get the lower shock cartridge for the rb5 and use them with the right bushing in between the o-rings. that is a common problem with that model zx5 the new SP has the rb5 cartridges already

I never had issues with the ZX5 shocks. Still running the kit shocks with the original o-rings. I will admit I am running the x-groove o-rings though. ORG03X. I also use green slime on the o-rings when I build them. I would get the clear ones and not the orange ones. We have noticed the orange ones swell over time. The work great and are durable but after about 6 months they need to be replaced. I would try this before you spend the money on all new cartridges.

You might want to try some new shafts as well. My original shocks were great for a long time, but when they did start leaking, new "X-rings" (the clear ones) didn't help a bit.

I never really noticed it, but when I compared the new shafts in the conversion set to the shafts on my car...mine were pretty thrashed by comparison. They were very worn and rough where the o-rings ride.

I got my ZX-5 used and got the RB5 cartridges, but 2 still leaked, I found that the top oring (under the cap) had flattened out and it was leaking from there as well, just one more thing to check.

Good point Joe. the o-rings will only seal to a smooth surface. If your shafts are scratched it will let oil through and tear up your o-rings all at the same time.

so try the orange o ring first? or the clear one? what is the part number of each.


The shaft seem to be in good shape. the buggy is in pretty good shape and run only at socal.

Thanks

Use the clear ones. ORG03X

The orange ones are ORG03XR in case you wanted to know.

Thanks.

I went to Ultimate, some guy there gave me the complete shock rebuilt kit only good for two shocks. Will have to go there again later to get the o ring kit. All 4 of my shocks leak.

I run at socal, Anywhere near there that carries Kyosho parts?

Speedtechrc is located up in Walnut area (57 and the 60) I am drawing a blank on anyone else that carries parts. Speed tech just got a huge shipment in so they should have everything you are looking for.

Speed tech has moved to San Gabriel but he does usualy have what you need for your ZX-5 or RB-5. And yes he did get a big shipment in but you better hurry because the Kayosho stuff moves fast.

To save myself from driving around town at $3.70 a gallon to find the ORG03X, I bought a few ORG03x on line.

I have 3 extra packs I can part with if any of you need some. $8 each+ $1 shipping. If you get all 3, shipping is $1. There is 8 o-rings in each pack.
