    position of shocks on rear axel

    While sitting in traffic jams I have been staring at rear axels and noticed that many utes have the driver's side shock on the front side of the axel and and the passenger side shock on the rear side of the axel. However, some makers of 4x4s and SUVs have both shocks on the same side of the axil.

    Is there a load/articulation/handling advantage to having the shock absorbers on different sides of the axel?

    Offset shockies are fitted to leaf springs to reduce axle tramp. Coil sprung axles usually have much better axle location.

    Early RR classics also have offset shocks.

    I think its still in relation to torque reactions though. Rebound damping is stronger so i think its about maximising that to reduce the torque reactions.

    Hmmm very interesting. I am in the swings of making a camper and was going to put shockies on with leaf springs. You have given me something to think about and learn!
    I had never even heard of axle tramp before. Although i dont have much to do with leaf springs apart from trailers. Thankyou for that.

    I could be wrong but my understanding of axle tramp is that it only affects "driven" axles, It shouldnt be a problem on a trailer axle.

    I am thinking of putting a set of shokkies on my boat trailer to help reduce any damage on the nasty corrogated roads that i frequent on my fishing trips.
    I would be interested to see how you set up yours on your camper trailer when you get it done.

    All my trailer builds have had shockers fitted. My choice was for VW Beetle front shockers as these are very short, ideal for trailer suspension.
