Before I get too deep, I am curious if anyone has experienced premature wear of wheel bearings after installation of spidertrax spacers. My search resulted in little information.
I was recently doing research on wheel spacers as well and I can tell you this question has come up a lot and I have yet to see anyone on the forum who has actually reported an issue with their wheel bearings. The most common complaints/issues all relate to clearance with fender liner/bumper but that's also a relatively easy fix if you're willing to do some trimming (dependent on tire size and lift).
