Don't put lifts on it, it will put premature wear on the bearings and drive shaft. Transmissions aren't meant to work at an angle, so you'll have problems with that too.

Stock XJ's do amazing without lift. Just make sure you have good suspension and lockers and you'll be set for trails.

>premature wear on the bearings and drive shaft. Transmissions aren't supposed to work at an angle
What the hell are you talking about? Shim the rear axle and none of that changes. No bearings have ANY additional wear on them. The transmission angle stays exactly the same, and the drive shaft is a metal tube which literally cannot get worn out.
If transmissions aren't designed to work at an angle like you say, how can vehicles go up / down hills without failing?

Premature failures occur when you lift and don't get an alignment / shim the rear axle. For an '00 XJ, lifting over 2 - 3" will require a SYE and a double cardan rear shaft. Might as well get adjustable control arms for the front, and an extended brake line for the rear axle.

Removing the leaf springs? Those are your entire rear suspension. You can't just remove them. You can convert to four-link but it requires extensive fabrication work that you don't know how to do if you are asking questions like that.

Also, what do you mean by a "frame support"?
Xj's don't have a separate frame, they're unibody.

Does it still have the 0331 head, or did they replace it when the motor was rebuilt?

>>17674601
I'm going to be doing some overlanding with my XJ. The trails I take it on will demand ground clearance. I'm going to be replacing the rear axle with an 8.8 Just because my best friend and his dad have done 3 swaps using the 8.8 and know exactly how it goes, and the front with a 44.

I'm not too sure, I never thought of removing the rear leaf springs, but my best buddy did it on his XJ.

I didn't mean to put frame support, my bad, I meant rock sliders.

It's still the 0331 pre cat. The previous owner blew a head gasket, so the guy I'm buying it off of did an entire rebuild.

Your best buddy either converted to rear coils (which would be a 4 link setup) or he's full of shit, because you can't just "remove" the leafs.

The previous owner most likely didn't blow the head gasket. The 0331 head likely cracked. Which is why I asked. If you don't know of that issue, then a cracked head can seem like a blown head gasket, although it isn't. This only applies to 00-01's, because 99 and older had better head castings.
They made an 0331 head which fixed this issue, but it was only on TJs and possibly WJs. That head is often called an 0331 TUPY head.

r u habibi?

>>17674650
Although XJ's are unibody, you can still stiffen the frame rails with supports to make them less prone to flexing, which is an issue with early unibody designs (ie, XJ's and old mustangs)

>>17675040
Sure, i know that frame stiffeners exist, but a stock XJ has no reason to have them. Unless the unibody is rusted / damaged, it's plenty strong enough for stock applications.

Like OP said, he's going to do some overlanding/rock crawling, so not really stock application.

>>17675059
fdo

>>17675078
No, but the truck is bone stock right now. We're arguing semantics, considering it doesn't even have stiffeners. OP mistyped when he meant side steps.

Are wheel spacers worth it?
