Like the title asks, is it really a necessity to have adjustable upper control arms for a solid swap? I just wonder how many people out there with adjustable upper control arms with the same pinion angle as fixed or stock length control arms?

Do alot of you really have your pinion angle adjusted far from stock, or is it to compansate for different wheel/tire combinations that drag race oriented owners tend to change often?

I wouldlike to have a decent launch, I'd be happy with a 1.8 second 60' on my 28" M&H drag radials, would a fixed upper control arm work for me??

Different bushing types require different pinion angles due to how much they deflect, gets some adjustable uppers they arent much more than non adjustables. I have mine set between 1 to 1.5 degrees pinion angle.

Alot of good info found here.

Thank you very much, mustangjohn.

if u do much drag racing then i would say yes buy the Adjustable UCA.. because for street driving like posted above you need a 1.5 pitch maybe more angle! But more angle usually adds more forward drive and better 60ft times.

Not "mandatory" but strongly suggested!

if your looking for a great set of upper control arms i would use baseline or team z re-located uppers.
