Aftermarket ball joints?
 

Are there any companies or hell if they even exist that do offer ball joints that would last longer than the oem ball joints for a leveling kit, since they will most likely be worn out quicker than usual.

Get ones that are greasable, and keep them full. It'll last longer, how much longer depends on the size of that level, how good the alignment is, and how hard you beat on the truck..

A set of greaseable Moogs should do the job.

x2. I got 120k miles out of OEM ball joints ( previous owner did more highway than anything however ) but I don't expect it ever put ball joints in my truck again with the better Moogs.
