Upgrading the Clod

A Tamiya Clodbuster is a fantastic monster truck, but it’s handling leaves something to be desired. It tumbles over at the slightest turn and the stock all wheel steering setup mostly results in the back steering more than the front. To mitigate the tumbling I decided to install a 4 link suspension kit and ended up buying a CPE 4-Clod set.

This set by itself can’t be mounted on a stock Clodbuster chassis, but CPE’s website clearly states what you need to completely assemble the set. The bag in the top left of the picture are the additionally required parts and the other object is a program card for the brushless speed controllers I have mounted in the Clodbuster chassis to replace the original brushed ESC.

There were no instructions including in the set, so the first thing to do is figure out how to attach the links to the chassis. Turns out it’s not that hard. First thing to do is figure out what’s needed to attach the link to the chassis.

The bolts and nuts are not included. I used standard M3 bolts and nuts.

After a little while I had the lower links attached to the chassis like this.

On the inside of the chassis sits a little metal plate where the stock ball ends were screwed into. This plate has M3 screw holes in it, so the bolts drive into it nicely and make sure the links are held tightly in place.

The upper links are slightly more difficult to put and keep in place.

Here it’s necessary to screw the nuts on the bolts to keep it in place, but there is very little room to do so. But as you can see I made it and now all links are securely attached to the chassis.

After that I mounted the stock shocks to the upper links using the clamps from one of the additional parts bags.

The bolts that came with these clamps were American M3 hex bolts and those are not compatible with standard European M3 hex drivers, so I replaced those with the same M3 bolts I was using for mounting the links.

The upper links can then be attached to the C-hub on the Clodbuster axle. The lower links, however, cannot. For the lower links a hole has to be made in each C-hub to mirror the holes that are already there. After a while it looked like this.

With both axles mounted it turned out that the stock steering link is a bit too short for this suspension setup.

But this problem is solved by mounting a larger servo horn at a 45 degree angle. For now the end result looks like this.
