I just purchased the RE1600 through Amazon for $130.00 delivered.
(it just felt like the thing to do at the time)
When I did my 3" lift a couple years ago, I removed the original track bar, cut it, added a welded external sleeve to extend it to the needed length and have beat the crap out of it without issue.
Now the RE bar arrives and it is tubing verses the oem solid bar, I have now drilled out the taper frame side mount so there is no going back.
After comparing the rotational angle differences between the heim joint and the tie rod end style, there really does not seem to be any difference.
At 3" I don't feel double shear is really necessary but if this single shear heim turns into an issue then I will re-think that and get a stock, unmolested factory bracket and go back to my original Extendo- Bar.
Bottom line is I probably should had left well enough alone, I will see !
But hey, it's only money right ? Plus now, I have a RE sticker for my tool box.
