Question Differences/benefits of the "hard-anodized PTFE-Coated" shocks vs the standard ones?

I'm looking to order some TRX-4 shocks (not for my TRX-4 but for an SCX10 ) and I noticed that Traxxas offers both the 8260 ("Silver aluminum") shocks and the 8260X, which are Hard-Anodized PTFE-Coated.

What are the benefits of the latter? They are only bout $15 (Canadian) difference per pair.

The PFTE coated shocks will have smoother movement of the piston inside the shock and the hard anodizing will resist scratches better than regular anodizing.

Will that make an actual difference for the extra cost? Probably not.

Thanks for the explanation! I've been running my TRX-4 with regular shocks for nearly a year and they look and perform very nicely - for the small difference in cost, I may just get these PFTE coated ones, put them on my TRX-4 and put my old shocks into the SCX10

Agreed, racing buggies the hard anodizing definitely makes a difference.
They should last longer and be more consistent damping.

I have the titanium nitride shafts in one of my trx4s. There’s not a noticeable difference in smoothness but they certainly didn’t hurt and have held up well. No visible scratches and still butter smooth, that trx4 gets pushed too as it’s the most capable of my rigs. Have only had them in since December.

also have a set of the 8260x shocks sitting around waiting to go into a new build eventually, haven’t fondled them yet.

Pretty sure Ti Nitride is the same stuff they put on mountain bike fork(think Fox forks with the bronze colored tubes) and it is meant to reduce “stiction” on the sliding components. Mtb forks will stick a little under light load so its supposed to help on small bump compliance.

That sounds about right, the shaft coating is intended to improve scratch resistance and increase life. One could argue that a shaft that stays in better shape longer, overall performs better but that's splitting hairs I guess. I thought long and hard about those PTFE shock bodies and gold shafts, but am happy enough with the kit shocks.

TiNi shafts should have a little less stiction and definitely last longer especially with lots of dirt and grit.

THose new shocks look great!

No, MTB forks (good ones are aluminum alloy legs) and are hard anodized or Fox uses Kashima coating, which after double checking is a propietary hard anodizing process. Is one process better than the other? Not sure, but Fox loves to charge out the yingyang for it lol. Yes, it reduces stiction, friction and wear.


KASHIMA-COAT.COM What is KASHIMA COAT?
"Kashima Coat is a proprietary hard anodizing processing that Miyaki Company of Japan has invented, lubricating molybdenum disulfide deposited via electrical induction into the billions of micro-pores on the surface of hard-anodized aluminum for better lubrication and less abrasion and wear."

Finally got around to building these and I have to say they feel great. gts shocks have been smooth in general, and perhaps itís because this set is new, but Iím impressed. If this feel holds up then it could be worth the extra $10 a set.
