Wltoys 104001 104002 104027 rear hub upgrade Part No. 1862

Made these temporarily until I got my metal upgrades, turns out to be stronger than the original for extreme off-road racing on a clapped-out track. There are two versions, the OEM replica and the extreme duty modified one, either works great with quality PETG like kingroon, eryone, california filament, and geetech. I would not bother with Zytech junk. I don't know why the 7 dollar rolls are just so much better but here we are.
