This 3-piece kit completely replaces the OEM plastic bushings for the 16-19 Manual ATS-V shifter. If you have side-to-side or fore-and-aft play while in gear, your bushings are most likely bad.
The bushing at the base of the OEM shifter is made out of a thermoplastic that deforms under heavy shifting. We replaced this with a bearing bronze bushing that will not oval out prematurely.
The OEM bushings at the transmission end of the shifter linkage are also made out of a thermoplastic that creates more slop once they wear out. We replaced these bushings with machined Delrin, giving the best compromise between wear and noise reduction.
