Arrma 4x4 BLX 3S shock rebuild tutorial

Affiliate links:

Here's a video I put together that explains how to disassemble the whole shock and rebuild it like new. A lot of blood, sweat, and tears went into this video (especially blood)! Hope you enjoy it.

This is prolly the best of the Arrma rc DIY repair channels on YouTube. Thorough and detailed but with brevity. Great video

Honestly thank you very much for your content....you wouldn't believe the hours and stress youv'e saved me.

This video has been a huge help for me as all 8 shocks on my big rock crew cab and typhon 3s blx have dumped all their oil. I ordered the kits to rebuild all 8 shocks, also bought silicone grease and a pick set for o-rings. Last night I did the 4 shocks on the big rock and took it out for a test run this morning. I have to say it went really easily having watched your guide many times beforehand and having it on the TV while doing the first shock. Unfortunately my local hobby shop ran out of rebuild kits (what a surprise) so I'm waiting on them to be able to service the typhon but I'm feeling so much happier about doing this job now although there was much less bloodshed when I did mine - hope that doesn't mean I've done it wrong ;}

Thanks for video after I watched ran down to Harbor Freight tools and bought the Viton 180 pc o-ring assortment and rebuilt my shocks this evening went flawlessly!

That is really a brilliantly designed shock. I never knew they were like that. Thanks!

I just got a fairly new Senton, and one of the shocks was leaking. This helped out a ton, thank you.

Awesome! Thanks for making this, as one of my Granite 4x4 shocks is leaking and I need to do this service.

Thanks for this. I just picked up a big rock for my son. I wanted to check and top up the shocks but couldn't figure out how to disassemble them!

[speedracerxtreme]

Glad they improved this shock design with the Vorteks 3S!

New to hobby. Super easy video. Have 2 3s arrmas that we got this year and I haven’t serviced anything yet. That’s my plan this winter. Thanks for doing these videos even tho it’s yrs old lol

Brilliant video helped me get the shock apart to straighten out a bent shaft. Thank you

[MrGrimmyGrimshaw]

Great video thank you kindly. You saved me a bunch of time figuring out how to open the shock 👌

[josephdonkers]

I bent the piston toot much to unscrew the end cap or to straighten the piston without damaging anything. I used a bent pair of needle nose pliers to get the end cap off. Worked really well.

Helped out a lot for my first time rebuilding a shock. Thank you.

[rikirolld]

Thanks, my shock strut was bent and I managed to straighten it after watching your video.

Pretty comprehensive how-to. I believe the problem with the O-rings leaking has more to do with the material they are made from than anything else. Arrma seems to have realized this too as now they offer a silicone kit to replace the inadequate rubber O-rings. Part # ARA330022. Even if they hadn't I'd still recommend silicone over rubber.
Alternatively the plastic wrench included with the truck has the adapter to remove the shock caps as well.

I actually picked up some aluminum shocks and plan on running them off road. However I also plan to repurpose the original shocks by adding an internal spacer to shorten their stroke. This should work well for short course and on pavement running.

awesome video very clear ive actually just used this video to strip and rebuild my own shocks so thankyou :) also for anyone struggling to get the inner o ring out and the spacer inside the shock (i didnt have a pick) using a really small flat head screw deriver and pushing on an angle from the other side did the trick for me

Great video Razor! I'm looking to pick up the new Typhon 3s buggy in the next few weeks. This video will come in handy.

[davidcornwell]

That video was a great help in me 1st time rebuilding by shocks. Thank you so much!
