Outer Limits 4x4 Board

Me and a friend have just bought a suzuki sierra fo 100 bucks that we are going to build into a comp truck, we are going to do a triangulated 4 link front and rear with coilovers but we dont know what metal to use on the suspention links, if any one could tell us that would be great.

Unobtanium X-infinity is by far the best material to use, but it is a bit hard to find on this side of the galaxy.





Failing that, 250MPa structural pipe from somewhere like OneSteel will do the job, just make sure it is large enough. Strength comes from diameter, not wall thickness. You just need the wall thickness to be enough so it doesn't dint when dragged over rocksa.

thanks mate i'll look into that.

Mate sign in to OFN, and start learning. Its the Bomb.

All Superior Engineering Lower and Upper Arms are made from 20MNV6 or otherwise known as Mecavel.

20MnV6 is a carbon-manganese steel micro alloyed with vanadium, generally supplied in the black hot rolled condition with a typical tensile strength range of 600 - 790 Mpa and a high typical yield strength range of 440 - 570 Mpa.
Characterized by excellent machinability due to silicon - calcium treatment and precise control of the sulphur content, excellent weldability with high yield and tensile strengths due to the micro - alloying effect of the vanadium.

The low carbon content and the vanadium addition allows surface hardening by carburising, carbonitriding or nitriding. It will also respond to high or medium frequency induction hardening and can be through hardened and tempered producing a moderate improvement in tensile and yield strength, this varying depending upon wall thickness.

20MnV6 hollow bar is used extensively by all industry sectors for a wide range of applications utilizing it's considerable saving on machining time and weight over solid bar.
Typical applications are: Bushes, Cylinders Various, Conveyor Rolls, Hollow Shafts, Hollow Parts and components, Nuts, Rings, etc.

Much less in strength in my opinion you are wasting your time.
