SH Z-Car ZMXB-8 1/8 Buggy - Perfect for conversion?

[Shark413]

Early I mentioned that the shock valve on the stock Z-Car didn't look very effective, because it had holes in it. I have been using shock valves in my Kyosho and Revo PE for a while and decided to mod the Z-Car shocks to incorparate a true valve. I took some Traxxas variable damping valves and added them to the stock Z-Car shocks. The Traxxas valves are solid and block most of the oil flow for true valve action. The small screw used for the stock valve keeps the valve flap from rotating away from the holes. I had to drill out the uncovered hole to adjust the main flow rate (since the two other holes are now covered I needed to increase the main flow) I started by drilling it to 2mm. I can now definetly feel the valve action on the rebound stroke. I like to have more compression damping, and a faster rebound damping, with no valve the damping is basically the same both ways, with a true valve you can adjust the compression damping to suit your needs. As soon as I can find some stiffer springs I will test it out on the track.


Stock Z-Car shock pistons with Traxxas variable valve added. You can see the stock Z-Car valve with holes in it.


Valve, stop screw and a new 2mm hole.




Hard to see but I am checking the valve action with a small pin. Valve open.


Valve closed.
