springs vs. shocks

hi guys, first post on here. I browsed around for a bit and didn't see an answer for my question so here goes.
I have an 06 LJ that has a 4 inch lift currie/savvy suspension with the silver bodied rancho (9000 i think) shocks. uses rock jock springs. I have installed some metalcloak steel corner guards and fenders and now I'm saggy in the rear and bottom out way more than I used to when running rougher terrain.
I called currie and asked if a stiffer spring was available and he said that it prolly isn't the spring, and it is most likely the shock. Now, to me this seems counter-intuitive....but what do i know. can someone help me out. i dont want to waste money where I don't need it.
also, I did notice that from over extention, the rear lower spring cups have made a small dent in the shock body. not sure if that would make the shocks go bad, and I can post a pic if someone really needs to see but they are small. please let me know your thoughts guys. thanks, pinwormfood.

Seems like an odd response from Currie. Springs set the ride height. Shocks control the movement. If you added weight causing the rear to sag, then you need longer/stiffer springs to raise it back up.

Springs do generally set ride height and shocks should control ride as stated previously. Is your rig lower in the back than the front now, or just lower than it was?

If the rear level or higher than the front with a load than I would not see it as a spring issue. A good set of tuned shocks would be where I would be looking in that case.

If the rear sets lower than the front I would then replace the springs with an HD version.

Perhaps because you said "bottom out way more than I used to" they focused on your shocks. Stiffer shocks would help that, but it sounds like you really need stiffer springs to get your ride height back.

I thought Currie made 4'' lift springs and HD 4'' lift springs for heavy jeeps. I would try giving the guys at Savvy off road a call, they helped me out with my questions with my setup.

I have the 4" +.5 Currie springs in my rear and they did raise my jeep to where I like it. From what I recall when speaking with Currie about it the spring rate is not more HD, just a taller spring. Anyone please correct me if they know otherwise. I don't have any rear corner armor, but do have steel skids.

This. If you listen to Rancho's lift height recommendations you end up with shocks that are too long and have limited up travel.
