Afraid you won't find those I believe they are a darker anodized blue than the standard Tamiya - 9444358 and probably not available separately.

42273 short dampers came standard on the TB04 PRO kit and TA06R kit from years ago.  The TB04 PRO manual shows the damper body, adjuster, and cap come together as a set as part number 19804765.

TRF Short Damper product page:  https://www.tamiyausa.com/shop/option-parts/rc-trf-short-damper-4pcs/

TB04 PRO (first version) product page:  https://www.tamiyausa.com/shop/110-4wd-shaft-drive-road-tb/rc-tb04-pro-chassis-kit/

TB04 PRO manual:  https://www.tamiya.com/english/rc/rcmanual/tb04pro_t.pdf

Manual page 30 damper cylinder/adjuster/cap part number:  19804765

Definitely hard to find, or special order at a minimum which will be pricey.

I was afraid of that.. so here is the situation.. I have enough parts (or so I thought) to build a few trf dampers.. touring and m chassis.  So I figure rather than buy a whole kit, I would just build a set for my m chassis.  

I was that Tamiya USA was discounting these, which are the HL version of the 42273... so I thought why not.. it would only be $20.. WRONG lol.

I contacted Tamiya USA and inquired if these used the same top cap and bottom cap as the 54000 M chassis.. they said it did.  Well as it turns out

  • Top Cap is low profile arg!
  • Bottom Cap is normal

So I emailed them back to see if they have a solution..

Then I scoured the net trying to see if the low profile blue caps or even black caps are available separately.. which appears they are NOT

So I am left with 3 options

  1. Tamiya USA comes up with a customer service solution since they gave me incorrect info
  2. Buy the 54878 TRF SS BB upgrade for my 419x SS BB and use the black caps from those
  3. Buy a set of 42273 and call it a day

54868 upgrade your dampers for the 419x (it makes them all blue and increases the movement range).

then use the Black caps on your shocks
