Due to the problem we 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.
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.
**This kit only includes two bushing halves, which will only service one end of a track bar. This is suitable for the track bars that have rubber or poly bushings on one end, and a johnny joint or flex joint on the other. This kit also includes the necessary hardware for installing our bushings in a track bar that has an OEM style cartridge rubber bushing. The hardware kit includes hardware for both ends of the track bar, which will come in handy if you decide to upgrade to a double shear track bar setup.
All products in this Death Wobble Cure package are proudly American-Made!
**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 Synthetic Silicone/Teflon lubricant, such as our KOR-1109 lube (included with this kit) or a similar product from a poly bushing manufacturer.**
**Please note: These bushings are NOT compatible with the factory track bar on 2008+ Dodge trucks, due to a change in the bushing size.**
