springs

Does any colleague know where I can get the measurements? I'm trying to find the options here in Europe

Here in Spain I have these spare parts, but of course to adjust them I would need measurements.

You have your own truck, don't you?
Use a tape measure.

These improvement kits vary the standard measurements, so the question is?

As far as I know, most of the parabolic springs that are produced in Australia for the Fuso and Isuzu light trucks are designed to be a straight replacement for the OEM springs.
I believe that the parabolic springs have a slightly longer eye to eye distance, as this changes the angles of the spring hangers. If the hangers are not vertical, the spring response when you hit a bump will be different, as the forces are directed differently. Basically, the spring response will be softer if the spring hangers angle slightly outwards.
There are a multitude of other differences between OEM and parabolic springs, but you can research those yourself.

If you are only after the actual technical dimensions of the parabolic springs, simply contact one of the suppliers and ask for them.

I should add...
From memory, the front springs on a Fuso are about 100mm shorter than the Isuzu, which give then a harder ride.
To get a softer ride out of these trucks, one modification is to reposition the hangers on the chassis, which allows for longer springs to be fitted.

Simple solution. Leave spring hangers where they are. Take a front and rear spring to a spring manufacturer. Get them to measure them and add 25mm to the length from the centre bolt to the rear eye. Increase set on the new springs by about 60mm in height. This will bring eye to eye length near enough (slightly longer) to old length. Shackles will hang slightly rear on spring (compared to chassis) end instead of straight up and down. As SkiFreak mentioned .

I changed from 5 leaf front to 6 leaf front. Rear leaf numbers stayed the same. Leave the rear helpers in place, it will sit on them only when you are in full articulation. You will need 2.5 degree wedge for passenger side front and 3 degree wedge for drivers side front. (spring to axle wedge)

You will end up with about 50mm suspension lift. The front axle won't bottom out all the time and improved ride.

You will need shock absorbers that are longer in full extension to cater to the raised height and increased travel of your suspension.
