I entered those arm length and frame/hub distance numbers in the website and got completely
different results. What am I missing? Here's what I got with horizontal, and 3 inches (76mm)
down and up:

For what it's worth, our coach handles great with the one ton front end, even with a
really sloppy attempt at alignment. It was terrifying to drive before, now it's not.

confusedly,

> I went to the website and entered the dimensions for the 1 Ton upgrade using these numbers:
> Lower control arm length 14.75" or 375mm
> Upper control arm length 9.75" or 248mm
> Distance between mounting points on HUB 11" or 279mm
> Distance between mounting points on chassis 9" or 229mm

> The upper control arm is angled up 12.75 degrees when the

> The camber angle has a huge change from - 5 degrees to
> +2.5 degrees when moving 3 inches up to 3 inches down.
> That's 7.5 degrees of camber change
