Hello,
well i personally would not mind leaf springs, as they are tough&simple (even put less stress on the frame
). But the biggest bonus of the Iveco is always the engine.
However i am always gratefull for any informations about frames, because to this day they is very little information out there. People compare engines and axles of various offroaders, cars and trucks alike, all the time, but the very backbone is always never compared.
And what you say is also very interesting, because i looked into this myself a while back and got mixed answers.
As far as i know the Defender frame is 185x70x2mm in the mid section, making it the second largest of its class. (after the Toyo J200 with 185x90x3.2). But the very thin metal compromises the strenght and is of course a problem with rust.
So i too was thinking, that the Wolf Defender might have a stronger frame, but this answer from richards chassis made me doubt that:
To our knowledge all Landrover Chassis were constructed using 2mm rails sides and top and bottom strips, I have seen a few wolf chassis and they
were 2mm. The series chassis used 2mm. 130chassis are also 2mm. I have never seen an original Landrover chassis of any other thickness.
All our replacement chassis use 2.5mm steel on the rails, 25% thicker than
Landrover.
This was always strange to me because i know there are Defender Version with a GWV of 4-4.5 tons and in that weight class frames are usually a LOT stronger.
Greetings
