I am about to pull the trigger on a 2001 Cherokee. I haven't had a Jeep in over a decade, so I wanted to get some feedback from you guys first. Is there anything I should be concerned about? How much do you think this would be worth?

A throttle body spacer on a XJ is a complete waste of hard earned money.. Spacers work on throttle body injected vehicle and the XJ is multiport injected,,, MPI. Meaning instead of the fuel spraying directly into the throttle body it is sprayed through multiple injectors directly into the intake manifold. .
A spacer helps a TBI vehicles by increasing the amount of air inside the intake manifold that the fuel has to mix with,( more air = more power).
Since the injectors on a XJ are located right at the ports for the head,,a spacer will not increase airflow..
Also its a 01..with Cali emissions,,, Yuck,, you should also look up 0331 head crack for the 2001 cherokees

Does the throttle body spacer have any adverse effects on an XJ (other than wasting money)?

Also the radiator was replaced and an auxiliary automatic transmission cooler was installed. If I understand it correctly, this should help prevent over-heating which seems to be the leading cause of head cracking?
Thanks for point out the CA emissions. Luckily Wyoming does not require emission testing. If i were to license elsewhere, would I likely need to replace all 4 O2 sensors then?

Would you mind elaborating a bit on this? Thanks!

The engine was replaced 3 years ago. Will the 0331 head crack still be an issue?

As for the spacer...NO its just a waste..
Yes a new radiator is good.. Not good to over heat a XJ.
As for emissions,,just because you don't get tested should not keep you from keeping/having good O2 sensors(Helps it run better you know lol)
But if the O2's aren't bad why would you need to change them if you move?
As for the revolver shackles,, From what I have read (no first hand experience) there is a unloading effect or something along those lines that makes them unpredictable. Allowing the body to get away and possibly put you into a roll situation.

Revolver shackles are a gimmick. They look interesting on paper, but they're unpredictable and dangerous offroad. A cursory internet search would've provided that info before buying them.
Throttle body spacers, as Duma explained, are a complete waste of money on a multi-point fuel injected vehicle. More ignorant purchases.
The engine was likely replaced due to a cracked head. If they put the same 0331 casting head on there, the new motor doesn't mean anything. If it's a better casting, that's a big plus.
But I still wouldn't trust any vehicle from that owner.

Oh, more:
The vehicle is 16 years old. If the radiator wasn't replaced, it's due anyway. The XJ radiator is hardly adequate, and age doesn't help them. The aux trans cooler is a big plus, but it won't help with coolant temp (which is what cracks the head).
And the O2 sensors... I had an '01. It needed all four of them replaced, and I was getting 6mpg with the bad sensors.

Agreed. OP is asking us to make an informed decision off of very little text...pics would help. Value is subjective. Depends on where you live, price will vary greatly location to location. The advice given, based off what was provided has been spot on so far.

The what I suspect are not overload leafs in the rear but AAL are not the best choice either for a lift you really want a full leaf pack. The shackles are junk also and I would never run them either. They seemed to have cheapen out in some areas of the build from what little you posted.

Don't be scared off by the CA emissions. It just means a y down pipe and a couple extra O2 sensors. I'm running an '01 with CA emissions (I think all 01's were CA emissions, fwiw) and still on stock exhaust to the cat. Runs fine.
The head is something to be aware, of honestly, most people who make a big deal about the 0331 head are guys that have never run one. Still on the stock head and going strong. Just need to make sure to keep the temp down. Hood louvres are a good idea for those on the original head.
Having said that, if I was springing for something with a new motor, I would for damn sure check to make sure they had not simply slapped the old head on. Get what you are paying for!

And hood vents don't lower the coolant temperature, which is what causes the 0331 to crack. Yes, the engine bay gets hot. But if it ever matches the coolant temperature at operation, something besides your hood needs to be fixed. Ambient air, despite feeling hot when you open the hood, doesn't crack heads.

I bought my 2000 new. I never once had it over heat on me. I kept the radiator clean and flushed with regular maintenance, the head still cracked. So just keep the temp down is not true..
Yes there are many guys running around still with 0331 head and that's great. But when dealing with the 0331 head you are playing the lottery you might win the crack or you might not..
I won mine.yahoooooo!! lol
