These are the ones that come as standardIMG_2193.jpegAt first glance it seems that the thickness and width increase, I am unable to understand the angle.

Exactly what information are you hoping to obtain by looking at images of non standard leaf springs?

Unless you plan on manufacturing or modifying your own springs, there's not really a need to understand the fine details of the spring geometry.
That's why you go to a company that specializes in this area. You tell them what you want, or need to achieve and they use their experience to deliver springs that suit your requirements.

What do you need to see then ?
They look just like standard springs but a slight difference in centre bolt to rear eye measurement . If you look at the shackle end of you springs (the movable end). On standard vehicle the shackle pretty much is straight up and down. When you hit bump the force is applied to the chassis (straight up) because the shackle can't really move at first then flips back at the spring eye. If the shackle has a slight rear angle at the spring eye (The bump you just ran over) doesn't apply force to the chassis as hard because it can move back.

The upside to increasing set (the curvature of the spring) is increasing bump stop clearance .So said bump doesn't drive the spring into the bump stop (as well) and up your spine via your seat and posterior.

It all improves the ride (comfort) of our Cab Over trucks. Super singles I believe are a must as well. It also improves articulation when offroad, as you would have seen in some of my videos.

Ps. Dobinsons will ship springs to your country via their agents there.

Thick width, extended length and length between eyelets to calculate the degree of curvature

Standard width leaf, standard thickness leaf. They (spring makers) can best measure the length from your old springs. They probably already have a listing of what you old springs are measured at in their spring manuals.

They will work out what set (curvature) is needed to achieve what you want. If you want to lift the vehicle or not / how much you want the shackle to hang back. It only needs to have a slight rear angle. This increases with load.

Going back in my threads it seems that I had 30mm added to the length of the front springs. From the centre bolt position to the rear eye. And it looks like I only had 25mm added to the rear measurement.

If by chance your are looking at trying to find springs to buy (new or old) that will just be bolt in, well good luck with that.

Let's see guys, no hard feelings
When I ask for information I don't do it on a whim or because I'm a demanding customer.
Having said that, here in Spain there are probably between 10/15 Fuso Overlands units, there are very good 4x4 tuners who are dedicated to competition and could prepare the Fuso for the use that I'm going to give it, which is not exactly extreme 4x4, but first of all, the availability dates of these workshops are very high and the price, well, imagine.
The leaf spring workshops are mainly dedicated to the manufacture of leaf springs for non-offroad cargo vehicles, and they don't inspire me with enough confidence and I don't want to spend twice on the same thing.
If I were in Australia I wouldn't ask for information, making a shopping list would be more than enough,
that's why sometimes it can seem like I'm asking for information
having said all this
Thanks to everyone
Dan I have found a Dobison distributor in Spain, now I just need to have stock or order what is necessary for the Fuso, that's another battle, as I told you it's not a common vehicle
I use a translator
Regards.

In principle I will see if the national distributor of Dobinson has national stock, it seems that Dovidson for the Fuso uses the same system as fusoofroad 2 parabolic primary leaf springs and ballestin


This website does not have a photo but it is quite clear regarding measurements and in principle it seems that they correspond quite well with these that I do have in immediate stock.
