one pic says it all, from IRO site. Stock vs. IRO, which tie rod would you rather be runnin??

 

whats the difference between regular and double shear track bar?

 

Stock uses a regular ball joint end to mount to the "frame" end, allowing very little movement/drop, and the double shear changes the ball joint mount to polyurethane bushing end which allows as much articulation as your suspension will handle.

The pic shows a ball joint end




Below shows the double shear end.



See the difference?

 

not only does it allow for more flex but the bushings are said to not wear out as fast as the Tie rod ends do.

I just ordered a double sear one from IRO yesterday

 

Gpxj is on the money, same tres with a better bar.

Don't believe it? Go check part numbers lol.
