Tekno RC Steel Ti-Nitride X-Long Rear Shock Shafts (2)

I strongly recommend these TiNi Shock shafts if you ever bent one of your TEKNO stock shock shafts. It is a bit more expensive than the stock one but it is much stronger and smoother.
You need to have the clamp tool to make sure you do not scratch these when you install them.

So these are supposed to make the already super smooth Tekno shocks even better, if that's even possible and help the shafts stay smooth longer... Because Ive always been a sucker for buying every option/tuning/upgrade part that I can find for every new kit I get, I ordered a full set of these upgraded shafts plus the delrin shaft guides to my ET48.3 when I built it. (Plus every other option part AMain had haha) While I highly doubt I can tell a difference while driving, the Tekno shocks are easily the smoothest and leak free shocks Ive built. Just make sure to regularly check and replace especially the rear shock boots as they tear easily and the dirt will speed up the wearing of the shock shaft coating which has started to show some wear on my rears after a couple of years. I've since added them on all 4 of my 1/8 Tekno rigs, the ET48.3, SCT410.3, EB48.4 and EB48 2.0, plus the smaller versions for my EB410.2 and ET410.2. A lot of money in shock shafts, but now I have all the unused stock shafts as backups if I need a replacement in a pinch.
