Awe man and with the stuff you haul that's got to be a pain in the *** good thing you don't have to back into places like we have in Michigan, my company I worked for did demo of abandoned houses in Detroit so you have to back into soft dirt lockers and inner lock is needed for that

Re: locked differentials
 

I was tossing ideas around about how I could lock the KH diff's. Here's where the duhh moment hit me. I have a pair of Hilux 4x4 axles collecting dust so I began to operate on the front locked diff. Tamiya uses the same carrier for their axles! I simply transplanted the carrier to the KH differential. It locks the shaft with a grub screw so I have to make a flat side for the grub to grad the shaft in the carrier. It is completely reversible without any use of glue or welds. Just thought I would share this for anyone looking for ideas.

DAM, I was going to mention the gear trick, but saw someone else here already beat me to it.

I just remembered another limited-slip option a lot of 1/10 scale crawlers run where Open doesn't work, but you don't want turning radius of Spool.

Silly Putty.
Clean the carrier and gears. Figure out how many eggs you need to pack diff. To loosen the amount of lock, add silicone shock oil. Work in a couple drops of oil to the putty, assemble enough to test it. Go slow adding oil, or you'll have to add more putty to thicken again.
