and your shocks are mounted to the links...pretty out of the box

looks really weird though.
before you mentioned the winchrope i was havin a hard time graspin how it was stayin upright, ha ha

By putting the shocks in that location, I got 28 inches of straight axle travel from 14 inch travel shocks. It reduced the effectiveness of the shocks to 50%. But two shocks at 50% works out to 100% of a single shock, so...

In actuality I could have used stiffer shocks (Rancho 9012s and 99012s are intended for double shock setups anyway so they are always a bit soft). I will probably be switching to stiffer units as it gets ready to hit the trail again.

Mounting the shocks in that way puts a tremendous strain on the upper links. If you look closely you will that there is only on link (lower) on the rear driver's side. The upper snapped on the way to this trail after about 10 (edit: 100, not 10!) miles of washboard dirt road at road speeds. Fortunately as part of the heavy duty mindset, I used an old fashined parallel four link w/panhard bar approach. Loose any one of the four links at either end and you can continue on.

After this run, I beefed up the upper links a LOT and had no further problems. The current setup uses even heavier duty links all the way around. Since the rig will not see the highspeed dirt washboard dirt road usage that it did when it was still roadable, the links will not see that kind of stress anyway. The trail is a lot gentler since you are not trying to cycle the shots rapidly like you are in a washboard situation.
That is what puts the stress on the link. The shock just won't move that fast so it becomes a fulcrum in the middle of the link and the link winds up snapping in the middle from fatigue as the suspension tries to bend it right there.

Yeah, I looked at some of the other designs like you see on most of the rock crawling buggies. But for what I do with my rig, the simplicity, stoutness, and built in redundancy of the 4+1 setup works great.

(BTW, See my edit of my previous post... It was 100 miles of washboard, not 10 that broke the link...)

I'm doing the new links a little bit different. The shock mount will be removable from the link. With that and the adjustable length of the links (the lengths of the upper and lower and the front and rear are all close, but not exactly the same)... I will be able to carry a single spare, and not have to worry about the consquences of breakage until after I have broken three separate links! Not that I expect to ever break one again, now that I have determined the failure pont and the reasons behind it, and addressed them. But if something unexpected should happen, it won't be a big deal, no matter how far from the road we may be..

Ok, I'll play, still trying to get some rear flex.
This one is just before I flopped it :o
