    What are the benefits of coil springs over leafs(off road wise). /forums/images/graemlins/usaflag.gif /forums/images/graemlins/burb.gif /forums/images/graemlins/usaflag.gif

    Coil: Pros
    - All forces can be controled and performance increased by individual links (Brakeing force/Exceleration forces = one link, Lateral forces = another link, and so-on) Less of a comprimize needs to be made.
    - Positively locates the axle assembly under the truck with the required links.
    - Power is transferd directly to the frame via solid locating links. (less prone to "wheel-hop")
    - Ability to infanatly adjust anti-squat/anti-dive carataristics.
    - Ability to position the roll-center/s as needed.
    - Suspension can react quicker to changes, when compared to leafs, and therefore gives a smoother/cleaner ride. (eliminate friction between the leafs, usualy weighs less also)
    - Ability (for us) to use extreamly long locating links, and if done correctly, more controlled wheel travel.

    Coils: Cons.
    - Complex system
    - Load carrying cabability is typlicaly less when compared to leaf-spring suspensions
    - The over-all packageing can be dificult to fit

    Leafs: Pros.
    - Simplicity, the most basic suspension design.
    - Load carring cabability, nothing can carry a load (or over-loaded) like a leaf-spring.
    - Easyily change spring rates, ride-heights, load-carrying, ect. By simpliy adding/changeing individual leafs or the compete spring pack.
    - Positively locates the axle assembly, for and aft, as-well as lateraly

    Leafs: Cons.
    - Slow to react to changes. Friction between each leaf as-well as the overall weight can slow the axeles ability to change to road conditions
    - Bulky design can be difficult to locate
    - Forces on the axle assembly can deform the spring
    - Wheel-hop

    Thats awesome twiz, great info

    do you or anyone know what causes wheel hop? I cant figure out why that happens, sorry for the high jack, twized answered your question damn well.

    Thanks twiz.

    Wheel hop is caused by the twisting torque off the wheels, it trys to twist the whole axle assemble up when torque is applied to the wheels. Trac bars will prevent the axle twist therefore directing all the torque to the wheels.

    He said it, the pinion is rotated up and then when there is enough energy stored in the spring, it snaps back down and then winds up and does it again.
