Outer Limits 4x4 Board

I'm sure that this has been covered before, but I need some guidance specific to a job I am working on ATM.

Will this work on the trail?




Its all very rough at the moment and all arms and tabs are mock ups only, but you get the idea. There is no lateral movement at ride height as it sits now, but I am concerned the molly uppers either won't work as their straight counterparts may, or the lateral forces may cause them to bend further??

Opinions please.

PS. They are bent to clear the motor, as it has been moved back 200mm and down 150mm.

May well be the stupidest thing you have ever heard, but if you filled the links with concrete (yes, I said CONCRETE!!) it should stop the tube from bending. Very common technique in the building industry for large beams.

Rationale is that the steel is good under tension, and the concrete is good under compression - now have a look at how the forces would act on the tube to bend it further than you have. The greater arc of the tube would be under tension and the lesser arc would not have the capacity to collapse towards the greater arc due to the space occupied by the concrete. The concrete under compression of the two sides of the tube would not allow the steel walls to move.

Known as composite steel construction I believe...

Is your heart set on a 4-link?

Why not turn it into an A-frame?

It looks like you have a panhard bracket on the DS of the diff there. Why not just run 3-link plus panhard? Its hard to tell from the picture but your lowers look fairly straight and there doesnt seem to be a heap of triangulation in your uppers either. Surely a 3-link+p/hard would be the easiest option round the engine and still have good lateral location. Please correct me if Im wrong though.

Whilst I have no first hand experience myself, Ive read that 4-links in the front are'nt much chop for anything except dedicated offroaders anyway. Apparently they can be vague in the steering. Again, just going off what Ive read, not built.

I wonder if the panhard's going to swing that diff off enough to bind the heims if it moves over that much.

Whats wrong wtih an A frame? or 3 link?

Links like that have been done many times, only thing is I would go to bushings not hiems at the chassis end to prevent the links from rolling.

Thanks for the coments fellas.

Think I will lose the hiems at the chassis and laminate the arms inside and out. to stop it from bending.
