I have an 06 duramax with a 4.5 bds lift, I never did add the 1.5” wheel spacers at the rear to match the width of the front axle,but wanted to add them. I heard a few negatives about them as far as them losening off and being hard on axle bearings. Maybe it’s not even an issue.apparently there are some different spacers,some more expensive than others, anyone have any info on this?
