HPI Savage TCS Flux 5T (XL Axle & HD 23mm Hex)

When I started to upgrade the suspension parts I noticed the proline 23mm hex were not holding up. The 2 rear hex are stripped out.
I went to ebay and bought a different style 23mm hex with more side wall support. Unfortunately that did not work either because now the pin broke. I dont know if you can notice the aluminum bulges out a little where the pin goes (left hex). It looks like the side where is starting to give out. That might of happened when the pin snapped. |
The next mod is the wide HPI Savage XL axles. I wanted the truck to be a little bit wider and I needed a little more space to use another 23mm hex. And the last reason why I need the extra width is because of the LST shock conversion I am doing. With the wheels a little further out the tires will not hit the shocks at full turn.
Please note: there are only 2 axles cups that would work for the Savage Flux because it uses a larger Dog bone that has a 11mm ball (the stock Flux and XL wide). All the other Savage has a 9mm or smaller dog bone ball. Here is a picture of the XL axles next to the stock Flux:

The next thing I will be doing is to machine a spacer that goes over the threaded part of the axle. I am hoping this spacer with help distribute the load on to the shaft more evenly and reduce the chance of brakeage.![]() ![]() This picture show you the hex without the spacer
And in this picture you can see that space with full contact to the 23mm hex. So in theory I hope it would make it stronger. Here is a close up of the spacers, made from of 6061 aluminum rods. |
