Might be a daft question but I want to replace the rear shock mounting bolt that holds the rear shock onto the swingarm on old Santa Cruz Heckler I've just got and am doing a rebuild on

Question is, do these bolts have to be high tensile steel or can stainless steel bolts be used for this ?

Have tried contacting Santa Cruz but got no reply and Fox distributors said they only sell the mounting kits not the bolts and I should contact Santa Cruz to ask them, so I'm kind of stuck really

The rear allen bolt looks a bit rusty and allen head is usable but not great condition so I want to change this bolt
The front ones look ok but I might replace those too and same question goes for those really

Basically just need to know if these can be stainless steel bolts

    I think that it is shear strength would be more important than tensile strength. Even so with the best SS - A2 you will get 85% of alloy steel tensile strength. There will be a galvanic effect too but looks as if there is one anyway. I did hear that SS bearings had an issue with tensile steel cases because of some obscure pressure related effect causing it to cold weld.

    I know a lot of people substutute substitute bolts and I've not heard of any disasters on this forum. SC have provided bolts that rust so their comments might not be that valid.
