Coil Springs or Shocks?!

So i have a 3.5" lifted '96 XJ on 31" tires with no added body armor/major sources of weight. I put this lift on about 3 years ago and recently the front passenger is starting to sag causing it to be off-level across the hood. I have read a ton of posts and still am not clear. I need it to be .5" higher on the passenger front. I have an add a leaf kit in the back (with 4 leafs- i have seen some people ask in other posts if it matters) & Rancho 5000's in the front with Rusty's 3.5" lift coils (I didn't know any better at 16- i get it now )

Measurements: I measured between the e's in Jeep (the middle of the wheel) on stock rims to the bottom of the fender flare- uncut/unmolested

Front:
Driver- 21.25"
Passenger- 20.75"

Rear:
Driver-22.75"
Passenger-22.75"

Basically i am wanting to get this back to level and i don't know if i can just add a .5" spacer to one side (Being suspension this seemed unlikely) OR if i need new coil springs OR if the source of my problem is just a bad shock.

- I have checked all of the parts in question & none are visibly damaged. No spring spacers at all so far so nothing got shifted/moved. The shocks "feel" even when adding my roommates body weight to either side and measuring travel (~2-3's depending on if he sat or i tossed him onto the hood- appx 175lbs). I was measuring travel from the bottom of the respective side of the plastic bumper cap to the pavement. That to me pointed to the coil but the "Honda Expert" roommate swears its the shock. Help!?! Much appreciated

Having the jeep lean to the passenger side is normal. Usually if it is leaning a lot (> 0.5") it is the leaf springs sagging. I had to battle the same issue and it turned out I had damaged the passenger side leaf spring.

Hey thanks for your reply! I had read that in a few threads but was not sure if they (The leaf springs) could be damaged if the rear sits level? If so, how would i check to make sure its the leafs or that one is damaged as they are sitting at the same height? IF it is my rear leaf's, would a new set take care of the problem or just prevent it from coming back for a few months until the new leafs settled? More or less i want the dang thing level & don't mind doing the wrench work/buying the parts- i just dont wan't to have to re-do it all every few months to chase an impossible goal. Again- thanks!

It's not the shocks making it sag. Shocks have nothing to do with ride height. Shocks absorb the oscillations from your springs. If your ride is really bouncy better quality shocks and springs would fix that. If I were you I would replace the front coil springs, that will make your ride height level, I would also replace the rear add a leaf with a full spring pack, from my experience if your add a leaf hasn't started sagging yet it eventually will

That was my origional thought- do you reccomend any particular brand (Other than Rusty's- i won't buy ANYTHING with their name on it) that is known for lasting longer/not sagging or at least sagging at the same rate? And i was incorrect in my origional posting.

** As far as the rear goes I have a full spring pack meant for a lift-kit and had been calling it an add a leaf (I assumed anythign with more metal than stock was an AAL but got it figured out).
