Hello all, first time poster here. I know there are quite a few GMT-800 HD / H2 guys here so I hope someone can help me out.
I recently bought some Upper Control arms from a well known company (not naming names until I figure out what's going on) that do not fit on my truck. Part numbers, fitment, etc has all been verified as me having the correct part numbers.
The issue is that the control arm legs are not spread far apart enough to fit in the mounting brackets. My stock control arms measure 12.5" (12-1/2) apart from the inside of the bushings, while these new arms measure about 12.25" (12-1/4).
I am being told that "Those older HD's are pretty inconsistent" in their frame construction. I have a hard time believing that GM would allow for this much variation. I am also having a hard time imagining that spreading the UCA pockets out 1/4" will not cause undue stress on the frame and arms over time.
The truck has never been wrecked and aligns perfectly so I do not suspect any frame damage causing this. The stock arms are easy (with a few mallet taps) to install and remove. The truck in question is a 2004 Yukon XL 2500 8.1l.
Any suggestions? Any help is appreciated!
