So we are not using the center diff at the center. Two center diffs act as front/rear diffs because pinion gears are easier to work with than bevel gears.
11.1V 3s turnigy lipos have moved the beast in the past.
We are doing our own aluminum frame and axle housings so mainly interested at strong knuckles, wheel axles and dogbones for the wheel axles.
AH, I thought you were looking for a complete RC axle. What you show in the picture we would consider a MOA axle. Each axle having its own motor and gearbox self contained.
The steering knuckles on the kyosho mad force kruiser ve may work. they are cast metal. the axle's driveshafts may also be usable for your goal.
the RC4WD
Bully Axle has all metal MOA axles. Again, the steering knuckles/stub axle/hex and driveshafts may be usable.
the very common and popular Axial brand crawlers have plastic axles housing....but there are metal upgrade steering knuckles available. If you used them then axial driveshafts, stub axles and hex's could be used. There are also axle wideners available for their trucks if you wanted to make it wider.
I think most 1/8 car or truck steering knuckles may have caster built in. But 1/10 or 1/8 scale rock crawler knuckles (or upgrade metal versions of them) may give you what you are looking for.
Axial wraith
Axial SCX10
Kyosho mad force
RC4wd
Look up those models plus steering knuckle and see what pics come up (google search) If you see one the shape/style you like you should be able to find a metal upgrade version of it. Then the stub axle and wheel hex for that model can be used, and maybe the axle's driveshaft as well.
