Fox 38 service - How to Change your Travel or remove your air spring.

[@owensnicholas]

This is the first online guide I've seen so far that demonstrates removal of that stupid rebound adjustment dust cap. I just got a 36 and I had no idea how to remove that thing, and the manual doesn't say. Thank you!

[@spayrex_]

I mean its not stupid but yeah they are tightend really well and first i aslo didnt know how do get it off 😂

[@domanater480]

Thanks for the video mate, did my lowers and cleaned the shit ton of grease out of my air spring. WHAT A DIFFERENCE. its night and day. before i had literally no small bump now it feels so supple. I did notice my air spring shaft felt a little notchy when compressed fast which was weird, noticing it when compressing my forks to. Thanks again

[@Warby0]

Yep .... makes a massive difference.... glad I was able to help 👍 I haven't experienced the Notchy feeling when compressed fast ? not sure what is ....

[@Kirill_Sandalkin]

Great video tutorial! Everything is correct, consistent and with details. Thank you so much for such a job!

[@Warby0]

thanks for the feedback 👍

[@juancarlosguerreromarti7875]

Un muy buen video explicado con imágenes muy claras. Gracias.

Super pro, well done. Love the nurofen syringe

[@Warby0]

Perfect to measure the 3cc for Airside Chamber 😂

[@danielolave9146]

Great video. Nice work bro

[@Warby0]

Thanks for watching 🍻

[@dannnyw111]

please do a garage tour, like bike reviews and specs of the bikes your own and what you use them for? and also mtb tools you use/own :D

[@Warby0]

Ok, i will try and do a video in the future. 👍

[@pscjavvy]

Hello! New rider and great tutorial! Question-what is the the syringe adaptor used for the oil and where can I purchase?

[@hugor.b.6351]

flawless video very clear explanation... im going to change from 180 to 170 in a new 38, don't want to break anything and this helps a lot. Thanks !

[@Warby0]

Thanks for the feedback 👍

[@mrcarlincool]

And I'm going from 170mm to 180mm. Can I buy your 180mm air assembly?

[@hugor.b.6351]

@@mrcarlincool yep

[@tispokes1563]

It's easy to forget to shake the PTFE infused oil for the damper side. Please shake well 🙂

[@jhenry489]

Hi Mate, I’ve just grabbed some cheap new 38 Rythem’s for my Trance eMTB. The Trance is 140rear 150front do you think the 38’s @ 170 would be ok or I’d be better to drop them to 160. Cheers, great vid

[@chrisrae1254]

Great video mate! I got my LBS to install my new air spring and something went wrong when they were doing it. Couldn’t use full travel and air wasn’t sealing. They reckon the air spring was damage and the seals stuffed. Watching your video I can’t see how they can really stuff this up. Next time I will do it myself

[@Warby0]

Thanks for the feedback Chris ! How are your 38's now the air spring has been rebuilt ?

[@chrisrae1254]

@@Warby0 need to test ride it mate but he cleaned out a lot of grease in the air spring. Hopefully it rides good

[@chrisrae1254]

@@Warby0 now it’s sorted I’m going for a run later today. Still running the loan X2 rear shock. But I’ll mount my push 11-6 back on post service over weekend and test. The push coil is unreal with respect to traction and stability in gnar

[@mintsauce101]

I’ve seen videos where people use 20ml of fox 20wt oil instead of grease internal to the air damper. This stops the equalisation port becoming blocked and causing excess grease to pooling in the bottom of the damper causing poor small bump response. What’s your thoughts on this?

[@ThePalmiterfamily1]

Do you have to take apart the damper side as well why can't you just replace the airespring if you're increasing the travel or not to bother with the other side?

[@or-ian6973]

Thank you

[@eironordi1960]

Is that normal the Squeaky sounds after fork lower sservice? Thanks for answer..

[@Warby0]

No, no squeak is normal…… possibly rolled a seal.

[@eironordi1960]

Thanks a lot, but I already checked again its all normal inside.. is there any solution for that?

[@useport80]

can you please share your fork settings including riding weight, psi, and the clickers?

[@Warby0]

I'm 99 kg in riding gear- HSR - 3 LSR -6 2 tokens and 112 psi at 20 % sag 👍

[@czechxghouru]

Im confused, i dont think it was explained... how did u change the travel? I have 170 and I want to lower it to 160. Help pls. Is it all about changing the shaft? Or can I make mine 160 without changing the shaft. Thats all And thanks!

[@Warby0]

You need to purchase a 160mm air spring from fox. Follow this video to install the air spring.👍

[@walejandromoron3496]

Can I Increase the travel from 160mm to 170mm or 180mm? Or I just can reduce the travel on the forks?

[@Warby0]

You can increase or decrease the travel, but you will have to purchase a new air spring.

[@nishanpandey2261]

Hey mate do you know what's the thread size of air spring shaft? I'm trying to make my own tool. Cheers

[@Warby0]

Sorry mate, don’t know the the size… nothing is written on the fox tool.

[@sgoaty]

Do you have a part number for the knockers? Thanks

[@bernardkawiak]

Question, i've bought Fox 38 Factory 27.5 with FIT4 damper. The fork has 170mm of travel and i would like to swap the damper to grip2. It's a 820-18-336-KIT and it says 180mm travel. Is that going to fit for my 170mm fork?

[@vesko273]

Hi there. When i knocked out the air spring, the travel shaft fully compressed, as if one chamber fully decompressed and created a vacuum. Any tips on how to resolve this?

[@Warby0]

Did you equalise the air spring when letting all the air out ? Cycling the air spring should fix the issue. When you take apart / clean the air spring will also fix the issue.

[@traka795]

Hello. What is needed to change the travel on a fox 38? I want to go from 160mm to 180mm.

[@peterk7662]

Thanks for sharing this. Question for you, have you ridden the new 36? Would you say that the 38 is a bit smoother off the top?

[@Warby0]

Both are great forks, how much travel are you running ? 160 mm below 36 mm is fine. 170mm + 38 is better.

[@jamburgers]

hye. thanks a lot for this reaaaaaaaaaaaaaaally useful tutorial. what about the 15 cc in the right side that is on the chart ? where do you put this ?

[@Warby0]

Fox 38 Grip 2 - Air-Side of the fork = FOX 20wt. Gold - 20cc - All 38mm Grip and Grip2 Damper-Side Bath - FOX 5wt. Teflon Infused - 40cc - Not sure where you are getting the 15cc from ?? unless you have a FIT4 Damper.

[@307.William]

Thanks for the video!! When I removed my air spring I noticed that there was negative pressure just in the spring itself. Like, I can pull the inner small shaft and it will come out about 5mm or so, and when I let go it’ll go back 5mm or so back. Is this normal?

[@Warby0]

Recommend a airsping service, while you have the forks apart. I have a air spring service video on my channel 👍

[@307.William]

@@Warby0 oh I’ve watched it. Thing is I lengthened by 10mm with a new take off 170mm and it only has about 25 miles worth of use.

[@Myhandle59]

Good morning from England. Can you change it to 150mm aswell as I can't find any info on it anywhere. You can buy 150mm air shaft but a friend told me it wasn't a straight forward swap like 160mm and upwards. Any info would be 👍 👌

[@Warby0]

Yes you can buy 150 mm airshafts for 38's - Part number FX82002589 - yes it is exactly the same process to swap

[@lissildur]

did you change the travel? from 180mm to??

[@Warby0]

170mm

[@JoSantz07]

Can I switch my Fox 40 RC2 for a Fox 38 on same frame??

[@Warby0]

Won’t work sorry - fox 40 have 40mm diameter.

[@MartinTeerly]

So I need to buy two different oils plus shaft ?

[@Warby0]

Correct ✅ a flat faced socket will help with air spring removal

[@MartinTeerly]

@@Warby0 you don't need that just remove valve and you're ok

[@Warby0]

@@MartinTeerly yes that also works

[@l0wacska]

and where is the "Change your Travel" part? changing travel means 180mm to 160mm for eg. just to clarify the meanings.

[@Warby0]

Purchase a new spring from fox and follow this process

[@dannnyw111]

what size rachet did you use 3/8?

[@Warby0]

Yes I use a 3/8.

[@domanater480]

Hey do you need a new crush washer for this service?

[@Warby0]

yes, use new crush washers if you can

[@daxolivares6939]

Anyone got a link for those knocker thingy?

[@energ8t]

Wow... wish my air spring came out that simple. Mine was freaking welded in LOL. Terrible design. My 36 was WAY easier.

[@Warby0]

Ha ha yep, some are challenging….. the fox air spring tool helps a lot when they are stuck… & the transfer port is full with grease. hopefully your forks are feeling mint now !! 🎉

[@Tannervmtb]

Anyone ever had the air spring not pull out easy like that?

[@Warby0]

Yeah, some of them you have to give a all mighty Yank ! that is why the tool comes in handy.
