XJ Cherokee Heavy Duty Steering Kit

If you are unfamiliar with the WJ knuckle swap it entails swapping the stock knuckles to knuckles from a 99-04 Jeep Grand Cherokee. There are not many steering upgrades out there for the XJ Cherokee, and this allows for a heavy duty steering upgrade and a big break upgrade! Here at Core 4x4 we are putting together a full seamless kit that is ready to go for you, instead of having to piece together a kit from either a junkyard or different parts from different people.

This is awesome that you have come out with a complete kit, totally worth the price vs. using rusty junkyard parts and headaches of figuring out the steering setup.

[@SuperDad1776]

Can hardly wait for this kit to come out! My lady’s XJ badly needs the upgrade! Well worth the buy rather than the junkyard method! Keep up the great work guys!

[@core4x4fab]

Thank you! We will announce when it is available! We are making final adjustments to make sure the kit is good to go!

[@SuperDad1776]

@@core4x4fab fantastic! Looking forward to it

[@paulstandaert5709]

Now, what about sway bar mounts?

[@theviper6602]

I use aluminum flat stock clamped to the axle tube it pulls the heat out of the axle 😊

[@core4x4fab]

@theviper6602 that's an awesome idea, I like it

[@theviper6602]

@core4x4fab welder for 20 years I've learned the hard way couple of times and ruined couple axles haha I have some ideas for xj would like to pick your mind and Maybe we can come up with some new products if you want my contact info let me know

[@m2hi2cu33]

I m a little worried that you didn't weld the spacers to the knuckles...if you look the hub only seats in the knuckle about a quarter inch and you need that secure, otherwise the bolts are the only thing holding on hub, brakes and larger tires. and a tip for the tapered slugs is put a tack weld to hold for disassembly later or they may come out with tie rod end

[@flyguyeddy]

Seems like most people only do 1" welds on the spacer, i dont imagine thats all THAT strong. What about just using grade8 bolts?

[@1unkn0wn]

When I first read that Iron Rock Offroad lists their spacers as "bolt on" I was also a bit hesitant... that is until I did plugged the clamping force into a calculation. 3x 12mm grade 10.8 bolts (assuming the grade, could be upgraded) have a combined clamping force of thirty three thousand pounds.

[@craigwood3498]

Excellent thanks I have a XJ , MJ and TJ this will help all of them 👍

[@Kevin---kx3jy]

That hub spacer is carrying the load of the hub/unit bearing. It should be welded to the knuckle.

[@1unkn0wn]

Have you ever calculated the clamping force of those bolts? It's frigging crazy...

[@cody2097]

Bumpsteer; its gotta be pretty bad considering how short your track bar is. Being parallel is a big part but length is important too. Is there an option to mount the track bar in front of the coil to get the length closer to the same as the draglink?

[@TristinWilliams43]

I don’t see this kit listed under the Xj

[@bspizzledizzle]

Do you know if this kit works with a rubicon express track bar bracket? My current set up has a frame brace that I would really like to keep.

[@AB714AA]

Do you sell just the trackbar bracket orange one?

[@kevinclevenger8741]

I really like the kit looks really will built. Iam running your short arms on my wj with 8 inch lift and the wife's wj has 4inch lift with your short arms. So now we are waiting to see if you come out with a long arm kit for the wj .

[@core4x4fab]

Glad you’re loving the products on your vehicle! Thank you for your business. We aim to make this kit top quality and easy to use with everything you need. We are finalizing products and design and should have it available on our site shortly!

[@emtjc1986]

going to buy this kit. My only question is about the new track bar? why is it mounted with the bend facing up? Aren't you worried it will hit the oil pan at full compression, and can you mount it pointing down?

[@core4x4fab]

Good question! The slight bend is for the diff cover clearance. At full compression at this height there is ample room above the track bar.

[@emtjc1986]

Thank you for the reply. I just placed my order yesterday. Can't wait to get this on the Jeep.@@core4x4fab

[@doers8154]

Hello there! will this kit clear 15 inch rims with 3.75 back spacing???

[@brianprzysiecki4704]

We’re did you get the bushing inserts for the knuckles? I did this swap and mine seem thinner and don’t weld in

[@philipjackson4200]

Can you get ball joints with knurling?

[@philipjackson4200]

Is the unibody side track bar bracket compatible with frame stiffeners?

[@Mickale-Moranis]

Since the XJ front is basically a TJ front, this should work just as well on that platform. I use a XJ front in my TJs due to using adjustable (1 TJ) Core4x4 control arms (way to align caster, XJ is off frame, TJ is off axle bracket), and high pinion layout. Another thought, since the WJ knuckle is a high steer drag link, was there ever a RHD WJ? Cause, similarly, the JK knuckles are mirror to the WJ and JKs had RHD so that, you could relatively due a high steer setup (over the knuckle) on the drag link and then tie that to a high steer (another over the knuckle) tie rod, but using a bracket to make it even higher between the 2 steering points on the knuckle. Since you added a 'decorative' plate on the front corner, too bad didn't add a skid plate to the lower CA axle brackets and the upper passenger. Lowers tend to rip off or tear off. Upper CA bracket tends to fold or tear off the tube.

[@warbanzi]

Ball park price?

[@jmangus83]

I don't even see this steering listed under the jeep xj. Also regarding your tier 4 long arm kit, there are no details. What is the thickness of plate used for the cross member? I assume the center section is removable to allow servicing trans etc without taking off the arms. Can the cross member work with frame stiffeners that are already installed? Does the tier 4 kit come with Johnny joints to replace the pressed in bushings on the axle side? Are the arms designed for high clearance? What is the minimum lift height for your long arm kit to ensure no contact upon up travel? How is the clearance of your cross member? How low does it hang below the bottom of the frame rails? Do you guys offer a skid plate that will integrate with the cross member or plan too? I'm in the market for a 4 link lift and I can't find much if any info on your guys kit.

[@core4x4fab]

Hey Jon, thanks for the questions! The plate is all 1/4 inch on the brackets and the crossmember. The crossmember itself is two separate 1/4 inch plates welded together, so in most places there is 1/2 inch of steel between you and the ground. The kit can work with frame stiffeners, we slotted the frame brackets to allow for that. You will need to clearance a little more on the inside of your frame rail though. This kit does really well on LCG builds and we have had customers run it on as little as 2 inches of lift. There may be more trimming around your factory upper mounts for clearance on the arms, but generally the range of motion is there. Currently there is not a skid plate for the transfer case, but we are looking to add one to this kit. The crossmember itself has really good clearance and was designed as a "high clearance" kit.

I am interested in this kit. I do not see a link on your site for it. Also, what are the TREs and rotors from? I assume they are OEM for something, would like to know that I can go down to the local parts store and get replacements when they wear out. Thanks!

[@core4x4fab]

It is not yet available on our site, we are making minor adjustments to make sure the kit is ready to go! We will announce when it is available. We get our Tire Rod ends from either Rare parts inc :)

@@core4x4fab My question was not where you source your TREs and rotors, it was where I can source replacements when they wear out. I've had the jeep 10 years now and plan to have it another 10. I do not want to install wear items that are custom order. Are they OEM from another vehicle or custom?

Iron rock offroad sells theirs as bolt ons. IF the bolts are 10.8 grade and IF I understand the calculations correctly that's just under thirty three thousand pounds of clamping force....
