Whats Better, Adjustable Uppers or Lower control arms?

I have aftermarket lower control arms already that are not adjustable. I have 2 inch lift. This came with the rubi when I bought it. I want 4" lift. So I was looking into adjustable uppers and keeping the lowers. Should I get lowers or uppers that are adjustable?

Adjustable length uppers will be a better choice. Your 4" lift should be set up with a SYE kit and CV driveshaft and you'll need to adjust the rear axle's pinion angle to make it all work right. Adjusting the rear axle's pinion angle with adjustable upper arms restores wheelbase lost to the taller suspension lift. Using adjustable lowers to adjust the pinion angle would further shorten the wheelbase which would not be a good thing to do.

When you have a choice, buy American.

Thanks Man That was my thought too. I don't need either or for the SYE and drive shaft. It is a rubi/ I will get a longer rear when I get it lifted.

You will need a double cardan rear shaft, I have a 3" lift and I'm on the edge of needing a new driveshaft.
