Not recommended. The fitment of the pivot points to the C-hubs caster blocks were too tight. Modification may be required to fit. Recommend using Traxxas 7737X instead.
got a gen 1 x maxx 6s with 8s conversion and they fit good didnt have to trim
The issues with these axles carriers seems to be fixed as these were a perfect fit on my Xmaxx. Amazing stuff from RPM as always.
I’m a big fan of RPM products, but I’m absolutely shocked that they’ve done nothing about the rampant issues with these knuckles, particularly with the pins coming out. It’s shameful.
These carriers have such a bad reputation and I am not sure why. Slight filing was needed to ensure the steering was nice and smooth, other than that they are great.
Reviewers are split on fit and quality. Two reviewers report good fitment on a Gen 1 X-Maxx, one of them after a 6S to 8S conversion, and one says the earlier issues appear resolved. One reviewer found the pivot points too tight on the C-hubs and suggested a Traxxas 7737X alternative. Another criticised recurring problems with the knuckles, particularly pins coming out, and said the manufacturer had not addressed them. A fourth reviewer noted slight filing was needed for smooth steering but otherwise rated the product highly. Overall, reviewers agree that some fitting adjustment can be needed, with disagreement over whether the reported pin and fit issues are still present.
- + Good fit on Gen 1 X-Maxx
