Outer Limits 4x4 Board

Hi

I am replacing the shackles on the zooks and making some extended ones using thicker than std material, 50x6mm. or 8mm...

Thinking of stainless so it does not rust but is it strong enough?

Any other ideas would be appreciated.

cheers

stainless is prone to stress cracking from vibration etc. stick to mild. a decent primer, coat of 2k and a bit of ensis fluid (shell rust inhibitor) or similar and rust is no longer your enemy.

cheers

go with high tensile as per factory bolts. The load on shackle bolts is huge

Why dont you use cadnium or nickle plated high tensile bolts and use plated nilocks, no worries about rust then
