    How to change '08 Fox DHX 3.0 coil spring

    Hi everyone,
    I want to replace my DHX 3.0 coil spring into the harder one by myself.
    I want to know what is the right tools for the job and the step-by-step guide to replace the coil spring.
    I did check the Fox website and it only shows the manual for forks.
    I also search mtbr and didn't find anything about replacing coil shock, so really sorry if this thread is repost.
    FYI my bike is stock '08 Giant Reign X-1 and I live in Indonesia so don't expect nearest PUSH or even Authorized Fox Dealer to help.

    no tools required.....loosen the preload ring, lift spring up, remove the spring retainer, then slide the spring off

    it's all in the manual: go to rear shocks, dhx, dhx 3.0, then click on changing springs

    He may run into an issue w/ the lower reducers. There is another thread on this subject in the Giant sub-forum here: http://forums.mtbr.com/showthread.php?t=475255

    Pipes10: Don't get me wrong, you gave good advice.

    Gembong: Please post up when you do the spring swap and let us know if you were able to get the reducers out by hand or if you needed a vise or bolt extactor. Some have been able and some have not. I haven;t tried on mine but I'm kinda curious now.

    I actually changed the spring on my DHX 3 today. Its on a 2008 Reign X1 aswell. I couldn't get the reducer out by hands so I went to a bike shop and they simply used a vise to get it out. Very simple in fact and I'll do it myself if I ever need to do it again.

    By the way, I weight 145 pounds geared and I quite happy to have switched from a 450X2.37 to a 400X 2.45 spring. The bike gained in plushness and track better than before.

    OK, it's done. Pipes10, you were right about it, but I have to use the special tool for loosening the preload ring, it called hook wrench, otherwise you could damage the preload ring.
    VerT & nightnerd, both of you were right too about the vise. Luckily I found one on my father's garage, and yes I do use the vise, it's a lot easier. Just make sure to put something proper to prevent damage from the vise. FunniIly I use folded newspaper, and it works.
    Now my Reign X-1 should be ride better, nearest hill here I come! Thanks a lot, fellas!

    if the preload ring is too tight to turn by hand u can firmly grasp the spring and turn it....that will loosen the preload ring enough so u can turn it by hand...no need for a special tool

    Just did this on a DHX 5. Used a center punch, a vise, and some finesse to get the reducer out/in. Kind of a pain in the ass but worked like a charm in the end. Now I just need to get out and ride with this new Ti coil...

    Just swapped the lower reducer on my '07 DHX 4 air. Found this thread when I got stuck. No vice on hand, but used a socket and a 16 oz finish hammer- worked.
    I wasn't biking while I was typing this... I call that wasted time!!!
