Wonder why AE, and TL still do not use a pure Silicone o-ring like on the TRF shocks. My TRF's seal does not swell up and keeps the oil fresh for much longer.

I dunno, but I know alot of touring car guys use the TRF shocks on pretty much any of the touring cars. I haven't had a problem with the shocks on my TC5 but I have felt the smoothness of the TRF shocks, they are definately the nicest.

Are the o-rings the same? Whats TRF?

TRF=Tamiya Racing Factory. No, the orings are not. The TRF's are pure silicon, where as the others are a mix of silicon and other compounds.

Who cares if they're made of different materials, the real question is would they fit?

Wouldn't doubt you could buy a box of about 50 of the exact same thing from McMaster-Carr for a fraction of the price, too.

maybe...i dunno. As far as whether or not they will fit, only way to tell is to buy some and see. Also, it's more then just the o-rings on the TRF shocks that make them so smooth, i think the shock bodies are teflon coated on the inside as well.

Thanks guy. I have an open account at McMaster Carr. Thats were I bought my lead for my LIPO.

I have had some A/E shocks that are not machined correctly and the clip pops out no matter what you do. Most of the team guys tell me when one ejects a clip, they change out that shock body.

I give it two tries since I pay for mine, lol, but if they pop out twice, I know I built them right, new shock body.



I mostly hate sitting there wittling down the edges of the spacers, etc. But, something I find alot of racers don't know is that the edges of all the spacers are different on each end. One end is sharp, one is rounded. Always install rounded edge first. Cuts less seals that way, .

I have bought a bag of 100 silicone orange o-rings in the specified 1/8 x 1/16 size from McMaster Carr --it was only like $5 for the bag. The problem is, they are very slightly larger with a tighter ID--they cause quite a bit more stiction on 1/8" Associated and Losi shafts. You can tell just by looking at them --its only a fraction larger but its enough to affect shock movement. Just warning others.

I'm almost relieved to hear that - I had issues with a couple AE shock clips. After wasting a lot of time, I ended up reaming out the bottom of the shock with a drill bit (slightly) and that seemed to fix it.

I have some on road TRF shocks and they are truly amazing. They might be so smooth because they only use 1 'O' ring and not 2. I considered installing the 'O' rings in my AE shocks and I recall comparing the two and deciding that they would not fit. But, I cant remember if they were too big or what I thought the problem would be - its been a while.

There is a place in Arizona called State Seal that makes o-rings & seals of just about any size & flavor. Dont know the number but a friend of mine bought a bag of them before.

The Tamiya shocks use exotic hard coatings on the shock bodies and shafts, and even the pistons, plastic guides, are made of some strange slippery type of plastic. I'm not sure if its the flourine stuff they like to put on ball studs, but after using them in both onroad and offroad, I can say the are the finest engineered shocks you can buy.
Honetly I dont think the Tamiya silicone o-rings will fit. They only use 1 per body, and they are larger than the normal o-ring.
Doesn't General silicones still make R/C stuff? They use to make pure silicone o-rings for all the major shocks as an upgrade.

you can ream out the bottom of the shock where the o-rings go in with a .256 reamer, go slow. it will remove enough material so when the o-rings swell up they are perfect. however the o-rings may leak just a little until they do swell up and if you go too fast with the reamer, ie a drill, all bets are off because you probably ruined the shock bodies.

These will work, but doesnt say what they are made out of. According to Tower AE seals are 1/8 x 1/4, or 3mm x 6mm, so it shouldnt be hard to find a pure silicone seal (if the size is correct)

Those are the MIP seals--Most people I have seen don't really like them. I don't think they are silicone--and they tend to have more stiction than the stock 0-rings.

The tamiya o-rings I am familiar with are the metric orange silicone ones we use in the 501x WCE shocks--are you guys talking about a different Tamiya o-ring?

Did anyone ever try fitting the blue Traxxas X-ring seals? Since they have an X-cross section they should seal quite well while still being very low drag. I don't know, however if the Traxxas shafts are SAE or metric.
