Just swapped out mine...the local 4X4 transmission guy around here says that the Luk or Luk Gold kits are a good clutch for the money. You can go upscale & get a dual-friction Centerforce unit for double the $$$....they do hold more HP, but if yours is a stock 4.2, that might be overkill.

Either way, it's good sense to resurface the flywheel & replace the slave cylinder/release bearing while you're in there.

Make sure the kit comes with an internal control unit. X2 on the master slave cylinder and bearings too. Most kits come with everything except the master slave, but it's good to check what components are in the kit. Also, if your hose line from the master to the internal unit is bad an oem line goes for between 190 and 200 $. They don't make an aftermarket for your 89 4.2 AX 15. Ask me how I know. You might be able to rig something else though. Maybe someone will mention how to do it without spending all that $. Plus, bleeding the air out of the system is a pia. If you don't use a bleeder it will take forever and you still might not get it all. The system design on these suck. A reverse bleed works the best. Good luck.
