    Default Tapered leaf springs

    Bought a new, very cheap set of 1000KG trailer springs and discovered after, that they are a single tapered leaf. I've never seen them before, so my question is, how do they compare to the regular multi leaf? Better, worse or what?

    Thanks

    i think their called parabolic springs work ok especially on boat trailer application where rusting occurs between leafs on a normal spring pack

    tlbsg has it spot-on. They're parabolic springs, and from memory they're made in Adelaide. Melbourne Trailer & Caravan Supplies down here carry them on the shelf. They're available in both black and galv'd.

    If anything they're a little more forgiving when slightly overloaded as they don't have a hole drilled through the middle of them for a bolt.

    Good spring, never had any dramas. Only ever seen one snap in half... surprise, surprise, over-loaded.
    Too many projects, so little time, even less money!
