I will probly run these after my axle swap but I am wondering if the stock bracket will work. I have heard conflicting stories.

Holy cow, that would be great if they were compatible. How did you hear of this?

I would love to have 2 or more piston calipers on my ZJ.

WJ or WK, either way...I would enjoy an improvment on the calipers. Looking forward to the write up.

I just saw a write up on this a few nights ago. It's for an XJ, but should be the same. Here it is:

yep, that is what i will be doing...i have all the parts sitting in my garage. all in all it cost just a shade more than doing currie steering, and i get a brake upgrade.

parts:
dom steering links - kevins offroad $150
knuckle spacers - kevins offroad $25
tie rod end - $150
wj calipers and knuckles - bone yard $75
rotors - 98 ford explorer sport - $50
Total: $450 - maybe $90 more than a currie setup

I've run WJ knuckles + brakes on an HP30 on a TJ, it works out well. Don't be a ghetto idiot and use washers instead of the knuckle spacers like I once saw a jackass do: all the vehicle weight was riding on the 3 hub bolts that way...

jsteves

already have the spacers welded on...that is about all that is done.

oops yeah WK is the code for the one they ship overseas. WJ is what I meant. I am getting a couple sets in this weekend. Will post some pics

Thats not what Chrysler says but who cares....Hey these calipers were like $90 a pop....man this build is getting spendy!

What? WK is the latest model grand Cherokee, period...

93-98 = ZJ, 99-2004 = WJ, 2005+ = WK, regardless of export.

I thought MC is advanced Grand Tech... we should at least get the body codes right. haha

93-98 = ZJ (export ZG)
99-04 = WJ (export WG)
05+ = WK (export WH)

I beleive europes version of our WJ is the WG. WK is the new grand, 2005+.

Should you go ahead and get the updated version of the calipers for the 2002+ WJ's? There was warping on the earlier models. Just a thought.

that is true, however, i got the early ones becuase they will fit inside my 15" wheel with a little bit of grinding, but the later ones won't fit.

if i have problems, i will spend another $25 at the bone yard and buy some new wheels.

16" blacky's are cheap though. You can even get some beat up MOAB's for cheap now if you do not need the BS.

Do not use the WJ TRE at the Pitman. I choose to change it all to 3/4 ton to gain more flex.

here is a start of a write up on the conversion.

http://www.ruyellow.com/WJ-SteeringCobraBrakes.htm

Here you can see the small amount that the WJ TRE allows for droop on the Pitman.

Here you can see the Chevy 2026R TRE allows for 60 Degrees of motion.(or 30 Deg of droop)

As you can see in my writeup, only $200.00 for new loaded calipers.

That was about 1/2 what I thought they would have been.

jsteves
02-21-2006, 08:57 PM
yeah, but i paid 25 for a couple from the bone yard that had almost brand new pads on 'em

nice tip on the TRE's!

are they the same thread as the wj TRE?

RUYellow
02-21-2006, 10:29 PM
No, they are 7/8 18 tpi.

The beauty of the combo of the WJ Knuckles and the 3/4 ton TRE's is that you can have the much touted "one ton" steering, but better.

You do not run the draglink into a spot on the 2233L that is prone to bending when under a lot of force, it goes straight to the knuckle.

Don't forget that you will need to relocate your Trackbar to be parallel to your draglink. So it will need to be mounted on top of the axle. You also need to relocate the Steering Stabilizer.

If someone is just looking for the brake upgrade and doesn't need the steering upgrade, I think that the stock ZJ inverted Y would work in the WJ knuckles and you would not need to mess with the trackbar.

You could then upgrade the steering at a later date, and the extra mounting point on the Steering knuckle would already be there.

Those cobra calipers have the same mount pattern as the WJ? Any other calipers that are the same mount?

You will have bumpsteer, let us know how bad it is, but you will have it.

Yes they do, I am using Ford Sport Trac rotors, so I do not know how they would work with all WJ stuff, but this combo is fine.

Sorry, the only ones I checked are the Cobra, and that is because I saw a post from Chris_L on JU way back when.

My braking is OK, just looking for other options. I'll have to see if these or others will work with ZJ knuckles.


Thanks.

The problem with ZJ knuckles is that the brake brackets are cast into them. Then the calipers just slide into the knuckles.

On a WJ there are just 2 bolt holes that you can mount any bracket that lines up.

If you do this you will need to have the brackets and the calipers.

FWIW.....The Guy that did this write up has a pair of WJ calipers for sale in Orange County Ca. (email mjr@gotgroceries.net )

What? WK is the latest model grand Cherokee, period...

93-98 = ZJ, 99-2004 = WJ, 2005+ = WK, regardless of export.

93-98 = ZJ
93-98 Export = ZG
99-04 = WJ
99-04 Export = WG
05-current = WK
05-current Export = WH

Oh and in case anyone was curious the Grand based Commander.

06-current = XK
06-current Export = XH

Yup. I did a few things differently since I wrote that (need to do an update). I am using the WJ tie rod ends flipped up top like RUYellow but the drag link I have at the pitman arm the WJ LHD rod end and at the knuckle I have a RHD rod end (bent the other way for use on top). All I can say is the WJ brakes in front, Explorer brakes in the rear, WJ master/booster, and prop valve mods make my XJ stop like no other including stock ones. Mind you I have the extra weight of the 4 wheeling stuff and 35's.
