About this part

This is a set of optional ST Racing Concepts CNC Machined Aluminum Hex Adapters, and are intended for use with the Traxxas Slash 4x4. These 12mm Hex adapters securely mount on your Slash 4x4 tires and wheels with no chance of the adapters being rounded off under heavy torque and power loads. Set screws on the hex adapters securely hold them in place on the stock axles (may not be compatible with aftermarket axles). These parts are CNC machined from high quality aluminum and anodized blue, for durability and good looks.

Absolute must have, especially for a Traxxas Hoss. I love my Traxxas Hoss that I also bought through amain, but the stock wheel hubs just shredded, and two of them completely bored out and bent the two metal pins. And all of this happened in the span of 15 minutes of driving it around the yard/street, so just average use. Certainly no jumps or tumbles. I have seen other Hoss trucks do perfectly well for a while and eventually it becomes one of the first things to upgrade, but I recommend adding it in as soon as you can, because stripping out the stock plastic hubs can also tear up the inner wheel. Ever since I installed these and have had at least a dozen battery runs of both grass/dirt and pavement use, they've held up perfectly well. I've even had them apart just recently to check em out and they're still just as shiny blue as when I installed them.

These are great when you do not want your hexes to be stripped! However, once I got MIP X-Duty for slash 4x4 I couldn't use them anymore. I just used these on my nitro 4tec instead. They are good quality!

Far better than stock plastic ones. Installed easily and no issues with them. I would probably put these on the "must-have" list for Slash 4x4 owners.

What reviewers say

Three verified owners rated these aluminum 12mm hex adapters 5/5 and all say they are a clear improvement over stock plastic hubs. One reviewer reports the stock hubs stripped and bored out within about 15 minutes of average yard and street driving, and says the adapters have held up over many battery runs on grass and dirt. Another reviewer notes they fit well on a Traxxas Hoss, and a second reports easy installation with no issues. One reviewer found the adapters no longer fit after switching to MIP X-Duty axles on a Slash 4x4, and used them on a nitro 4tec instead. Reviews are few and short, so the evidence base is limited.

  • + Stronger than stock plastic hubs
  • + Resists stripping and hex damage
  • + Easy installation
  • + Good build quality
  • − Incompatible with MIP X-Duty axles per one reviewer
