Replace front springs?

[thewhitestallion]

I have a 2014 Sierra z71 4x4 and I have had a rough country leveling kit on it since about the 8k mile mark. I now have 110k and the front end is still doing great minus the crappy rancho shocks. I just put the 5100's on the rear a few months ago and man the ride difference is HUGE! I wish I would have done it sooner! I am wanting to replace the front ones soon as well but am contemplating getting new springs since you gotta disassemble the whole thing anyways. 

 

What some of yalls opinions on replacing the springs? I know springs wear out and began to "sag" a little and I'm sure the springs are ok right now but will they be in 2-3 years when I still have the truck and it has 150k on them? 

 

Basically I dont want the springs to cause the shocks to work harder and wear them out faster. Also should I get factory springs or aftermarket springs that level out the truck and take out the rough country leveling kit?

Can't really comment on the springs, but if you are going to do the 5100's on the front I'd definitely remove the RC leveling kit.

This is why most instructions say to measure your truck before and after install of lift/lower kit as well as after a few miles. Say it is 35" then years down the road it is 34" And you don't like it. Well on some kits there are spacer rings in 1/2" amounts. My rear has removed over load spring so there is a Air Bag. Saves the life of the suspension. I think all trucks should have helper bags in my opinion.
