What Exactly about 37's makes everyone say sleeve and gusset
I have read lots on the forums regarding when moving to 37's it recommended to sleeve & gusset...
My question is I have a 2012 JKUR D44 and am considering 37 BFG KM2's
From what I have researched 37 KM2's weight are close to the same as 35 Trail Grapplers which many with 35 Trail Grapplers do not sleeve and gusset so my question is it the weight of the 37 or the diameter that makes everyone talk about reinforcing the axle with 37's...?
Seems to me a Rubicon with 37 KM2's would be no different than a Rubicon with 35 Trail Grapplers weight wise

The gusset/sleeve issue is not just a 37" tire issue. Weight is part of it but the tire diameter also adds to it I believe. However, you are talking about KM2's and their 37's are just slightly bigger than a Nitto 35" since they run so small. But, if you read the threads around here, gussets can help prevent C's from bending even with stock tires......yes stock tires..
If you are going to wheel your rig, they are worth the investment regardless of what tire size you get. Most people wil recommend them with 35's and up but they really are a good idea if you plan on dropping your stock jeep off rocks.
the biigest issue with 37's is with people running them on the dana 30's due to the weaker/smaller gear sets which will eventually fail (may take a while).

I've always heard it's a good idea to gusset for 35's and up (or even for heavy 33's); as the C's are a weak point in stock D30 and D44's
I'm not entirely so sure if sleeves would be neccesary, but good insurance either way - especially for moderate to heavy wheeling.
Happy looking axles are not happy axles

Weight.
Bent both the front and the rear axle housings so far. The front was gusseted and sleeved running heaving Toyo Open Country MT 37's. I can see it working with 37's and D44 that have gussets and sleeves as long you take it easy. Who knows but that's why...
