The best improvement I saw was having the gears heat treated at Tom's Differentials. That more than doubled the pinion life. Those small 6 tooth pinions will crack at the base of impact. Tom's heat treating allowed the teeth to bend before coming to pieces. Gear life was about 100 runs after heat treating. 3550 lbs with a stick.

Another big improvement I found was using a solid pinion spacer over a compression sleeve.

I'm sure the REM polishing, cryo treatment and some of the coatings available now would be beneficial.
