Help with Dad's Rough Suspension

My dad has a '07 JK 2dr that he had a "guy he knows" put a spacer lift (don't know height) on and use stock shocks w/o adapters from what I can tell. He does not know the specific details about it. I told him he needs to find out in order to help determine the right course of action.

Anyways, his jeep seems to ride pretty rough. A local shop said he just needs longer shocks, that the stock shocks are maxed out and not allowing them to work properly.

I took a couple of pics. Pic quality isn't great (phone camera) and for the life of me I can't get them to rotate...sorry.

What do ya'll think is the problem or do you have ideas of what it might be and how to fix it.

How many miles on the Jeep? Average(ISH) life of shocks is 50,000 or so.

I am pretty sure he has less than 50,000 miles on it.

It may be worn out shocks, but I am skeptic of it being that simple. I think it may be that his stock shocks aren't long enough, but not sure.

Measure the spacers. It's either going to be a smaller leveling kit or a budget boost.

#1 shocks x2 on the 9000's. take advantage of Rancho's currant rebate,
Remember. I don't see bumpstop extensions ?
Def needed to run a longer shock if chosen.

#2 swaybar links
The rears can be used in the front because they are longer. Al that's needed now are longer rears.

Jeep should ride 10x better

Are those new tires too? If so, check the psi. Should be below 35 psi depending on the tire.

First off all things are equal. Same shocks, same springs. Ride quality should be EXACTLY the same as before the spacers were added. I see no rear bumpstop extensions so there should be nothing contacting.
There are 3 components that make a stiff ride:
Heavy springs
Stiff shocks
Too much air or e rated tires or both.

So since you have the same shocks and the same springs that leaves only one thing.

The Factory shocks are not too short with simple spring spacers unless you want to flex it out. You certainly won't bottom them out, you can only stretch them to max. Jack up the back and you'll find he still has more stretch on those shocks then he'll need on the road. Again that doesn't affect the on road ride.
Another NOTE: shocks DON'T carry weight they slow down and smooth out the motion of the springs.

E rated 35" tire should be around 26-28psi for a 2 dr.

I does appear that this is not a very complete spacer lift as he still has the factory swaybar links and no bumpstop extensions. Didn't notice if it had a rear trackbar relocation bracket.
Edit: just checked photos it does have a reloc bracket.
