The factory linkage in the STI 6-speed drivetrain was designed with comfort and vibration isolation in mind, but over time that rubber-isolated joint can introduce excess play and a disconnected feeling during shifts, especially during aggressive driving in a very legal manner or fast gear changes getting safely up to speed to merge on the highway.\u003c\/p\u003e\n\u003cp\u003eThe OEM setup uses a rubber-isolated joint that wears over time and absorbs shift input instead of transferring it directly to the transmission. The Kartboy solid shift joint replaces that factory assembly with a precision machined solid connection for a more direct and consistent gear change.\u003c\/p\u003e\n\u003cp\u003eDesigned for 2004–2021 Subaru STI 6-speed manual transmission applications, this kit was engineered from a clean-sheet design. The Kartboy solid shift joint features solid stainless machined center cross tubes, press-fit bronze bushings, and precision machined stainless crush tubes for a bind-free design while still allowing proper bolt torque - this is a component built to last.\u003c\/p\u003e\n\u003cp\u003eA great upgrade when installing a short shifter, refreshing worn linkage components, or tightening up the overall feel of an aging STI 6-speed drivetrain.\u003c\/p\u003e\n\u003cp\u003eInstall Guide\u003c\/p\u003e\n\u003cp\u003e\u003cspan itemprop=\"description\" id=\"product_description\"\u003e\u003cspan style=\"background-color: initial;\"\u003eFeatures :\u003c\/span\u003e\u003c\/span\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003e\u003cspan itemprop=\"description\" id=\"product_description\"\u003e304 stainless steel w\/ bronze insert\u003c\/span\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cspan itemprop=\"description\" id=\"product_description\"\u003e Improved shifts\u003c\/span\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cspan itemprop=\"description\" id=\"product_description\"\u003e Eliminates shifter slop\u003c\/span\u003e\u003c\/li\u003e\n\u003cli\u003e\n\u003cspan itemprop=\"description\" id=\"product_description\"\u003e Direct replacement of OEM linkage u-joint\u003c\/span\u003e\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cspan itemprop=\"description\" id=\"product_description\"\u003e Install hardware included\u003c\/span\u003e\u003cbr\u003e\n\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003eFitment note :A very limited number of 2004-2005 STI had a riveted joint from factory, if so you will need this \u003ca href=\"https:\/\/www.fastwrx.com\/products\/subaru-shift-linkage-6mt-joint-2004-2021-sti?variant=42514107990104\"\u003eSubaru part\u003c\/a\u003e  \u003cstrong\u003ePlease verify before ordering.\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eFits all 2006-2021 six-speed (6MT) Subaru WRX STI.
