front and rear ring/pinion appear to be amboid gears, while the intermediate is a bevel gear...or at least thats what the parts description says.

ok I found another gear maker:

I may be able to help, I'm not familiar with the exact gears you need, but I do have a Gen 1 Caiman chassis that I would sell the gears from. This is the Caiman with the Stewart Stevenson Chassis, not the Independent suspension one. I recall those are the higher speed ratio.
If that sounds like what you're looking for, email me at tdevito@dynacoil.com

I found somebody who had some high speed gears and purchased the last set he had. Thanks to all that replied to this post so far.

I am ordering a set of lockers for the rear, and then I dig in to the swap.

What seals / parts should I order before hand? Where would I get them?

does the FMTV have portal axles? Can you change the gears in the hub? I can have gears made pretty cheap.

From what I see in the TM it is a planetary gear reduction, not an offset portal style.

AECOM?

I have AECOM tin stickers on both my axle housings from depot work done at FT. Polk, LA...
