No issues. I've read all of the hearsay horror stories though. I ran the cheapest of the cheap spacers on my jeep, off roaded often, no issues. This kind of built up my confidence for them.

I pull fishing boats, ATVs, dirt bikes with this truck. Lots of hwy miles over the last year, no issues.

Here's a link to the set I bought: https://www.amazon.com/gp/aw/d/B07XKRCNT9?psc=1&ref=ppx_pop_mob_b_asin_title

I'm cheap, but these have worked just fine. (Knocks on wood)
