The black (dark grey) TC ones are the flourine coated shocks which are very smooth like the TRF shocks but you need to use pre-load spacers.

Default forgetting the colour........

forgetting the colour for a moment, will the shocks just bolt on to the xray without any faffing about? maybe still using the xray ball joint shock tops but everything else as standard?

You have two options,

Fit the TRF shocke with the Tamiya ball studs top & bottom or as I do,

Use AE top mounts (p/no 31250 available from A Main Hobbies) on the Tamiya top mount & use the Xray base...simple

+1! I use option 1 for my xray 2009 and works great.

going back to colour, Tamiya has a TRF damper set that is anodized black, part number is TA-84008. This is what i use and you could see the picture at the link below:

Hey craig what do you mean by * Trim 1-1.5mm off the piston to get the correct length

To make them work properly on the xray you need to use the xray shock top and bottoms, you can either take them off your plastic shocks or get 2 x 308302.

In order to get everything working right together you need to make a couple mods
* Drill out the tammy cap to take the xray shock top
* Trim 1-1.5mm off the piston to get the correct length

* Sand down the lip on the underside of the xray cap that retains the bladder to about 0.5mm to prevent it cutting the tammy bladder

There's not a lot wrong with the xray shocks but I definitely prefer my car on the tamiyas.

at the end of the shaft he means were thread is make it 1-1.5mm shorter so when u put xray bottom on. it jams up when u tighten up to correct length if not shortened

I have had a few runs now with the TRF shocks, and am having trouble getting them to grip as the XRAY ones did. Lateral bite doesnt seem to be right with them, I am wondering what oils/pistons others are using. I have tried the kit 350 cst and other 450cst oil, but the damping seems alot stiffer and less forgiving of bumpy surfaces.
The car seems jittery and just bouncing over the bumps instead of absorbing them as it did with the same weight oil and springs on the xray shocks
By my reckoning, side by side with the XRAY shock pistons, the TRF pistons have smaller holes.
Looking into shock damping characteristics, "pack" and fluid dynamics my head is swimming with all the factors.
I have been thinking about using the other pistons in the kit, trying the larger hole pistons and thicker fluid to stop the shock packing up so much when high speed damping for bumps.
Has anyone got any experience with different oil weights or effects of different piston holes?
I can only assume this is why alot of people go to the TRF shocks, then give up on them, as the common complaint of XRAY drivers is that the TRF shocks dont give as much grip.

Which pistons you use? 3hole, with 450-500wt should be the ticket to start with... as that's pretty much the base setting most tamiya guys use..

I think you should really buy the Xray kit, build the shocks and then make a decision. In my opinion, they are a very well made shock and you really need no upgrade. If you don't like the adjusting pistons, they come with fixed pistons as well.

I switch to TRF on my 411 and they work great. Regarding the stiff issue. I found an error in the manual included with my trf shock. But they have correct it in the 417 manual. For the bottom o-ring the manual I got is first put the o-ring, then the white plastic spacer, last the big white spacer. I notice it is different than the other TRF shocks or 3racing shocks I build before (spacer > O-ring > large spacer). But I am stupid enough to through they may change the design so I follow the instruction..... The shocks are very inconsistance... After I test it for 2-3 runs I took the shocks apart. Put the spacer in the way I always build them. (spacer > O-ring > large spacer) And it works perfect and much smoother.

I bought the shocks aftermarket, and the manual says oring, small spacer, then large spacer. What I have noticed is a large amount of "stiction" or static friction in this configuration, even after greasing the oring. Takes alot of effort to get the shock moving which I think is the problem I am experiencing on the track.
I think you are onto something here mate, I will definitly try small spacer-oring-large spacer and see if it improves the damping characteristics.
I will let you know, but I have looked at the TRF 417 manual and it says to put it in the configuration you are talking about, small fat spacer first, then oring, then large flat white spacer. I hope this fixes the issue as these shocks are so sweet and easy to build.
