Hope this is not true. Moog Offset Upper control arm bushings.

i can't count the number of posts/threads that insist you need offset upper bushings. I have never used them or saw the need. My vehicles all steer and self centre fine with stock replacements.
Are you sure you needed them?

"Need"? Sure, you can get by without them, and have adequate results. But if you're replacing your upper bushings anyway, why not just get and install the offset bushings and take advantage of the opportunity to optimize your setup? It doesn't cost much, if any, more than stock replacements.
You don't "need" headers or to replace your two barrel with a four barrel, either- but we do.
