Bowing rear springs
So I was under my jeep the other day for some routine inspection/maintenance and noticed that my rear springs are slightly bowed. I have RK 2.5" triple rates and was wondering if that's normal? The springs aren't rubbing against anything. I still have stock control arms and stock drive shafts for now. I am wanting to order and install new DS's and rear upper control arms to fix my pinion angle asap but was thinking that the rear ca's would tilt the spring perches more causing the bow to be worse if I understand correctly? And rear lowers would need to be shorter than stock causing same problem? Please help and clarify this issue before I start throwing money at it that's not needed
and not fix the issue. Any recommendations would be greatly appreciated!!!

I believe so. They have the isolators on top of them too! I've jacked up jeep and unbolted axles slightly to help lower to rotate springs to make sure they are seated properly. They don't seat right any other way.

Thanks guys for ur responses!! I'm not a fan of the correction wedges so I think replacing the perches is my solution. I don't have a welder or the know how so I would have to pay for someone to install, which I'm fine with, or I seen that JKS and Clayton make adjustable ones that bolt to axle. Is there any pro/con going that route??

Coil perches are one of those things that should really be welded on. The Artec setup is nice as it allows for some adjustment for stretch.
If you get up in the Detroit area, we'd be happy to swap the perches for you. We also sell those perches if you want to have them installed locally.
If it is a regular shop, it may be pricey to have the work done. It is a bit time consuming by the time you get at everything, cut the old perches out and weld the new in. They don't need a ton of heat, so if you know someone with a 140 amp box that is portable, then you could have everything ready.
That all said, some amount of coil bow is normal and it will not impact ride quality or travel.

Your coils are not at all bad. Not enough bow to worry about running wedges. Its when you move the axle back and correct pinion the coils look like S's (see youtube vid posted above)
I would just install wedges and call it a day.
