Some would opine that the "need" to correct the angle of the RA in order to optimize and return suspension kinematics to the stock design happens well before 4.5" of lift. In dissecting the language that Lewis Built used in their add, they are simply saying that an appropriate/OEM caster angle can be achieved with lifts up to 4.5" because their upper link is adjustable. Without dropping RA mount, the angle of the RA is steepened, brake anti-dive is increased, and suspension compliance is decreased. How much will it really affect performance? Are we splitting hairs? Carli seems to think that dropping the mounts is more important than replacing the RAs, as they are an option in 4.5" kits.
I kind of look at it like this: Ford probably was very specific in designing the stock front suspension. The further we deviate from those angles can only serve to compromise ride, handling, and braking.

That's true but damn 1800 dollars to run Carli RA. Cause the RA is around 1350 and then apparently to run them you need their drop arm brackets as well which is another 475. And with PMF adjustable 3 arm link that's all I need for 900 dollars. Now I'm leaning more towards PMF and I've heard nothing but good results out of their RA.
