KOR-1199-KIT Super-hard Durometer Track Bars Bushings
Hard-KOR Super-hard Rockwell Durometer (75d) bushings for Track Bars
KOR-1199 Bushing Upgrade Kit
Due to the problem our customers were having with Death Wobble, we did some experimentation with stiffer aftermarket track bar bushings, and found we were able to cure the Death Wobble on our test rig after they were installed on. Armed with this knowledge, Kevin found a polyurethane molding company who was willing to build a mold and pour us the hardest track bar bushings that exist...at least 25% stiffer than the STIFFEST ones that we had the early success with...which will work in track bars built by Jeep/Mopar/Dodge, as well as MANY different aftermarket track bar manufacturers, so long as that bar has the "standard aftermarket track bar end-loop size", which measures 1-1/2" Inside Diameter and has a width of 1-3/16". Measure your bar to see if it will work...it fits many different aftermarket bars, as well as our Track Bar Conversion, and MAY OR MAY NOT fit imported OE "equivalent" track bars from AutoZone and so on. This is perhaps the least expensive way to tighten up your steering system, removing slop, and perhaps even cure Death Wobble at the same time!
The result has been superior. We have been able to cure our customer's Death Wobble in most all cases with our SuperDurometer bushings, a new Hard-KOR steering stabilizer, and a proper alignment.
WJ Grand Cherokee Notes: This kit is direct-swap replacement for bushings on the JKS-127 bar for the WJ Grand Cherokee. Use the sleeves the JKS track bar came with, and our KOR-1199 bushing kit, unless you have damaged hardware and need to fix 'wallowed' bolt holes. If so, see below to see if our KOR-1189-S (with sleeves) would work better for you.
MAKE SURE TO PURCHASE THE KOR-1189-S KIT WITH SLEEVES IF YOU WANT TO UPGRADE TO OUR BUSHINGS USING A TRACK BAR THAT PREVIOUSLY DIDN'T USE A 7/8" OD SLEEVE. THIS 1199-KIT COMES WITHOUT SLEEVES AND BOLTS.
**Conventional petroleum-based lubricant or grease must NOT be used to lube or install poly bushings. These products will break down the polyurethane prematurely causing bushing failure. Please use only mineral-based lubricant, such as our KOR-1109 lube or a similar product from a poly bushing manufacturer.**
**A note about retrofitting your ORGS, JKS, or other aftermarket track bar with our Super-Durometer bushings mentioned above: Many factory and aftermarket track bars come with rubber press-fit cartridge-style bushings installed, rather than the easily-replaceable method of using two poly bushing halves, inserted from each side of the end loop, and then sliding the included thick steel sleeve inside the bushings. If you have the rubber-cartridge style bushings, then you cannot use the Super-Durometer 75D bushings without first removing that rubber cartridge bushing completely from your bar.
2007+ Wranglers: **These bushings will fit the UPPER loop of your factory track bar, but will not fit the LOWER loop.
2008+ Dodge Trucks: **These bushings are NOT compatible with the factory track bar on 2008+ Dodge trucks, due to a change in the bushing size.**
