Greetings:

I have an esoteric question regarding some frame bolt “features”, that will most likely be of little interest to the general community, but here goes….

The five (of six) 1/2 x 1-1/4 bolts (used in nearly all frame bolt locations), that hold the frame to the front clip, each have a SPACER under them that does not “appear” to serve any purpose other than to keep the nut from seating more than ~3/4 threads showing.

The bolts at the “cross members”, which would appear to be as “thick” as the frame to front clip would be, have ~ 4/5 threads showing and that does not appear to be a “problem”.

I have all the correct bolt sizes and spacers for replacement, but was just curios why GMC would have thought the spacers (additional expense) were necessary in the first place, rather than just the washers and more threads showing – The spacers also appear to be about the same diameter as the washers used, so it doesn’t seem to be for load distribution.

Like I said, just a curious esoteric questions to see if anyone had some insight as to why GMC felt they were needed – Thanks for any thoughts you can share!
