tbh only reason I levelled my truck was to fit 275/65/R20 BFG KO2s on there. my plan was always to add a 3" rear block once I had the time, but I'd rather find out what's causing the sag in the first place. The 3" block is only about $150 anyway and if the cause is really due to worn out springs then I'm not going to bother replacing the springs, just going to put the 3" block in there, I don't tow much anyway.

3 inch block on one side to level out the body and leave the stock 2 inch on the other side? Probably work cosmetically but might not be the best idea.

Nah I would put 3" on both sides, honestly the sagging suspension wasn't noticeable until I leveled it, because then the front was a little higher than the rear and you could tell. Before I leveled it I (or anyone else) didn't even notice the sagging passenger side. If I make the rear higher than the front overall then I don't think it would be as noticeable. When I get back from my university in a month and a half I'm also going to replace my rear shocks altogether. My truck has 73k and I don't know if they've ever been replaced, so that might help a bit.

^This. I'm thinking that OP with the 6.2 has been getting on it and this is the normal progression when you put a lot of torque down with a leaf spring vehicle. Or as mentioned there could be a failure somewhere in the spring.

A competent spring and alignment shop can re-arc the springs and add a leaf, or even replace leaves to keep the height exactly the same...although at around 3/8 of an inch there's not much change. A new factory set of springs would also correct the sag.

i think my first course of action is going to be getting new shocks. Probably would have to replace them soon anyway and I have no idea when/if the shocks have ever been replaced. If that changes nothing I'll probably just add a leaf over the summer.

And no I usually accelerate pretty calmly, although I don't know who had the truck before me. 73k in 4 years means they did likely highway driving.

I'm also considering helper springs as another possible option. They're pretty cheap and seem to work pretty good for people who have a sagging suspension issue.

Resurrection time.

Hey guys. I am experiencing something very similar on my 2013 xlt. I have super springs on mine, but I am still having a sag of 2" on the passenger side over the driver side.
Now I do have a bds leveling kit on the front, but that's about it for mods. I have looked and there doesn't appear to be any cracks in the leaf pack.
Any other ideas on what it could be besides the leaf springs?

Thanks!

I'm having this issue also, RR, on my 2014, with RC 4" lift, it has been getting worse within the last year, I just ordered new shocks hoping this is the problem. the tire is constantly rubbing the plastic inner fender

Is this a common problem?

My 2014 is straight level on both sides thank goodness, but another guy here with a 2014 had the same issue (one rear side was lower than the other side). Once he replaced both spring packs with aftermarket packs his problem was corrected. Not sure anymore which brand he went with, but the aftermarket spring packs corrected the rear end. Might not fix everyone's individual issues, but just letting you know that option fixed this one.
