I just refreshed my granite with Mojave Fronts in front and Notorious fronts in the rear. Everything fit well and if I'm reading the thread right, the Notorious shock is the same as the kraton that people commonly use (including same spring?).

I'm curious though - do people change fluids or springs generally, or just drop those in. Because it seems like the rear/Notorious is WAY more damped than the front Mojaves. Fronts feel similar to stock, but rear end is super damp. It feels like it also has a stiffer spring - but that could be the damping making it feel that way. Also both ends have pretty much no droop/sag. I can't remember if stock did, but seems like you'd want a bit?
I drop it and it lands nice and doesn't bounce and doesn't chassis slap until dropped from about 5-6ft. So maybe it's all good? Hopefully I'll be able to get out tomorrow and give it a test drive, but just curious.

I updated the shock-sheet.

But I guess, it's not complete.
I took the part numbers directly from Arrma and from the latest model (but compared them to the older ones).
JennysRC sometimes has other part numbers which definitely exists.
It's a bit confusing for me.

However, I hope the new list is helpful for you.
Why are the Typhon 3S springs stiffer than the Typhon 6S springs?

Typhon 6S:
- Front: 70 mm x 75.5gf/mm
- Rear: 84mm x 56.6gf/mm

Typhon 3S:
- Front: 70mm x 1.0N/mm (=102gf/mm)
- Rear: 80mm x 0.84N/mm (=85.7gf/mm)

As the 6S is a heavier car, I would expect the springs to be stiffer, not softer? Am I missing something here, or did I mess up the gf/mm calculation?

If you have a V1 or V2 Talion best bet is V3 or V4 Kraton shocks. Outcast/Notorious shocks are the same as the Kraton but will come with thicker oil.
The V1 and V2 Talion are much closer in design to the Kraton than they are to the V3 and V4 Talion.

I was too lazy to read through this entire thread initially and got the notorious ones, only finding this now. Can confirm - they are crazy damp. I don't have the kraton's to compare to but compared to the stock Mojave 6s ones in front it's a whole different world.

Everything I can find seems to say they are all 1000cst but that can't be right. Unless one has small holes and another has big holes. Anyway what did you put in the back? I have the yellow springs arriving today and will change things up.... I have some 80 I was thinking of trying. I also have extra disks with different holes that came with my fireteam. I don't really know the difference between thicker oil or smaller holes - they seem like they'd act similarly.

yeah mine feels the same way as I have the same shocks that you have in my Granite. Going to order the springs like you did and see how that goes. I actually prefer the dampening in the rear and want to match that in the front. Mojave is 550cst.

Stock notorious is 1000cst like you said. The Talion actually takes 2000cst. Looking at the manuals seems they all use the same shock piston AR330339

Great info - where did you get that from? It definitely makes sense of out of what I was seeing.

So I just put on the springs and put 40W (~500cst) on the notorious ones in the rear and now they are nicely matched. A good bit more damped than stock, and feels similarly sprung. A tiny bit of droop, vs being tightly sprung up at max extension with the springs that came on them. I'd imagine 1000cst gives you more resistance against bottoming out on big jumps and against body roll but tradeoff suspension action at high speed bumpy travel. That's what I noticed most - the granite was bouncing around a lot more when I was ripping over bumpy terrain... so probably just a matter of what you want to do with it.

Thanks all for the great info!

Your welcome. I actually pulled that image from the manual.

Whenever I am checking to see if a part will fit on a vehicle or which arrma vehicle I go to the arrma main website. Type in the part # and scroll down to the bottom of the page and it will tell you which vehicle it will work for.

If it ain't broke, you're doing it wrong.

I posted that like 3 years ago and a lot has changed on these cars. Even the shocks themselves are different in the V5 versions compared to the V3-V4 cars.

Yes, 3s springs are stiffer than Typhon 6s springs. The 6s Typhon springs are tuned for a racing setup. I've mentioned this in many threads on 3s shock upgrades. While the Typhon 6s shocks are the closest match in length to 3s vehicles, the light springs are far from ideal for jumping/bashing. Many people are opting for the Mojave front shocks/Kraton front shocks for their 3s. The springs that come with the Mojave/Kraton front shocks are much stiffer and are a closer match to 3s springs.

Thanks for the confirmation, good to clear up the confusion.

I have two Typhon 3s rigs for track racing on a local track, and one came with the ZD racing springs when I bought it used. They are too long, springs are too stiff (especially rear) and two of them are leaking like crazy. I was thinking about shortening them and changing out the springs, but I don't think I will bother and rather just install the stock shocks. Even if they are stiffer than the 6s shocks and maybe more tuned for bashing than racing, they seem to perform ok. However, I am a complete racing noob and have only been to the track a couple of times.

Alternatively, if I am not happy with the stock shock performance, I will go for the recommended Mojave/Kraton 6s shocks with the TA yellow springs. I think all the other aftermarket shocks are just a blind alley, not necessarily better than stock. Probably better to go directly for the top stuff if upgrading.
