Yes, the angles of the A-arms play a role, but I don't think they play as significant a role as you seem to think or imply. IOW, the difference between the "X" and "Y" lengths in your picture don't change significantly enough to matter or be noticable. Say our A-arms are 12" long ("X") and are horizontal at stock ride height. Now add 2" of lift from cranking or spacers. Your "Y" length is now 11.83", which is only a 1.5% change in length. 3" would be 11.62" or 3.2%. Not significant, IMO.


Yes but the A-arms aren't horizontal at stock ride height, they're angled already. Since the change in the length of the lever arm is not a linear function of vertical height (it's a circular function), the "Y" length will change much more as the vehicle is lifted.

I think the fact that you are moving the suspension very close to the droop bumpstops and therefore hitting them all the time is the primary reason for the perceived stiffer/firmer/rougher ride.


This, may very well be true, but don't a lot of people who crank the tbars also use low profile bumpstops?

If you have to ask about a SAS, you're not ready for it.
