    I came back from a year in Afghanistan to find my $1300 Fox coil-overs looking like they were salvaged off the Titanic. Has anyone here encountered this, or know a means to combat it.

    I took them off once to clean with just about every type of rust remover on the market, and they reappeared like this. I've also e-mailed Fox with the enclosed pics to see if their service can clean them up a bit.

    If anyone has any advice, I appreciate it, thanks.

    Wow man, that is terrible! Wonder if they have a coating they could add to it. Icon's got a coating for $100 more!

    wow that's crazy. I think this happens to all coilovers after awhile. I used silicone spray on my SAWS and it did seem to help a bit.

    in a thread I read some guy said Fox's are made of steel and can rust where others like King use aluminum.

    Not true, they all make the body from steel

    I disagree, I have owned many fox shocks over the years and never had rust. Without maintenance any shock will rust.

    Yeah but put any shock through that without maintaining and it will rust over time.

    I reccomend you go back and do some more research.

    Kings most definitely have aluminum bodies. Aluminum dissipates heat faster then steel so your top of the line manufacturers like King utilize it.

    Not true at all. My Kings are 100% fine after 2 years of salt belt abuse.

    [​IMG]


    From Kings site:

    Lightweight hard anodized 6063 aluminum alloy reservoirs dissipate heat quickly and will not rust due to gas charging contamination.
    Aluminum components and vehicle specific mounts are machined from aircraft quality billet. Front and rear kits all include all necessary vehicle specific mounting brackets and hardware along with detailed installation instructions. Technical support, if needed, is only a phone call or email away.

    No i recommend you do more research, both king and fox use DOM steel for the shock body. The reservoirs are made from aluminium.

    "The shock body is made from low carbon DOM steel tubing then honed and threaded."

    Just wondering how many shocks have you opened up and rebuilt?

    So why is it that after 2 years I have corrosion on the bodies and threads not rust?

    I don't see what rebuilding a shock has to do with metallurgy.

    its the coating they use breaking down. If you don't believe me call king and ask them what their coilover bodies are made from.

    Ive done more than just bolted them on, thats what.

    King must electroplate their shocks then.

    I have never seen corrosion similar to aluminum corrosion on steel before.

    Guess you learn something new every day.

    :facepalm: I think you need to do some more research on who the "high end manufacturers" are.

    If you live in the salt belt the IVD coating from Icon does a terrific job at keeping your shocks clean and new looking.

    You work with ALOT of shocks and installs. In your opinion does one brand have a better coating than another? (not counting the old sway aways ha) IMO they are all very similar
