    Default Effect of length of leaf springs on wheel travel

    I have the following questions related to the subject.

    1. Will the wheel travel improve by increasing the length of leaf springs by modifying/ re fixing the shackle holders?
    2. Will it not effect the load bearing capability of the same vehicle?
    3. Is it recommended?
    4 Any other way to improve the wheel travel (not necessarily improving the comfort level).
    5. Will changing it to coil spring be a better option than increasing the length of leafs?

    Regards

    1. Yes definitely.
    2. Load bearing secondly and suspension frequency firstly will be changed.
    3. Obviously not
    4. Not with leafs. Not really i.e.
    5. Definitely not. Would refer you to Hardcore Jeeps with Leafs thread on Pirate4x4.

    Thanks for the reply. What i know and what i have discussed with ppl is that lets suppose, u go for a 4" longer leaf springs (may be of the same width as existing ones), what u do is that u move both the leaf holding mounts by two inches in opposite directions and fix them there. The tube remains in center in that case. So in that case also, is it not recommended?
    My problem is that in my LJ 50 when it was on original springs, it had better travel, even much better than jimny or SJ 410 ( because the width of the frame is less and springs are close to each other resulting in more travel), but it would not EASILY handle 5 ppl specially offroad/ hunting activities. So i added springs so that it lifts more weight but now the travel has reduced as harder springs lift the tire much earlier than what it used to be. So any recommendations?

    How many springs did you really add on there (front/back/both?) and how much did the travel reduce by? I would not think that adding leafs should reduce travel so significantly. Could be that the springs are stiff and will break loose after some bashing.

    In any case adding longer springs by moving both mounting points is a significant modification and unless you can find some info on the net as to how much to move and which springs to use, I would not recommend it at this stage. Working with existing springs and experimenting by adding/subtracting different leafs or maybe stiffer shocks should be a more predictable exercise.

    Very logical. Thanks for the advice. I added 1 spring on each side. The travel is effected surely and the reason is the extra ordinary light weight of the veh. The veh gets lifted easily with very lightest of stiffness in springs. Normal LWB suzuki's are around 1000KG and mins is around 600 KG's even after the extension project. Anyhow, will plan as u suggested. Thanks.

    Pictures would have helped a lot. But still, there are two easy to apply things that can help increase the wheel travel.

    1. Add U Type clamps replacing rivets & 'pressed' rebound clamps

    Effect of length of leaf springs on wheel travel -1163076
    Effect of length of leaf springs on wheel travel -1163077


    Riveted & pressed clamped system is good for high speed travel
    Effect of length of leaf springs on wheel travel -1163078
    2. Rearrange (by replacing, removing, cutting or adding) the leaf springs in such a way that the steps are longer. Meaning, there is more gap from where one leaf ends to the end of next in line.

    Effect of length of leaf springs on wheel travel -1163079
    Will additional body lift due to added leaves, appropriately longer shocks will also be required to avail that additional drop in diffs. during articulation.

    I would have thought that adding 1 spring to the leaf pack should not limit wheel travel. There is probably something wrong with the set-up or with the clamps (as Tareen has pointed out) and the leaf springs are not moving properly....
