Shackles

Post by cruiser_beast »

Hey every1,

I was working at an engineering shop and on my last day we werent doing much so i rushed around the steel racks looking for some 50 x 8 mild steel flat bar to make some new shackles for my cruiser. I couldnt find any 50X8, found 40 x 10 and heaps of other stuff, but then i found, some 50 X 7 flat stainless steel, i cut it up into lengths and was interested to know if it would still be suitable to use stainless steel.
Its harder than mild steel, so i guess less fles would be apparent.

Yea, any suggestions, otherwise i guess ill just have to go buy some mild steel flat bar.

I wouldn't use stainless, as it is prone to work-harden and crack over time. Mild steel is probably the best stuff to use. I've attached (or I will try to - if it doesn't work then check my personal pics folder and I'll drop them there) some pics of the ones I made.


40 x 10 might be ok to use, as thats what the beefy hilux ones are made from - the only problem will be the factory pins will be a bit short going through 10mm.

So i guess i should try and get hold of some mild steel flat bar then. Is 8 mm thick the thickest you should go with the cruiser standard pins?? So i deally you reckon 50 X 8 mm thick mild steel for landcruiser shackles???or 40 X8?????i notice that the standard shackles are only like 5mm thick.

Cheers.

50x8 is fine. The problem with bigger is that for every 1mm thicker material you use, you take 1mm from the inside measurement of the shackles, compressing the rubbers / urethanes up more and limiting twist of your springs.

Ideally you would make new pins as well, but this gets expensive as they should be high-tensile. 18mm bolts are about $15-20 each from memory... so machining them is almost cheaper...
