Hi guys., not modding but more of replacement now, have anyone purchase a complete set from ebay before and it should be ok right?

found set like these for under $300 for my 2007 is350.. been rubbing the tires when I turn and go over bumps. Any suggestion., thx all

 

I don't have any experience with that directly, but kits like that have been around forever, because it's a normal wear-and-tear replacement item. My thinking with such things is that the lower the price, the shorter the life span. I would expect longevity to be directly proportional to cost. Of course, actual experience will vary. So I'd think that this is fine, just don't expect it to last as long as OEM. Don't be surprised if you're replacing it again in 5 years. In the end, the overall total cost ends up being the same. So I generally go with OEM, since I don't like doing the same project over and over, and I hope that in the end, it's worth the cost for fewer replacements. But maybe some cheap stuff will happen to last a really long time too. It's possible. So just go into it with the right expectation, and you should be fine.
