    Default Leaf springs, coil springs and Shocks

    We all know that these three elements, ie leaf springs, coil springs and shocks perform somewhat same job in a vehicle's balance, comfort, wheel travel etc etc. As far as 4X4's are concerned, different people over here have different opinions. Like few say for loader vehicles, more leaf springs are required. Few say, we need to have extra shocks. The width of leaf springs, height of coil springs and the angle of shocks also play important role in a 4X4's over all behaviour.
    Having said this i request everyone to share his experience against the above observations irrespective of what brand they are keeping.
    Regards

    THE BEST SETUP:
    Leaf Spring + Coil-over Shocks.

    In this setup you get all the 3 ELEMENTS! ENJOY!

    Suspension frequency is a good place to start when thinking about springs & shocks and comparing different suspension setups and responses while the Pirate4x4 Coilover bible is a great way to remind yourself that one should never think that you fully understand 4x4 suspension tech: Pirate4x4.Com - The largest off roading and 4x4 website in the world.

    What's the purpose of having two shocks. I could not understand this logic. I think it might be good for hardcore off roading but would be of no use in rallies. Suhaib bhai might be able to educate us as he has the experience of desert relly.

    Double shocks are only used for high speed applications to basically stiffen up the ride and in certain cases to prevent shock fade (shock oil heats up and loses damping). There isn't much sense of double shocks for offroading where you need a softer suspension to roll and climb over obstacles, too stiff would not be helpful especially for slow speeds.*Besides in most cases one can find one stiffer shock valved to the specs of two single ones...

    Generally on leaf sprung vehicles double shocks should be avoided unless being used for a specific purpose or specially valved to match the spring rates. Normally the car becomes too stiff to be of any normal/enjoyable use. Coil sprung and IFS vehicles put more stress on shocks and double shocks are more relevant but only for high speeds apps....

    On loading vehicles, double shocks could be used and prove useful to some degree, but a bigger stiffer leaf pack is a cheaper and longer lasting alternative which perhaps also works better in many ways.*
