    Hi,

    New member here but 30+ years kombi owner, currently own Trakka converted syncro which over the years has sagged on the drivers side (due I think) because of cabinets and underslung water tank. My question is, how can I fix this problem, I love this bus and its capabilities and over the time I have owned it done heaps of improvements, now time to do the saggy bit. All advice appreciated.

    Thanks guys.

    P.S. I have fitted packers above spring with limited improvements, I need a proper solution not a quick fix.

    Thanks guys, this was great news, I contacted a suspension "specialist" in my town and was told there were no such kits.

    I fitted the Gowesty syncro progressive lift springs not long ago and was disappointed because they didn't do what was claimed other than lift the bus.
    Thanks

    I've been reading on the Vanagon Owners Group on Facebook that a lot of people are having problems with the GoWesty springs sagging after quite a short time. GoWesty also sell shims but you said you have something in there already?

    Hi there,
    The springs seem ok but I was under the impression that they would renew (or help) the way the bus sits, in fact all they did was lift the bus which does help offroad. Yes I also fitted Gowesty recommended packers which only part made a difference.

    I guess the only true way to correct the sag is to replace ALL suspension components.

    Would that do it? The springs control the ride height and I thought all the other bits were to keep the wheels pointing in the direction of travel.

    Replacing all the bushes and links wouldn't change the ride height would it?

    How much is the sag? Could you put +50mm springs on the driver's side and +25 on the passenger side?

    Don't know about the GW springs, but thought this should at least overcome the issue for a while.
    Probably only option could be suspension kit from GMB... but it's a price option.

    maybe you could just lower the other springs? :D

    OK - seriously........ is it lowered at the front or rear?
    Or equally on the passenger side?

    Rears are pretty easy to change?
    Was thinking if you just whacked a set of good springs in the rear just to see what happens?

    Are syncro springs the same as caravelle springs?

    Just a little left field here but the yanks sell pump up shocks. Not the most conventional way to lift suspension but it does work as long as the shock mounts are strong. I'm not talking gas shocks, these shocks you fill with air just like pumping up tyres. Alternatively full airbags can be fitted. If you go that way get fat bags they ride much better, then take pics and let us all see

    Thanks all, I followed up on SYNCRO27's suggestion and contacted www.airbagman.com.au and through discussion with Ben in detail about this problem, I think this will be my best option.
    Cheers Kev

    I had a pair airbags custom made for my Delica they bolt in and can be removed and coils refitted with no real effort. Cost just on $1000 including the tank and compressor and switches operate from the dash. But they are skinny bags and give a harsh ride. Ok wow just had a look at the link. They have moved on a lot since my install. Very nice wireless remote lift. Not sure why though but nice just the same.

    Just out of interest how much is the difference between left and right, front and back - if you know what I mean. It does seem a little bit odd that the new GoWesty springs just lifted and didn't level it out.

    Drivers side is 30mm lower than passenger side, looking at the bus front and rear sag is only passenger side, measurements taken on level ground on all four corners at outside edge of bumpers.
