RC Model Hop-ups 12mm Hex Wheel Hubs 7.0mm&5.5mm Thick for Traxxas 1/10 2WD Rustler,Slash,Stampede,Nitro Slash-Replaces Part 1654 3654(4pcs)

They fit great but the set screw is super cheap and soft

About these because I change my tires on my RCs all the time got tired of my hex getting stuck in my tire and dropping the PIN he's really helped tremendously.

Much more durable than stock they don't strip out

These caused my Rustler front to rub against the bearing so I had to switch back to the stock plastic ones. The back were ok though.

Works great for 2wd stampede. Even came with spare pins.

Good

These move on the axles and on the front they slide in so tight that it interferes with the tire rolling free. Very upset.

Front hexes for 2WD Traxxas Rustler are machined incorrectly. The groove for the pin is too deep and will cause your front wheels to bind when tightened.Front Hexes are also incorrect thickness. The stock plastic ones measure on at 7.8mm (almost 8mm) these are 7mm which makes them a bit too thin and causes issues with some rims with thinner plastics at the hub.If you receive ones that look like the picture with a shiny machined circle around the grub screw then those appear to be fine. If you get solid red with no machining/beveling around the grub screw those are machined incorrectly.I wish I could give negative stars as this cause me a bit of headache and now I have to go out of my way to return this for something that should have been cause in quality control.
