  • Dobinson c59-327

    Hi Guys,

    Quick question.
    I am looking at getting the c59-327 for the rear.

    It measures around 410mm free length.
    Is this classified as a 2" coil, or as a 3" coil?

    My plan is to stay to a 2" coil, to avoid any serious issues,

    Will I have problems with brake lines?

    Thank you

    I took the 327 off my 150 GX because despite 20000km it was far too high in the rear. Yes it gave a good ride and yes it carried heavy outback trip loads well but when the car is empty [ most of the time] it sat too high at about 840-850 mm. I am sure that the problem is that the 5 seat GX is about 100 kg lighter than the GXL and most of that is in the rear. The ride when empty is also fine but I wanted no insurance hassles with a car which was well over the legal 50mm lift. The 327 may well be fine with a GXL or above or if you regularly have 100 kg or so in the car. I now have 325 with polyair air bags in them. It is currently sitting at 830 mm in the rear with little air in the airbags. This gives a good ride, more clearance in car parks and no potential legal hassles with the option to put up to 30psi in there if the load is heavy. I had the same set up in my previous 120VX and it was fine over about 80000km. [In that case the springs were ARB mediums so very similar.]
    Dobinsons say a 50mm lift. No issues with brake lines etc. The 327 and 325 appear to be the same length when I put them side by side on the garage floor but the 327 is just harder to compress. Check the spring rates in the data base? From memory [bad] standard is about 170 ft/pd, 325 is 220 ft/pd, and the 327 is 270 ft/pd. Horses for courses but my guess is unless you run loaded all the time the 327 may be a bit much for a 120.

      Thank you for this.
      Yes that was my concern, I always want to go bigger I think I wil OPT for OME 889 which is 400mm, and then 260 spring rate i can get some nice dicount at a store here,

      I think for my loads, the spring (327) will be too stiff and too long.

      Thank you

        The 327 surprisingly is not a stiff riding spring but with its higher rate it just sat too high for my liking

          Anyone else to share their experiences and thoughts?

            The 327 is a good length / rate for lightly loaded vehicles. Go much softer and it will pitch off-road and sag too much when you put any load in it.

            Many run longer 270-280 coils.

              Re length, that's about your shocks open length. Springs won't effect your brake lines. You don't want to springs to fall out at full droop.

                Drwormy that is true but when the car is 100 kg lighter to start with in the rear like a GX the 327 has it sitting just too high. Put 100kg in it and it is fine with height.
