FMTV High Speed Gears

[coachgeo]

I'll be honest, the 3:07 sure puts my truck right where it feels like it wants to be...., but I'm pretty sure this ratio would not be for me.

Will see how it goes...... at this moment in time am sorta with you but for slightly different reasons..... Will not really be doing any towing much; yet I want some offroad grunt to remain even though it will have a camper on back. Upping the ratio a tad also by going 49" tires, and then turning up my 3116 to 290hp like yours; am expecting will give the right balance. Not as numerically low as the 2.87:1 but little lower than the 3.07:1

Time will tell.

so confusing on what you can or can not talk about directly in here so will PM you. The seller is member here but sorta abandoned this site over the odd rules.

Coachgeo are you actually in touch with, or representing the seller??? There's too much variation in the information showing up here.

The seller with new 3.07's is on the LMTV Facebook page.

I've got no connection to it at all beside having dealt with Joe before .. he is a good fellow.

We had 2:87 chunks and a rear locker installed by Joe at MTP in Many, LA on our 2000 M1079A1 LMTV in November 2017. Joe indicated that he did not usually carry 2:87 gears. He probably doesn’t have any more. After that, with our stock engine (1999 275 hp 3126), max speed was around 74 mph according to GPS. The truck did not feel sluggish low end around town.


We recently had the 330 hp upgrade and corrected the speedometer. Best I can tell, the torque converter seems to lockup around 52-53 mph. I usually run 58-62. I’m getting about 7.5 mpg (60,000 BTU box heater uses diesel from same tank). Have not tested top speed since HP reflash. We really like the taller gears for our application. Drove some dirt roads in southern Arizona but haven’t needed low range or locker yet.

I am in need of 2 sets for an LMTV 1088 Tractor. I also have a buddy up in Oregon in the market for 2 sets for the same rig. Anybody picking them up in Texas and taking them to Oregon or Southern California? What tires do they have there in Texas?

you should look on 'that auction site'

The 1088 has 3 axles..... Are you looking for two trucks worth of gears or do you have one gear set and need two more to complete the truck? I was confused by your post.

How do we get in touch with Joe(in Oregon) for these 2.87:1 gears. Please PM me any information you have. Thank you in advance.

Delete this post...... confused two different Joes

We had 2.87 gears and rear soft locker installed by Joe at MTP Drivetrain Services in Many, Louisiana. Phone number sent by PM. At the time (November 2017), it sounded like we bought his last set of 2.87. MTP does (did?) work for the military so he may have more 2.87 gears by now.

I hope he bought more as I reached out to MTP in Feb of this year and he didn't have any 3.07 or 2.87.

I just put in an order with MTP for 2.87 gears w/ rear locker. $5,980.00(includes $1,000 core deposit). Will be ready in a week. Thank you all for your help.

EA.surplus has some rusty ones for $1,975 ea.

NEW 3.07 are available at about the sane cost and you get to keep your takeouts.

So basically the axles cost more than the whole truck.

Exactly, the cost of parts far exceeds what you pay at auction for truck! If you get a truck for $5k you may have $20k in it when it is repaired and finished.
But what a person needs to consider is the value of one of these trucks. Not the same as the cost.

What benefit are people seeking with 2.87:1 gears? Are you trying to go 80MPH?

I have 3.07:1 gears, and the >20% drop in torque (to gain the >20% speed) is noticeable. If I had the option, I would be choosing something between 3.9 and 3.07... whatever was just enough to get me a reasonable 65MPH top speed but keep as much torque from lower gearing as possible. Perhaps 3.4:1?

With 3.07:1, I don't shift into 7th until about 60-62MPH. With 2.87:1, that's going to bump up to 64-66MPH.
