Longer Leaf Springs

Post by Ruggers »

What effect will putting longer leafs have on my middy i can get some 75 series cheap and the fronts the are the same but rears are longer by 100mm so what effect would longer springs have on it. It will also move my diff reward i have a couple of sets of extended anti inversion shackles so will the fit and be softer with leafs reomved. thanks for any help chris

longer springs

Wont work. The extra length will require the end to be "squeezed/bowed" up to meet the shackle

It can work, but 100mm is too long. The longer leaves have to be reset to the straight eye to eye length is the same as original, to retain correct shackle angle. That means the only way is up for the eyes. 100mm extra length will be a huge amount of lift.
The problem is, most resets dont last, and eventually they sag. This eventually means the shackle starts to lay flat. Eventually, it cant lay any flatter, and the shackle pins start to pound, and cut, the bushes. If your lucky, the pins dont fail.
I found this all out myself, halfway to Cape Melville on Cape York. An extremely awkward and slow painful trip back to Cooktown was had.

It can work, one of the most common mods to a suzuki is rear springs up front.
BUT

This involves doing a chassis extension, wich moves the shackle mount forward, by doing this it also moves the diff foward so you have to unpick your shock mounts, break line mounts and bump stops and weld them back on forward with the diff.

A longer spring in the front will give you a softer ride, more fire wall clerance and greatly improve your wheel travel, but it is alot of work to do it properly.

Can you move your shackel mounts rearwards? If you can, do that and put some big anti inversion shackels on, it will work fine :cool:

you'd shorten your wheelbase though wouldn't you. Generally a bad thing :)

Ok are u doing this to your front or rear diff? Front leaves on the middy should be fine just remove a longish leaf, the should flex well.
