8s rigs 10mm shock alternative?

[aametzger]

Yea, my plan was to try to match the stock rebound. So for preload, besides ride height and making the springs a little stiffer, what other behavior does it generate? Right now I think I am at about 20-25% preload for my tests. @L3phturn I wanted to take a min to thank you for your interaction with this thread, and the knowledge and advice you are sharing. It's much appreciated!

thanks man i will give it a read for sure.

Update. Filled the shocks with 6000wt and I think we are really close. Definitely close enough to do a drive test. Probably going to rest run it tomorrow.

How's your clearance to the drive shaft? I got some big bore losi 5t shocks and i had to run some thinner springs to clear. i think it sits lower than those though by the looks of the rod ends.

You know to be honest i didn't even think to look at that. I will go out and look here in a min. Thanks for bringing it up! I was so focused on the other things I overlooked that part. Side note I am running the stock arrma springs not the ones that came with the rovan shocks.

I wondered if the OD on the bodies was bigger with the beefier shafts. May be a good thing the stock springs fit. They def wouldn't fit the big bores.

Looks good on clearance. See below, first pic is the stock front, 2nd pic are the rovan rears. Springs are really tight at the top collar and the bottom perch, I have to convince them to go on and off with a flat head screwdriver, but then they have a nice snug fit, so less likely the spring will come out of the perch hopefully.

Right on. If i hadn't already gone this route i'd snag those. If i ever go titanium drive shafts i'd probably want those for sure so they would clear the thicker shafts. I need them, i break rear drive shafts way too regularly hahahaha.

what shock oil do you run in those shocks and how many holes in the pistons?

I don't remember now, I think 50? but the springs are super heavy duty. I don't remember piston hole count either anymore.

 

[Capt.Fignutz]

those are beefy shafts! love it

 

[aametzger]

Did a run tonight and i'm undecided on if the current oil weight is the sweet spot. There were a few jumps that it seemed to kick the rear up more than normal, but it could have been what i was jumping. I think I just need more time with them to know for sure, but at a base level they work. I did break a rear hinge pin, but that's not the first time this has happened, so....

Subscribed for when this gets dialed in. This is a great idea for an upgrade!

Thanks I will keep this updated for sure. I also may move them over to my kraton 8s once I get it rebuilt with the m2c chassis. I will also likely move them to the front at some point to collect more data. Unfortunately the weather is crap here in Ohio so it will limit my testing. When I took it out friday thinking it was going to be cold enough that it wouldn't be too muddy. Yea.. not the case..

Also in case anyone is wondering which arrma springs im using, pic attached. They are the harder of the 3 springs arrma offers. The outcast comes with the medium one out of the box.

^^rig is looking awesome so far! Yeah, I’d be doing this mod on my K8S if you get good results. I believe my chassis is slightly bent from some of the bashing I’ve done so far, but nothing crazy. I tried to increase the preload on my rig to reduce the amount of chassis slap, but it’s just something I’ve grown to live with.

Yea I bent the crap out of my K8s chassis when I lost power in the air (motor wire came loose) about 20ft+ up. It lawn darted nose first.

I got it on video if you want to check it out. Its towards the end of this video.

following this thread, thanks for experimenting. Those shock shafts look beefy compared to the stock ones.

Beefy isn't the right word for them. One shaft has more material in it than all 4 of the stock shafts put together. I bought a set along with some paddle tires.

 

[u189961]

hahaha! I need to see these in person, might pick up a set and experiment.
