I see them on EVERY Aussie rig I've ever looked at. Truly a W.T.F.

I cant figure out why this would be intentionally, seems as though its in the most prominent off road country's or areas. Do they know something I dont?......Like how and where to achieve useless flex?

The Man-a-Fre catalog is full of pics of them.


.another case in point

There are a lot of manufacturers that make stock length springs that are stiff by nature because they are very short (Toyota front and rear) and are supposed to provide lift. Those springs will almost always have a vertical shackle angle. I've had Superlift springs, Pro-comps springs, and 53 inch (or so) Deaver springs on the rear of the same 80 pickup. The pro-comp springs were too short and almost provided a negative shackle angle/vertical shackle with the stock shackle. I returned them because they ddin't flex worth a damn and were too short. The superlift springs were the appropriate length for a little bit more positive shackle angle but were stiff and still didn't flex (Toy factory hangers are just too close together for any real flex) so I took a 1 leaf out of each spring. They flexed GREAT 1 trip but fatigued to the point of riding on the bumpstops after 1 hour on a pretty rough trail. The deavers I had were already broken in and my friend welded them in according the deavers instructions and I ended up with a great shackle angle. Most AllPro/Marlin/Sky/Trail gear setups you see will have a relaxed shackle angle once broken in. 90% of the time a crappy shackle angle just comes from an aftermarket stock length lift spring.
