Heres a list of what makes a difference in no specific order. Not in the list is the case itself, I swear they get tweaked after a lot of hours or wasting a set of gears. Seems like they last longer when its a newer, unmolested case without past failures.
Any rebuilder that does a decent job is going to add life but here are some upgrades that seemed to make a difference:
1. cryo gears
2. steel tower
3. bigger/more rigid aftermarket topcap
4. aftermarket bearings
5. 7/16 stud conversion on topcap (I think this helped a lot and cost next to nothing)
Whatever happened to the OSO guy that was going to start manufacturing their own XR gears out of some precious hardened space metal? Like 3 people have said this over the last 10 years but it never pulls through...

I can add some useless knowledge after having a few sets. There are a lot of things that impact the ability of cryo to extend life. If you throw gears in a build with bad assembly tolerances, and without stuff to make the case and tower more rigid (like 1-5), you wont see results. ...and I think that has happened to me. But my understanding cryo treating is like an egg shell, it only goes several microns deep. So it helps with wear, but not with shock. If you were to do deep cryo, it would make the teeth more brittle which is what you DONT want.

I would also add a redesigned upper drive shaft. They are usually the reason the gears get toasted. The original bearing is a joke and the shafts start to flex and then snap at the oil hole. AADS has redesigned it and put in a larger bearing. AADS has bins filled with hundreds of broken shafts and all look exactly the same. His don't break.
