These are for the portal axles only. Won’t fit the straight axle on the Early Ford Bronco SCX10 III. Would have been nice to know before buying. Samix website doesn’t even mention this.

These don’t come with any grub screws, just open holes that you can’t even used. Cheap company can’t even provide 4 grub screws...

Honestly just bought them to go along with the rest of my Samix parts. Couldn't say I for sure noticed any improvement but whatever gains I can get I'll take plus they look great, love that they didn't just go full brass. Nothing wrong with full brass but personally it just sticks out too much. Machined to perfection

Work great, no issues, what else to say...? Having a set screw is a huge upgrade alone- but add the extra 2mm and brass, and these are worth every penny.

Outstanding product. Worked great for the scx10 iii with stock wheels

What reviewers say

Reviewers are split. Two reviewers rated it 1/5, reporting that these adapters fit only the portal axles and not the straight axle on the Early Ford Bronco SCX10 III, and that they arrived without grub screws, leaving open holes. Three reviewers rated it 4 to 5/5, praising the fit with stock wheels, the set screw, the brass construction and the finish, though one noted no clearly noticeable performance gain. The fitment and missing hardware complaints are the recurring problems raised in the lower ratings.

  • + Works with stock wheels
  • + Set screw included
  • + Brass construction
  • + Good machining and appearance
  • − Does not fit straight axle
  • − Grub screws missing
  • − Fitment info not on website
  • − No noticeable performance gain reported
