    Anybody seen this?

    It's from a german offroad factory. Even street legal!!

    For dd usage the DAS (double-add-a-leaf system) can be fixed at the rear frame (look close at the picture).
    Offroad it adds about 10 inches of flex.

    However it seems that the rear axle would be less guided with it.
    IMHO extended frame stress goes along with this setup.

    Does it work on a Fullsize?

    Opinions?

    This is called 3/4 Elliptic. Yes it can work on fullsizes. Denver75K5 runs a 3/4 Elliptic suspension on his K5/truggy thing. He is not overly impressed with it from what I have read though. It will flex good but it will do some weird unloading and allow lots of rear steer.

    I think you would be better served with a double shackle setup or Springer Style suspension. It can get you alot of flex but won't give you as much rear steer. If you drive a your truck onroad 3/4 elliptic might be very interesting to drive to say the least unless you could pin it in place to act like a normal spring setup.

    might be the angle the pic was taken... But i see those springs scraping everything you drive over.

    Thanks guys for all the information.

    @dleroy43:
    no more lift needed at that time. If ever, I'll go with a rear 4" shackle flip & 4" tuff country in the front. (Still have to do lots of reading about driveline angle, moving axle forward, zero rates, tcase drop etc.).

    However I'm still interested in your other stuff.
    Bad thing that I have lots of work on the truck until our Iceland at mid may.
    When will you leaving germany?


    Regards
    Walter
