Default Stainless Spring Bolts

I have a rusted solid bolt in the sleeve of one of my rear spring bushings, happens to be in the leading fixed end. These are normally I think SAE grade 8 or JIS 12.9 bolts.

Has anyone ever thought about using stainless? I know they use them on boat trailers that get dunked all the time but not sure stainless would be sufficiently strong on a vehicle.

One justification I can see is people often use greaseable bolts where are line bored and cross drilled. This takes away some material in the bolt, might be that removing 20% of the cross section of a grade 8 bolt is closer to a full cross section 316, which is similar to grade 5 in equivalency.

"Our task must be to free ourselves from this prison by widening our circle of compassion to embrace all living creatures and the whole of nature in its beauty. Nobody is able to achieve this completely, but the striving for such achievement is in itself a part of the liberation and a foundation for inner security. " --Albert Einstein
