Another way to lower an M1101/M1102

[drivebymashing]

I dont think you can really put more than 2k in one stock. Ive loaded my 105 with an insane amount of weight. Ill load mine up and weigh it and see where the tires go.

I think they're rated for a payload of 2740# max.

I have put 3000 lbs in mine and it wasn't on the stops and towed great.

Ok the heaviest load I hauled was a stack of lumber 16 feet long. The tail was wagging the dog like crazy. I couldnt go over 25mph. Ok good to know it will handle 3k.

The problem with that load was the balancing the center of mass was on the tailgate, bad loading. The center of mass should always be over or slightly forward of the axle. They will handle more than 3000 lbs but it is not good for it.

As with all military trailers.

I've had a multifuel in a can(3100ish lbs) in an M101. It handled it, but didn't like it.

I see a consensus that they are the same. It would be interesting to see inside the axle. Only a few inches would change the rating and it's in a spot that cannot be seen. I wonder if the manufacturer says they are the same. I understand the reasoning, re the tow vehicle authorization.

The axle on my 1101 has a rating plate on it indicating a max load of 4200lbs while the trailer plate shows 3400lbs.

Very nice work! Great write up.

The plate on mine is painted over and I can't scrape it off. Glad to hear the 1101 has a higher rating, I'm putting a Geithner S788 shelter on mine and mounting tubes under it, making it longer on both ends for a camper build. It might get heavy.

Oh yeah 16 foot lumber in a 7 foot trailer wasnt a good idea. I didnt have a 16 foot trailer... It worked though.

Yes just temporaily Im not using it like that. I will drill all the way through and bolt through frame rail before i use it. It would probably be fine the way it is. I just want it as strong or stronger than factory. I just wanted to make sure tires didnt rub. There is still 2 inches inside wheel well.

I like what you've done!!

FYI, the rail you are talking about drilling up through is steel, not aluminum, and it's pretty thick... I think I'd just drill and tap it for two 1/2" bolts per side and call it good.

Y'all have to remember, these trailers are rated to haul their max payload off road, going as fast as a HMMWV can manage... As compared to a commercial trailer designed to be pulled down a road of some sort, by a road going vehicle, they are way overbuilt!

And you can toss the shocks, since the tires will squash more than the suspension will move with only a few thousand pounds in it. I put zip ties on the shock shafts, then beat mine pretty hard with about 2000lbs in it. Didn't hardly move the zip ties 1/2". Wouldn't surprise me if these axles had the same rubber as a normal 8k axle!

Good to know The shocks weigh a ton for these things. You are right That tube is thick. I havent done any more with it. It looks pretty good lowered to me. Way more usable.

I know this is a late reply but I just bought an M1102 and I want to consider this mod.

Q: The vertical sheet that the ends if the axle pass through (see pic #3), does all the material need to be removed?
It would be easier if only the axle slot needs to be cut out (and holes drilled).

Q: Without a plasma cutter, what is the best way to cut through that thick aluminum?

 

[drivebymashing]

I only notched it out so it can be reversed if you wanted to
I used a side grinder.

 

[djglover7]

The upper portion of the notch would have to be removed. To raise the axle.

What I was referring to was all the other material on either side of the notch.

Once this is done, there is no reversal.

 

[drivebymashing]

I left the extra material on sides.the factory holes are still there on side plates.
Post 67 or 68 shows the picture of side mount

 

[djglover7]

Sorry, I am getting two mods mixed up.

Did you ever get to the point of bolting to the steel frame?

Did you stay with the HMMWV wheels?

Forum,

I am getting ready to purchase wheel adapters to go from M1102 8x6.5 to GM 8x180mm.

Question I have is; what is the M1102 hub center ring diameter? I think it is supposed to be 126.1mm.
