Up country sway bar

[Atl XJ]

Can you run the upcountry front sway bar on a stock suspension XJ? I was thinking this would be a cheap way to to improve handling if it would would work.

 

[rsalemi]

yes & Yes - Some Limiteds had a 1 1/8" front bar - bolts right on with energy suspension poly bushings

I don't think the up-country package came with a larger swaybar. You want to search the junkyards for a limited, or any other XJ you find, with a 28mm front bar. Did that myself this weekend and got one at the pull-n-save for $10. It'll be going into my XJ this coming weekend.

Anybody want a slightly used, 26mm front swaybar from an '01 XJ?

 

[Atl XJ]

I thought it came with a larger front sway bar since they dont have a rear sway bar?

They don't need a rear swaybar because the rear springs are stiffer. I know the Limiteds came with the 28mm swaybar, but I'm not sure about the Up-Country package. I would suggest getting a cheap caliper (if you don't already have one), something like this...

Then go to the junkyard and start measuring. That's what I did and the third XJ I looked at had the 28mm bar.

What year did they start using the 28 MM? I got an 89 that didn't have one.

I definitely have an oddball XJ but maybe that's because it's an export model. I have all the UpCountry goodies plus the 28mm front antisway bar AND a rear antisway bar. I installed poly bushings on both antisway bars and the difference they made to the handling was incredible. Since my Jeep also has poly bushings on both sets of front control arms, it corners like it's on rails. The only downside is that the ride is harder and I can feel more road imperfections through the suspension.

My 89 upcountry had a 28mm sway bar, but no rear bar.

i have a 98 classic. anyone know the size sway bar i have?

 

[incubi67]

well i measured it. its 27 mm and the rear is 16 mm. so its not worth me buying a 28mm. i'm just gunna get some poly bushings.

 

[dmillion]

27mm!?! I didn't know they even made a 27mm swaybar. So, I guess they made pretty much everything... 24, 25, 26, 27, 28.

 

[frankenjeep]

mine measured at 26 mm

 

[bajacalal]

I know it was a while ago but I wonder if you accounted for the 1mm of mud on your sway bar.

For an accurate measurement, you have to do it at or very near the uniframe attachments. I completely took mine off to get an accurate measurement, as the number varied from one location to another (albeit by fractions of a mm.).
