Upper Control Arms - Offset Cross Shaft

[LuvNLife]

I've been doing some reading about the use of offset cross shafts on upper control arms. Many of the people using them do so because their frames are "drooping" or sagging inward, and it makes alignments a nightmare. I don't see this as an issue for me, but it did get me thinking.

On my '87 short/wide, my upper control arms have quite a stack of spacers on both sides, way over 1/2" thick. My question is, since I'm going to redo the bushings or replace the upper arms anyway, would I be better off putting in the offset shafts to eliminate or reduce the spacer stack?

I cant see how the frame would sag inward, the alignment bolts aren't even directly connected to the frame, they are mounted to a beefy L shaped bracket riveted to the crossmember which is then bolted to the frame. Also the motor mount brace would keep the frame from sagging. I dont think using spacers are a problem as long as you have enough bolt to align the truck.

As long as the offset is less than your shim pack thickness they should work.

I have them. Helped me with getting the negative camber out when I dropped it 6 inches.
