Question about metal, corrosion, seized bolts, etc...

What can I use for the sway bar disco upper bolt and bushing sleeve so they dont seize together? I had some kind of steel bolt and an aluminum sleeve (from Rusty's, the name should have given it away hahaha) and I ended up having to cut through the sleeve and bolt with my angle grinder since they had become 1 solid piece over the last 3 years. I dont wanna do that again. Whats a good metal combo, with or without lube, that'll stay fairly easy to remove in the future? And is lube a good idea, or worth worrying about for that spot? Should I get a greaseable bolt?
Thanks!

ijeeep

Steel and aluminum aren't a good mix without special treatments and coatings. Galvanic corrosion is a thing. There's books and charts on the subject.

​​​​​​Bronzes and maybe Delrin and Nylon 6-6 would be the first things I'd be looking into depending on application.
