TJ Steering upgrade?

Hey everyone,
I'm starting to look into upgrading the steering system in my 97 TJ SE 4cyl Auto, it has a 2" BDS suspension lift and 31" tires, looking to upgrade to 33" soon. Is this upgrade worth it?
I've read some people replace steering components with stock Grand Cherokees? Are they direct fit? What year grand cherokee would I need to be looking at? What components would I be replacing? Part numbers for ease of purchase?
As you can see, lots of questions lol and I haven't found the perfect write up for this yet so if anyone is aware of one please link it. Thanks for any advise.

The ZJ upgrade is well worth it.

Do a search for ZJ tierod and you'll get your answers. It is a good upgradeunless you play in the rocks pretty hard. The ZJ tierod is a solid bar whereas the TJ is a hollow one and will fold very easily if hit. I swapped in a ZJ tie rod and bent it twice in a span of a couple of months playing in the rocks. If you have plans to rock crawl, I would suggest going straight to the Currie HD steering.

Yup, I just did the ZJ tie rod upgrade, well worth it. About $100 from the auto parts store.

I did the ZJ upgrade on mine. I used a post by Holton345 to get my parts. He listed the Moog part numbers and I ordered them off of Rock Auto. You can use 93-98 Grand Cherokee, or I just clicked on search by manufacturer, selected Moog and typed in the part numbers. Here's what he had listed:

ZJ Front End Parts

1 - DS1310 - right side, outer tie-rod (This is what we call the drag link.)
1 - DS1312 - left side, inner tie-rod (This is what we call the tie rod.)
2 - ES3096L - Left hand thread tie-rod end (One of these is needed for the end of both the above parts.)
1 - ES2079S - Tie Rod End Adjustment Sleeve (I chose to get two of these.)

From this thread:

https://www.wranglerforum.com/f210/je...n-1044122.html

I think it was $210 or so. It all bolted straight in, but you will need an alignment after. His parts list made it really easy for me to get it ordered.

You don't need to do a full alignment after replacing the tie rod, only the toe-in needs to be set. That is a very easy adjustment to make that with usual care, will produce results literally every bit as accurate as any alignment shop can obtain. The only tools needed include a tape measure, wrench, and a big set of pliers.

I did the upgrade today and it took less than an hour...including the toe in adjustment. Excellent and inexpensive upgrade. I highly recommend you use moog parts so you dont have to do it over again in a few years.

Just be aware the ZJ V8 drag link is not an upgrade only the ZJ V8 tie rod is an upgrade

While the drag links are the same strength TJ vs ZJ V8 the ZJ is somewhat different in its clearance bends and the orientation of the tapered hole for the damper. The ZJ part is a lower price but does not fit as well as the TJ drag link and some have had difficulty with damper binding

Both drag links and the ZJ V8 tie rod use the same adjustment sleeves and short tie rod end

The TJ tie rod and tie rod end are smaller and weaker

I actually had a clearance issue with the tj drag link I just installed and the ome damper, which wasn't an issue with the previous ZJ drag link I had. Just FYI.

The ZJ drag link has a slight bend down at the pitman arm, which seems to level the joint more than the TJ. The TRE at the passenger wheel is still angled up as with the stock TJ link. I have 4 inches of lift so others may see different angles.
The steering damper hole may be slightly off, but I experienced no issues. I have an OME shock and used that mount. That mount did not slide all the way down and is slightly up, giving more clearance at the drag link. I have been with this set up for a while and have had no issues with the damper.
The only slight issue is the ball joint between the drag link and tie rod, which when the steering is turned to the passenger side is slightly up against the axle. The steering bolt may need to be adjusted out a bit; its about a 1/4" off now causing the ball joint to hit first.
