Finally snapped a picture showing the current stance. It's not as pronounced as the stock one although with the Eibach adjustable front struts set halfway it's gotten some rake back after the multi leafs.

any have a β€œw” shape to their springs? mine seem to bow up in the middle by the ubolts.

Mine do, I wonder if that's why they have that spacer between the thin leafs and the overload leaf.

Mine were doing that too. Not sure what that's all about.

The main leafs are thin, thinner than the Tremor springs, thin leafs are a way to have a soft ride and travel, look at a set of Deavers for a F150, they have more thinner leafs than stock, and a overall thicker spring stack, I'm no spring expert as the title of this thread suggest.

This all started as just a alternative to the mono spring, which I never had, I found these searching for a spring to de-arch (you know, factory defect ride height :LOL:) and thought they might be a cheap multi leaf option for the standard Ranger spring, which a lot of people complain about.

Hopefully most are happy with them, they are not as cheap as they used to be.

Still happy with mine.
Same here. As for the 'W' I presume that was existent in the ROW models unless the position of the spring was different in relation to the axle?

I don't know of any anecdotal way to determine if the pinion angle has been affected but having had the truck at the um, upper limits of speed I'm willing to go it's very smooth and stable. No vibration that I can detect.

I seem to recall images that the pack was below the axle on some foreign models, which suggests a potential to level the truck without raising the front. Maybe I'm mistaken ? as that would suggest the U bolts would be all that's keeping the rear suspension together. I'll have to look for those images again.

Odd thing is the truck is rated for more weight carrying capacity overseas than USA.

i have no vibrations either, all good. just looked alittle strange. orientation is same as the AU ranger. tried finding photos of the leafs on there- hard to find. but as fitz noted- the downturned overload is probably indicative that these load up differently.

i’m thinking about dropping both overloads and going with a bds shackle to get the height back, and increase the flex even more. but- that also may exasperate the w shape ha

I removed the bottom overload and de-arched them 1.5" to level the truck.

The global application has the U bolts around the bottom of the axle and the plate on top of the spring, but either way the ride height is the same.

I had found a UK or a AU parts book reference to a high frame and a low frame, I never could find out what that meant.

I bought the Global springs thinking they would be lower in the back, it seemed to me the non-US truck pics did not have the back up so high.

something i discovered- if you look at the part numbers for dobinsons rear leafs- they are the same for us and uk/au.

I think all the global springs are the same, just the US gets the mono spring.

I think some rear shackles have length adjustment options but I'm not comfortable changing those dimensions as it alters some geometry in the rear. I think there are wedges available to adjust pinion angles?

I think I'd be reluctant to add blocks although I don't think it has a radical affect on the driveshaft angle. Maybe a combo of the two for lifting? That isn't one of my goals.
