    Fox Volume Spacers WTF

    I have an Ď18 fox performance dpx2 shock with a couple hours ride time on it. After setting sag , Iím bottoming it out on 4-5 foot jumps. I talked to Fox, who gave me the volume spacer part# 803-01-251 (float x kit). Hereís the kicker: Fox says they donít have that kit, and donít know when it will be in stock. The rep told me to look online. Everyone is backordered on it. This crap is going to drive me up a wall. Any suggestions before I ditch my Fox shock for something else? If anyone is wondering, Iím 200lbs.

    Add air? Sag is a very, very, very crude and incomplete/improper way to adjust your suspension.

    If you need the volume change, fine, but don't rely solely on sag to say that your pressures are "right".

    Thatís a great point, and I did that until the fork was all around harsh. I really hoped it was going to be good enough out of the box. I spent a long time on the phone with Avalanche yesterday, and Iím going to have him tune it. Once Fox comes out with the Ď18 can replacements, Iím doing that also.

    I modified a few volume spacers to fit the DPX2 damper shaft using a step drill.

    Did you use the older style float spacers? Avalanche is starting me with a .6, but heís out of everything else except .95. I would definitely mod an old style one since it seems easy.

    What size do you need? I have a DPS Performance and have 0.6 and 0.4 volume spacers I am not using.

    A main cycling has 0.4 an 0.2 DPS volume spacers (https://www.amaincycling.com/search?s=fox+volume+dps)

    good luck. I started a thread about this last month. 180lbs and was having the same issue with bottoming out. Every LBS and online store I went to that showed stock was out until November. Check out ebay. They seem to have a set or 2 pop up every other week, by bike shops cleaning out inventory. I ended up finding a compromise with increased psi that seems to be working for the time being.

    You can use a thick grease to take up some of the space inside the air can. I pack under the stock bottom out washer at the top of the shock. Even if it gets out it will not hurt the shock. I ran this setup for years.

    ^What he said; volume is volume. Grease or oil by their nature is more adjustable anyway.

    Thatís actually a great idea. I donít think the time involved in programming would be worth it. The entire kit is only $35. I have a guy getting them for me when he tunes the shock.

    spacer

    Stock Float spacers on left, modified Float spacer on the right along with the stock DPX2 pink/purple spacer. I used a 1/2" step drill and an Exacto knife. The plastic is soft and easy to work.
    My DPX2 worked great at Snowshoe on a Bronson with this set up.

    lol. Fox releases their 2018 products, but they don't work without extra parts, and you can't get the extra parts until it's actually 2018. Brilliant marketing strategy.

    I'm trying to buy a 32mm topcap socket for a 2018 Fox 36 so I can service my fork. Unavailable. See how the marketing strategy works as a cohesive whole?

    Yeah it's dumb. I installed a MRP ramp cartridge in my '18 fox 36 fork on Wednesday, and just used a regular 32mm socket. It worked fine and didn't mar or round anything. Is that the right way to do it? Nope.

    I like the modifying of the older float spacers, I will do that if I need to adjust them more when the shock gets back from avalanche.

    Good trick, does it matter what kind of grease? I have white lithium, EPX, and slickoleum. Slickoleum might not stay in place, while the white grease or EPX isn't very slippery and could add stiction if it gets onto the shaft.

    I used lithium heavy bearing grease. Slickoleum would be way too thin. The thicker the better it will stay in place.

    Thanks Alex!
    I've tried Slickoleum but it doesn't stay put. I'll try your grease suggestion.

    Thats what I was thinking. Plus I have a tub that is still 50% full after close to 20 years. I need to start finding more ways to use that stuff!

    250lbs tried green spacer first, not enough difference so put the orange in.

    Pretty colors! The kit I got a couple of years ago was all black. I see the green fork spacers in the background. The older Fox 34 10cc spacers I have are yellow and the new ones I just got are green. The yellow are 234-04-950 and the green ...953. They appear identical otherwise.
    Do the math.

    How much do you weigh, what front and rear suspension do you have, and what spacers do you use?

    I felt an immediate positive improvement when going from 1 to 3 on my front 2018 fox 34 rhythm fork. I've been hawking the online sites for a few weeks looking for the rear kit.

    What's particularly amusing about this is that injection-molded plastic accessories have the highest markup. Those spacers literally cost pennies to make. Pure profit!

    They changed to prevent rattling in the stanchion.

    Sorry to bring this up, but a question on the spacer sizing. The stock spacer in my shock was a black one (no labeling)...is the next size up based on the diameter or the depth of the spacer? The yellow one in the kit has the same diameter as the black one, but it's way shallower...is it correct to assume the volume effect is based on diameter and not the depth (they are all pretty much narrower than the stock black one)?

    Their effect is 100% the volume.
    You could make a spacer that is wider and shorter and a different one that is narrower and taller and if they have the same volume their effect would be identical.

    So if your yellow spacer is the same diameter but it's shorter than the stock piece then it will have a smaller volume reduction effect on your shock.

    They do make a big difference. I ended up with 4 spacers in my fox 34 and JT allowed me to reduce the psi a bit for a more supple ride and still prevent bottoming (tuned with shock wiz). I was starting to do same for the shock but sold the bike...is bigger guys really need these spacers imo

    Speaking about volume spacers I have the following dilemma.

    My current shock setup (Fox Float X Evol) is a bit different vs. what is considered to be normal. More specifically I run 40-42% sag, quite fast rebound and I have the second smaller spacer installed.

    The ride quality is quite good, I use 95% of the travel and I rarely bottom out. On top of this the BB is low and the head angle is slacker.

    On the other side the bike doesn't pedal that great, feels a bit wallowy and I get some pedal strikes but not too many.

    Despite the fact that I am quite happy overall I have this feeling that I am missing the middle solution between the above. Would it make sense to remove the volume spacer and add a bit more air? I guess it will decrease sag, increase the ride height but I am a bit worried about making the small bump sensitivity and bottom out resistance a bit worse.

    Did you have a 2018 DPX 2 modded by Craig? If so how you liking it?

    What bike?
    And What spacer did he add after the mod?
    Curious

    I had a couple long talks with Avalanche, and decided to try spacers first. I have the largest spacer in, and am still not happy with it. I havenít rode since a few weeks after my last post, so it hasnít pissed me off enough to send it in. Once life slows down, I will most likely send it in. (I even bought a replacement shock for when the original is getting modded)

    My bike is an ibis mojo hd4.

    Collecting data on spacers used for DPX2

    Great thread here. I've started collecting data on what other riders are using for spacers to see if there's a common theme that works.
    Here: Float DPX2 volume spacers - survey

    Thanks!

    If I work to pay for my rides - then why am I at work right now??
