I've searched and cant find anything on people using the ZJ 4.0 fan blade along with the fan clutch on an XJ. Seems to be a simple upgrade with 2 extra blades to get more air flow.
It is plug and play, just be careful of the clearance between the front of the clutch and radiator.
94 XJ w/ 4.7 stoker, 97-98 ZJ HD 4.0 fan clutch
Trying to get some more airflow across the rad to help stabilize engine temps. Gone trough the entire cooling, ignition, and fuel system and this engine runs hot (220 no a/c) normal freeway driving.
ZJ HD fan clutch is drop-in replacement. HD so I think its the V8 clutch not the 4.0 clutch. Basically it just comes on earlier / goes off later. I found it overcooled my old motor.

It also has less slippage built into it. Dont emember the fact percentage but it is noticeable.
I personally didnt like it. Made more noise with a noticeable decrease in mileage without much improvement in cooling.
I recommend the op service their cooling system first before you start throwing fans at it.
