Default My answer to STIFF suspension

To get more flex out of my HL I added Traxxas ball ends to each end of each leaf allowing the springs to rock side to side. This does require cutting the leafs, but it is worth it. I almost doubled the flex. I have tried the chino spring mod but this works better for me with less slop.

First, for measurement purposes attach the longest leaf to the main leaf. Then take metal cutters and cut the main spring the same length.

Second, make a 90 degree bend about 8mm back at each end.

Resulting in this.

Next drill about a 1/8" hole in each end and round off the square ends.

I wanted to use the stock HL screws that hold the springs on so I drilled the Traxxas balls out with a 3/16" drill. Screws that fit through the balls could be used but some type of shim or spacer would be needed in the springs mounts on the truck.

The finished springs.

Now remove the long second spring that was used for measuring and put whatever spring is desired. Mount them on the chassis. This may require a washer to shim between the ball end and spring mount or the mounts can be bent in to take out the side-side play.

Niiice

Real trucks have some sort of bushing in the leaf eyes, makes for better articulation. I might have to try this.

Thanks. I was just so tired of the crappy flex. I finally realized that it was not caused by the firm springs, but the inability for the springs to rotate side-side.

Exactly. Thinking about that is what led me to this.

You can also fine-tune the springs with this too: Spacing the rod-ends out further from the center will soften up the spring.

Nice mod, that should also make it easier to make up springs from scratch.

I wonder how this compares to a chinco mod which also addresses the twisting motion of a leaf

i wonder if anyone has tried it in 1:1, although probably not much need for it since the load is way more than on comparetivily on an rc. but there are composite leafs, i dont see why they couldnt put a ball end in each end.
