    Marzocchi 55 rc3 tunning spring

    The default MZ 55 ti spring is too much soft for me (210 lb). If I put enough air pressure for me, 30 psi, that modifies the fork behavior to lineal instead of progressive and I don't like that.
    A possible solution is change the MZ 55 TI spring to a FOX 36 yellow spring but, Someone did it?
    The size of the FOX36 160 spring is 28x310 mm but I didn't find the size of the marzocchi spring (I try to avoid unmount the fork before change it)

    Thanks

    What year is your 55? I've got a 2013 RC3 Ti on my Chili, about 210-215 lbs geared up, and the spring is about bang on perfect for me. I'm running 2 turns of preload on it I think to get Craig's (Avalanche) recommended 25% sag.
    If jackasses could fly this place would be an airport.

    Hello & thnaks.
    My MZ RC3 is 2013 model. My setup was (I changed the oil to a 10w) all clockwise direction:
    preload 15
    compression 7
    rebound 15
    Air spring 30 psi

    I got a lot of fork's bottom out doing the same tracks with the same bike. Only changed my RS Lyrik coil RC2DH(black spring) to the MZ 55 RC3.

    I changed the oil to the 10w and the behavior of the fork is totally different less plush. For that reason I'm looking for a different solution, may if I change the spring to another more firm may be helps me to avoid bottom outs and maintain the same behavior

    Regards

    I just got a used 2010 55 rc3 ti. I'm at the other end of the spectrum: 145lbs. There's a bit of stiction so I can't get an exact sag #, but averaging it out looks like it's going to be less than 20%. The seller told me it's the stock spring, but I can't guarantee that. I pulled it out to get the measurements in case I can find another spring to work. It's red, does say titanium, and 7.3N/mm. Measures 30x287mm. Hoping to find a lighter one. What rate is listed on other's Marz springs?

    Speaking of Avalanche, I just had them rework my Fox CTD shock. I bought the 55 partly because I knew I could get their cartridge for it. I might end up doing that if I can get a proper spring for it.

    Marz only makes one ti spring for the 55 I think.

    my riding weight is 180 & the 7.3 Marz ti spring was too much for me. Marzocchi USA headquarters in Cal. told me that spring weight is for people in the 200 lb.+ range. i believe it. so, i ordered a 6.5 i believe, but when they said $280!, i cancelled the order. got ahold of Marz Vancouver B.C. & got one for less than 1/2. ask for Naz. he knows everthing Marzocchi.

    Nice, good to know they make different springs. I'd heard here in another thread a year or so ago that they didn't.

    What sag do you get with the 6.5?

    i double checked my spring & it's a 6.0. i get 1 1/2" sag, no preload & no air. Marz Canada has access to other springs i think

    Yep, I think you will have to be imaginative when it comes to changing springs on the 55. I think Marz designed pretty much just one spring (with maybe the lighter option) because of the two preloads available.

    I have a 2013 on a Nomad, and it seems fine to me. I weigh about 230lbs. Plush on the small/medium stuff, great bashing through the rough, but I have only taken about 3-foot drops. Does not seem too soft for me yet. With all the adjustments, I think I can adjust most problems out for individual trails.

    Are you folks using the 55 like you would a 66? I put a 66 RC3 on the Nomad for DH last summer, which took much more of a beating. And I even beat on it more than I do a 55 on my local trails. 66 is an amazing fork, though very heavy.

    Hi, Enrico from Italy here. Thank you for the dimension of the spring, i was struggling to get that. It seem very short to me, fox is 310 and rs 320 for 160 forks. However, since i would like to shorten to 150mm, i know i have to find a 277 coil... tnx.

    Following the thread with great interest, if someone is able to use other spring inside the fork, please let us know...
