Kartboy 04-21 Subaru WRX STi Shifter Bushing Combo - 6-Speed. This direct-fit bushing kit is designed for 2004–2021 Subaru WRX and STi 6-speed models to sharpen shift engagement and reduce play in the shifter linkage.

The Kartboy combo replaces worn factory bushings to produce a firmer, more confident shift feel without changing shift gate geometry. It targets common sources of slop in the shifter assembly, giving drivers more precise gear selection and improved feedback during spirited driving or daily use. Installation is straightforward for anyone comfortable with basic hand tools, and the kit is designed to integrate with the factory shifter components for a clean fit and reliable operation.
