These pins makes the arms near the bulk heads have no more wiggle/ nice and snug/ works great- and doesn't weaken the upper arms in the front from the rpm ones that you counter sink to have steering clearance
Nice calling out the instructions add. Would be very helpful for some things. I ended up grinding down the rpm heads similar to how gpm made. Great vid.
Yeah it's really annoying to get a bag full of parts and no information on how to use them. Usually you can figure it out but like in this case I really don't know why those rubber o-rings were in there. Someone said they should go under the head of the bolt and I guess maybe that's the space it off the arm to make it easier to install but I tried it and then the nylon part of the lock nut doesn't engage. It also doesn't clamp down on the arm as well. I'm fine with just leaving them out.
Hey buddy with these hinge pins I got a question are the two that go on the outside of the Hub the same length and the inner upper a-arm pin I know the really long ones go on the bottom inside and the shortest ones go to the shocks so other than the really long ones and the really short ones are all the other ones the same length or are they supposed to be I went cheap on an AliExpress kit not sure if they sent me the right length LOL thank you very much for your time I appreciate it
Thanks for sharing. Would these work on the 6s XMaxx as well. I am waiting on a 6s to arrive, and want to know good upgrades for sure. Would love to see more 3D printing for sure.
I just took a look at it and if you're talking about how to get the nut in there I'm pretty sure there was a bit of finger gymnastics involved and using one of my very small pairs of pliers or maybe even a very small wrench. I don't exactly remember at the moment sorry.
@@DoRC didn’t show how to fit the rear upper only front as there is no space for nut for rear would be interesting if can make a video how to do it. You’re doing great job and your videos are very helpful. Appreciate it
Hey man did u use a flexible filament or did you use a hard filament just wondering yours look like they came out really nice! I would definitely scoop a pair lol
Even by my xrt…does it even bevore also happen alot the pin flipp out even sometimes you didnt even crash him a lot?? Oh and for what you using the o- rings, where?
Yeah it's pretty common for the pins to come out. I ended up not using the o-rings. From what I've heard they are designed to go behind thin bolt head to allow it to be easier to tighten. I didn't find them necessary so I just left them out. Thanks for watching and if you aren't already subscribed a sub is appreciated :-)
The orings seems to be over-torque strain relief. They go under the head of the hinge pins, but not at the top outer front pins...more on that later. The oring squishes as you tighten the connection. Too much torque will squeeze the oring off. This way you can screw on the nut just til the pins' thread passes the nylon of the nut without any axial pin slop. As for the top outer front, no washer at all for maximum clearance for the steering knuckle. Actually, no washer at for the front upper arms. The thin metal washers are for the shocks.
Yeah I ended up not using any washers or o-rings on mine and it was just fine. Simply tightening until you just reach the end of the threads allowed them to be pretty much perfect with no binding whatsoever. Been running like that for a while now and I haven't had any issues. I'm sure running the o-rings will be fine but I just don't see any need for them. Thanks for watching and commenting and if you enjoy the videos a sub is appreciated :-)
I wash my vehicles with a hose after pretty much every bash and then blow them dry with compressed air. It keeps them pretty clean. I'd also fairly recently done a near complete rebuild on this truck so that helped too
I don't usually provide links or information on where to get things for two reasons. First I don't want people to think that I'm making money off affiliate links cuz I don't make money off of any of this stuff and second whatever link I do post will likely not be valid a month from now because they change all the time. You should be able to find them through a Google search though. They're available through several different sources. Thanks for watching and commenting :-)
Not entirely sure. I ended up omitting both of them and have had no issues with it. I think the o-rings might be a space the bolt heads away from the arms so they're easier to get to but they also stop the lock nuts from completely seating so I just left them all off and it's been fine.
Yeah I tried to use them on both sides and wasn't really happy with either end. I don't honestly really see any reason to have them at all so I just left them off. It's possible they are there just to make installation easier since the heads of the bolts are so thin but I have A pretty wide variety of tools that allows me to install them easily anyway. Plus I like the idea of The pin bolt itself clamping down on the sides of the arm reinforcing it and having that o-ring in there would reduce the strength of that.
@@DoRCm2c hinge pins come with the o-rings aswell but i don't see why unless its to stop binding but you can use a washer instead. I left them out aswell
The only thing I can think is that they are there to make installation easier by spacing the little thin head out from the arm. Personally I tried it and it actually prevented the nylock part of the nut from engaging completely so I just left it off. On all of mine when the nut bottomed out on the threads it was basically perfect as far as tension was concerned so I didn't even use washers.
@@DoRC i noticed that with the nyloc nut aswell the thread could do with being a few more mm more still works fine though none of the nuts have come off.
I don't doubt that the quality is better but the new stuff coming out of GPM is also very good. Their old stuff was kind of crap but They made some big changes about a year ago now and their new stuff is way better
I'll have to check it out though keep in mind that titanium typically isn't quite as strong as good quality carbon steel so unless you need the lightweight it's not necessarily advantageous
@stitchcompany291 I'm not sure. I don't really know the specific metallurgy of the GPM stuff. I will say that these particular parts seem very strong and are probably at least on par with titanium.
@@Dakmaxx1218 I'm honestly not sure. People of speculated various different reasons for them to be there but I've run several sets of these now and I've never used either the washers or the o-rings and never had a problem.
Yeah not only are they making much better quality stuff but they're bringing out stuff that no one else is doing. It's crazy that it took this long for this kind of upgrade to become available. The RPM option was okay but this is far superior. Thanks for watching!

Please do a overview video of your xmaxx. Would love to know what upgrades and mods you have in the truck sofar.
I might do a video overview of all my cars at some point and could go over it then. Not sure it would really make for its own separate video.
Wow! Thank you! I lost a hinge pin after an RPM Arm install on my 8SXMAXX and I don't want to countersink my arms at all!
Yeah unfortunately the RPM arms are really soft and tend to spit out the pins. This kit definitely should help!
@@DoRC Finally received my GPM hinge pins, they are bulletproof and easy to install thank you! New sub!
@@randyboisa6367 nice! Yeah mine are still holding up great as well! Glad you're enjoying and thanks for the sub:). Almost to 10,000!
Pretty awesome pin setup! Would love to see more on 3d printing for sure!
Yeah it definitely has its place in RC! I think it would be good to expose more people to it so a video will be coming :-)

Couldn't find it on the Internet or TH-cam so I thought I would pick your brain
I don't remember for sure but I think they were all slightly different lengths.
Sure please do some 3D printing RC parts. Keep it up Kenny!
Yeah I think a video about it would be helpful for some people. It definitely has its place in RC!
You didn't show it in the video but does this kit include the front upper inner as well?
There are two different kits. The one that has more pins in it includes every hinge pin in the suspension as well as the lower shock mounts
Thanks for sharing. Would these work on the 6s XMaxx as well. I am waiting on a 6s to arrive, and want to know good upgrades for sure. Would love to see more 3D printing for sure.
Yes. The hinge pins and mounts have been the same throughout the entire life of the X-Max as well as the XRT.
Nice one got the same just curious how did u fit the rear upper one?
I just took a look at it and if you're talking about how to get the nut in there I'm pretty sure there was a bit of finger gymnastics involved and using one of my very small pairs of pliers or maybe even a very small wrench. I don't exactly remember at the moment sorry.

I used tpu.
Even by my xrt…does it even bevore also happen alot the pin flipp out even sometimes you didnt even crash him a lot??

@@DoRC An off topic question: I assume that truck was well used before you did this video. How in the world did you get it to brand new clean?!
I wash my vehicles with a hose after pretty much every bash and then blow them dry with compressed air. It keeps them pretty clean. I'd also fairly recently done a near complete rebuild on this truck so that helped too
What printer would I suggest getting for Rc parts?
Any of the bambu lab printers are a great option.
No link. Hope you tell in the video where to get them

First I don't want people to think that I'm making money off affiliate links cuz I don't make money off of any of this stuff and second whatever link I do post will likely not be valid a month from now because they change all the time.
You should be able to find them through a Google search though. They're available through several different sources. Thanks for watching and commenting :-)
@@DoRC understand, thanks. I ordered them!! New sub
Awesome thanks!
Great video and product but what is the part number.
Not sure what the part number is. If you just Google GPM x-maxx pins you should be able to find it
So washers and o rings are????
Not entirely sure. I ended up omitting both of them and have had no issues with it. I think the o-rings might be a space the bolt heads away from the arms so they're easier to get to but they also stop the lock nuts from completely seating so I just left them all off and it's been fine.
the rubber o ring goes next to the head of the new pin bolt
Yeah I tried to use them on both sides and wasn't really happy with either end. I don't honestly really see any reason to have them at all so I just left them off.
It's possible they are there just to make installation easier since the heads of the bolts are so thin but I have A pretty wide variety of tools that allows me to install them easily anyway.

That's cool. Yeah the way I have mine set up is working great too!
Nice upgrade
For sure. It makes disassembly slightly more annoying but I think it's well worth it
M2c makes some very similar hinge pins for this platform. I'm not sure if they do the shock pins though, nice to see those included with the GPM pins.
Yeah I just looked those up. Very similar though twice as much for fewer bits :-). I'm sure they're good quality though.
@@DoRC The M2C option might cost more...but, their quality is WAY better than GPM. 🤙🏼
I don't doubt that the quality is better but the new stuff coming out of GPM is also very good. Their old stuff was kind of crap but They made some big changes about a year ago now and their new stuff is way better
Unlimited Engineering makes some pretty cool shit. Titanium.
I'll have to check it out though keep in mind that titanium typically isn't quite as strong as good quality carbon steel so unless you need the lightweight it's not necessarily advantageous
@@DoRC is the steel used by GPM stronger than titanium used by UE?
@stitchcompany291 I'm not sure. I don't really know the specific metallurgy of the GPM stuff. I will say that these particular parts seem very strong and are probably at least on par with titanium.
ah GPM o rings. those are there so that you will watch a you tube video... other then that they seem to serve no purpose for suspension pins.
Yeah I don't use the o-rings or the washers and have not had an issue.
What are the o-rings and washers supposed to be for?@@DoRC
@@Dakmaxx1218 I'm honestly not sure. People of speculated various different reasons for them to be there but I've run several sets of these now and I've never used either the washers or the o-rings and never had a problem.
gpm sure have stepped up their game in the past couple of years
