    6x6 or 6x4

    Hi all,

    Anybody running more the 2 axles?
    I have stated to see quite a few on the roads lately and was wondering what's the deal?
    Good way to remedy the GVM issues me thinks.

    The ones you see are probable EX mine vehicles.
    Not sure they are a true 6x6 but just extra load ability
    04 ST 3lt auto, not enough Mods to keep me happy, but getting there

    A lazy axle will allow higher payload, but render the vehicle useless off-road. You will definitely need a bogie drive where both rear axles are driven - then start thinking about all the locking arrangements.
    How about half-tracks - now there's a thought! Be great in the sand.

    @MB has a plan for this style of set-up in the future I believe - has posted a couple of times about it from memory?

    Retirement touring high GVM dream and research found to date has found Bob James to be the best in the business for our trucks, 6x6 over 6x4 for me all the way!



    http://6x6australia.com.au/

    Magnificent rear bogie coil system corners like a cat on carpet by slightly splaying axles under inertia minimising tyre wear on the highways yet keeping huge coil travel in the bush.

    Personally would never consider a 6x4 leafy as I’ve seen them get stuck reversing up a minimal suburban gutter lifting rear drive axle and rendering it useless.

    Yep as everyone has said... watched an empty 6x4 get bogged on wet grass and have to lock the hubs. They'd serve a purpose for some I guess.

    Just to satisfy my curiosity ........ is a ‘rear bogie coil system’ the the same thing as a load sharing tandem axle? (all wheels driven). I recently saw a FB video of this sort of setup on a truck & it’s hill climbing ability was very impressive. For those with FB maybe you can view it here https://www.facebook.com/PortoAlegre...wNjU1MzM5NDg2/

    Wow, that truck is quite the weapon Cuppa mate!
    I’m no doubt using the wrong terminology above but if you have a read through Bob’s website link above can explain his system better.
    Still load sharing as per pictures snippet below.


    Patented I believe power divider between the two rear diffs.

    As I understand the centre CHS pipe framework allows the axles to ever so slightly splay apart on tarmac cornering too which is a huge tyre scrubbing advantage for touring over rigid leafy 6x6 versions.

    6x6 or 6x4

    Just watched your video again @Cuppa mate and that trucks system appears to be some kind of single leafy/single axle-diff setup with dual I guess horizontal portal type axles to its dual rear wheels all pivoting off a single center point?
    Pretty cool monster truck for sure

    This system is a must for off road setups as a standard twin drive line a truck you'll be snapping uni joints in no time.
    If you can add a second pivot in the way of the rocker so both rears can move independent of chassis but together somewhat you'll be much better off.
    Make road worthy and engineering a little harder.
    But the ultimate setup..
