Default leaky shocks

I'm fed up with my shocks. I'm running a FT TC4 with the stock shocks, and they leak even though I add green slime onto the o-rings. I applied a generous amount of green slime and it still leaks. It must be the design of the shocks where the oil sits on the o rings and causes the green slime to break up its density. What are the LEAST leaky shocks or shocks that never leak? I'm willing to spend more than $80 just so that I don't have to deal with this nuisance.

I found some on ebay but are from Hong Kong. Are these counterfeited or is this ok?

my ft tc4 has sat on my shelf for a year and hasnt leaked or gotten air in it.

ran it for a month like that before storing too.



have you tried changing the orings or checking for an enlarged opening from a bent shaft?

I had leaky shocks before on my HB car. A simple fix I tried was to use a cartridge washer before the o-ring. If the shock binds a little take out the washer and sand it down until the shock stroke is smooth

HPI103409 I use them on my TCX with the washer sanded down and on my blitz ese. I am unsure If it will fit on your shock shaft assuming the size is different.

The TC4 came with the older shocks with the foam compensator and no bladder. These are very easy to overfill, and if you overfill them then the oil will come out the easiest way - through the seal.

If you want to stick with the foam compensator, make sure it is well soaked with oil, and when you fill the shock and assemble it for the first time, check that the damper action is smooth all the way through its travel and doesn't stiffen up near full compression. If it stiffens up, there is too much oil. If it squeaks, there is too little oil.

The optional bladder caps make the shock a lot easier to build and basically the same as the new V2 shocks on the TC6. No need for TRF shocks.

The TC4 shocks are rubbish, the version 3 associated shocks might be ok but kyosho and TRF shocks are the best shocks available. TRF shocks are cheap and readily available may as well use them.

Or use 2 o-rings instead of a damper spacer and 1 o-ring.
Also check the pistonshaftguide for to much play, same on the piston.

and do I remove the foam compensator when installing the bladder caps?

just buy the vcs2 upgrade kit. then you get the aluminum caps and modern bladder configuration. im gonna try this on my FT NTC3 shocks. the bodies look identical so i dont see why it wouldnt work.
