I had 3 of these as spares and in less than 3 hours of running, I managed to break all of them. I can't believe how brittle these TCX suspension arms (and hubs) are. I'm seriously disappointed. Before anyone says "stop hitting walls", yes you are right. But I've been running my RS4 Pro for 14 years and have not broken any suspension parts yet! Just as a data point, I used my RS4 Pro for the remainder of the day for another 3 hours with no broken pieces...

I know there's a supposed to be a HPI High Traction Suspension Arm Set 31420 that's a little "softer". But they are never in stock. So for all intents and purposes, they don't exist.

Any other after market ones out there?

The smokem chassis flexes more then the exotek, depending on what your looking for you can make the choice. I'l be running outside real soon so i'm not to sure just yet which will run better there. I have a bit of a fear of my battery flying out so my preference is the exotek untill smokem adds some retainers.

Use the 73506 arms. To me they seem a bit softer than the originals and are stronger. I see they are available online: http://hotbodiesonline.com/products/en/73506.html

The Tamiya short arms like the ones on the 416 & 417 also fit.

Do you have the part number and does this have the exact same geometry as the originals?
