The OEM 2013+ Track Bar has been upgraded from the previous 2003-2013 design, and is not "absolutely mandatory" to replace right away on a new truck, as previously suggested. If you're nearing 20,000 miles on the OEM Trackbar, it's a good idea to plan on getting our Trackbar as an upgrade.
Our Trackbar is designed to be VERY rigid. Often people will think that having a rigid track bar will give steering vibration and rattle. This is simply not true being that the Trackbar is technically a steering support. You want and steering supports to be as low deflection as possible.
Note on 2019+ trucks: While a rare occurrence, our trackbar can at times slightly rub the 2019+ Aluminum bolt-on frame side mount. This contact is VERY slight if at all, and causes no issue. If yours touches and you want to have zero contact at that location, a 30 second job with a flat file can provide all the clearance needed.
