QA-1 lower control arms with factory upper control arms

[Richie]

Hi everybody.

This would be fine to do right? All the geometry would be correct you wouldn't need the QA-1 uppers?

QA1 control arms are designed to install piece by piece, so it should work. But the general consensus from what I've read is the lower arms don't make much of a difference from good-condition factory stock. Unless you got a screaming deal, I don't see a reason to just do the lowers, but I will defer to someone with more experience.

You'd be better off doing the uppers, and just boxing the factory lowers...

The QA1 LCA’s have all the stock geometry points, so they can be used with other stock components.

But yeah, I would be much more inclined to run QA1 uppers with boxed stock lowers. The uppers give you more caster and improve geometry. The lowers don’t really do much of anything with the new bumpstop design they have, except shed about 8 lbs off the LCA’s. Now if you do some work on that bumpstop you can get some extra suspension travel. But that’s only a benefit if you’re significantly lowered.
