GC3A Rod End Slop Fixed

So, those of you that have a GC3A and run the stock links and Duratrax rod ends, know that the ID of the ball is slightly larger than the 3mm screw that runs through them. This has been a sore subject with this chassis (about the only issue I've found so far). I didnt like the slop and tried to find a way to fix it. Well, I have. It's cheap, simple and will bolt up to the stock setup.

If you are running the stock links with a shorter shock (~3.5"), you know that your WB comes up just a tad short. This mod will help with that also.

You'll need two packs of these:

These rod ends are 1.1mm longer than the stock rod end and the shaft is 0.8mm smaller in diameter of the stock rod end. The stock grub screw will thread right into these rod ends. I have not run the truck yet with these rod ends, but I am pretty confident that they will hold up about as well as the duratrax rod ends.


You are going to install them on the front and rear uppers and lowers at the chassis side.

Since the traxxas ball ends are slightly wider, you have two options here. Either open up the slots in the skid, or grind off the lip of the ball ends. I chose to open up the skid. I did so with a small high speed cutter on my dremmel. Here is the result:

(yes, I also used a new skid)

Here is the job finished:

This truck is dead on 12.5" WB and now has no noticeable rod end slop! "thumbsup"

I think the traxxas hexagonal rod ends are the same length but stronger.

Why not just swap to lunsfords instead?

Also can't you just swap traxxas balls into the Duratrax rod ends?

The hexagonal ends are quite a bit longer than even these. The traxxas balls are too small for the Duratrax ends...you end up with the same slop. I was looking for a cheap and easy way to get rid of the slop. "thumbsup"
