Shift Lever Isolator is it needed at all

[donb]

Looking at various shifter options for my 2015.

Here is the Mopar Shift Lever Isolator that the stock shift knob screws into: https://www.dodgeparts.com/oem-parts/mopar-shift-lever-isolator-4709410

Does anyone know how important that is? Has anyone removed it, did it cause shifting issues, or crazy vibration in the shifter?

Some shifter kits that lower the shifter have you take it completely off and not replace it, example: http://www.specialtyperformanceteam.com/shop/pc/Viper-Shifter-Knob-Lowering-Kits-1-and-2-p160.htm

Thanks in advance.

A lot of the G2 aftermarket shafts did not have them, I never noticed any diff from oem.
