Riddle me this (control arms)

[HobbyPoor]

In the process of installing my lift kit I notice the higher the Body and Frame of the vehicle goes the further back the spring seats on the axle are compared to the upper spring seats....

It seems the spring would be riding in a slight bend the whole time you're driving it... And would decrease your articulation during off-road maneuvers... Shouldn't a longer lower control arm and possibly a longer upper control arm be in the mix. Does any aftermarket Solutions cure this or am I overthinking the situation... it just seems a longer control arm the higher you go would be needed and would reset everything to the original plane of travel

Thoughts?

While it doesn't effect articulation, the rear frame side spring seats are angled in a manner that as you lift the vehicle and rotate the pinion angle upward for a SYE the spring mounts get out of alignment. It isn't an issue until it gets to the point where your bump stops no longer make contact due to the angles they are pointed.

At 4" of lift and a tummy tuck this became a problem for me.

I checked and the replacement arms are about a half an inch longer than the stock ones... Just seems they should be a little more than this to make things line up correctly

Are these fixed length arms or adjustable?
