ST Racing Concepts 12mm Aluminum Hex Adapters for Traxxas Slash 4x4 (Blue) (4)

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.
