Do I need upper control arms?

[bowtie-till-i-die]

I've asked this question before, didn't really get any answers, so I'll try again.
I have a 98 c1500, swb, reg cab, 2wheel Dr with a 4/6 drop on 20s. I'm going through upper ball joint boots as fast as I install them. The angle of the control arm is putting the ball joints at such an angle that the boots rip.
My question is should I invest in new upper A arms for lowered trucks? Or, I've heard of some guys taking 88-98 c2500 upper A arms and flipping them over and then switching passenger side and driverside. Has any1 heard of this? I've seen some at the pic n pull and it looks like it would work

Not into the lowered trucks, but I would go with the control arms made for lowered trucks. On a 4x4 if you flipped stock arms like that you would have the shocks rubbing on the arms.

How is your front drop done? I've put a lifetime of miles on 4/6 (and 5/7) dropped GMT400's with springs & spindles and never, ever tore up a ball joint like you're describing.

There are some special ball joints the bagged guys sometimes run but I forget what they're called. You really shouldn't need anything but stock, though.

Those guys will run K1500 upper joints because they allow greater angles.

Really...that's a funky combo. Doesn't it put your scrub line really, really close to the ground? In other words, bottom of the lower arm very close to the ground?

Usually a 4" front drop is springs + spindles, no issues whatsoever.

There a lil low, but that's how they are designed. 15 years ago control arms were the way to go. If I could swap em for springs I would

this is what I'm talking about. My stock A arm is putting my ball joints in an awkward angle, aftermarket A arms change that angle. So I think I found my answer.
I've also heard of people taking the stock A arms and flipping them, then switching the drivers and passenger sides, because they are offset.
