ball joint spacers for lift?

Would it be alright to do a 1" ball joint spacer to get just a little bit of lift? i'd do two inch blocks in the back to sort of even it all out (it'll look level with a trailer on it) any info is appreciated!!

Do a search for the topic if you haven't. I know it's been discussed before. Some have used them for lowering and I know someone asked about lifting. My question would be why? If you're only after an inch more why not just turn the torsions to get that inch?
