So the question is, how much weight can a Tamiya semi axle handle? How much torque can the differential gears take? Are there any hardened gear set upgrades available? I don't know what my tractor will weigh, when it's complete, but I want it as heavy as possible. 20 to 30 pounds? Will the axles survive? I know some of you guys haul heavy loads on trucks, but that's not running larger ag tires, with better traction.

Dang Nate you are tuff man you cant even tell they they were not semi axles.. Anyways my globe liner hay hauler weights in at with the load 42 pounds and has not problem with gears never has..

Now one of my 2.2 rock crawlers weights 19 pounds and has a holmes puller motor in it witch has crazy power and tork is unreal no one has power like this in a semi. I run 11.1 lipo and mash on the throttle and I go threw one set of gears a season. So what I am saying the TLT gears are semi gears the pinon always go first.. Now you can get harden pinons and center sections from RC4WD and they help a ton if you run them gears in a semi you will never have a issue and for that fact you will never have a issue with the stock ones. Greg had dirt pushers D9 at 110 pounds one his lowboy and it did not hurt a thing..
