I flipped upper ball joints but had to much camber , really haven't had any ball joint issues tho uppers are at a bit more angle than stock so I can see it being a problem, but haven't had any yet. Fortunately I can change upper ball joints in a few minutes , and I check and grease all my front end often too so that may help out with not having issues. There is about 2.5" lift with the torsion bars also, actually had to trim my bump stops so upper arms didn't hit when it bottomed out tho.
I'm confused, or you are... The bump stops dont go anywhere near the upper A-Arms. The bump stops are mounted UNDER the frame, near the torsion bar socket, above the lower A-Arm.
Wait, you cranked the bars all the way up, hit the frame stops, flipped the ball joints, cranked higher, and still hit the frame, so you cut a recess in the frame?
I assume you mean you cut the frame extensions above the sway bar link?
You shouldn't have. If the UCA hits that, your ride height is WAY TOO HIGH. Lower it back down.
