Hard-KOR Track Bar Conversion: Cures Death Wobble

**Requires minor modification for some stock-height ZJs and XJs and all '84-'86 XJ/MJ**

From the factory the passenger front tire can only droop approximately 8" from stock height due to the upper tie rod end on the factory track bar. Now, subtract the height of YOUR lift from the maximum of 8", and that's how much passenger side droop you have before the tie rod end binds causing wear and then Death Wobble. You can test this yourself if you don't believe me. Just remove the lower bolt on the stock track bar and allow it to hang. Bet you didn't know that! That's the maximum it will go before it binds on itself, which is a future failure in the making! Other track bar manufacturers use Heim joints and Johnny joints in a vertical orientation, which allow the track bar to drop a bit further than stock, but still not as much as you need.

Our track bar gives you superior strength and thickness (.156 wall 1.25" OD tube). The custom interference-fit ultra-thick bushing inserts and the 1/2" Grade 8 hardware in the kit gives 50% more strength than stock bolts so that you can really torque it down without worrying about snapping the bolt off. This gets you a far higher Death Wobble resistance, as the entire kit stiffens up the front suspension.

There are two additional benefits as well: substantial increase in steering response (tighter steering = less wandering) and slightly reduced bump steer, most evident on the taller rigs. For an even GREATER steering response, we highly recommend KOR-1199 SuperDurometer Bushings. Recently, I've had some SUPER-hard Rockwell Durometer bushings made by our poly molding company. You can't get these anywhere else, folks. The stock rubber bushing material that comes in the stock track bars is less than the 45d hardness of the "regular" bushings that we have used over the years. The SUPER-hard bushings are a 75d harness, or 70% stiffer, giving even better resistance to Death Wobble. There is about a 5% change in road mannerisms (when you go over bumps, you'll feel it a little more in the cabin), but it's a low price to pay for what MAY cure your Death Wobble completely.

Imagine a fully adjustable track bar that eliminates the weak/worn stock upper tie rod end on ZJs and XJ/MJs factory track bar and will allow for AMAZING amounts of droop and tighten up your steering responsiveness at the same time. This kit includes a modified upper track bar mount and the highest quality track bar that exists, custom built specifically for me by a top-quality well-known track bar manufacturer to KOR's specific bends and measurements, and fully adjustable to center your front axle perfectly. It won't interfere with any existing suspension components and will allow MAXIMUM articulation from the front axle assembly and a larger resistance to Death Wobble. Designed to work with XJs, MJs, and ZJs from 1" - 8" of lift.

Note: This bracket will not fit a 1984, 1985 or 1986 XJ Cherokee without minor modification. If you "slot" the hole 3/8" lower, this bracket will fit. If you do not have the ability to slot the hole downward, do not purchase, as it will not bolt on your Jeep as is.

Note 2: If you have less than 1" or so of lift, you *MAY* get some rubbing between the new thicker track bar and the cover on your front differential. You can correct this couple of different ways:

1) Tap the cover inward with a hammer where it rubs, in order to clear. The steel is not thick, and it should be pretty easy. The internal moving parts are NOT in the area behind where the cover rubs (the only thing behind that portion of the cover is air), so you can safely tap it inward an 1/8" or 3/16" at the most

2) Replace your control arm bushings. If they are bad, sometimes the axle will rotate and slide a bit further forward than the factory had intended

3) Shorten your control arms by purchasing adjustable control arms or using the cam adjustments (varies by model)

4) Add 1" poly spacers to the front of your Jeep between the coil springs and the body, and you'll probably easily clear.
