Product details

PLEASE NOTE, A very limited number of 2004-2005 STI had a riveted joint from factory, if so you will need Subaru PN 35046FE010. Please verify before ordering. KB tested 2004 STIs in development. Neither had the riveted joint, so above note did not apply, and this joint will bolt right up.

This is the Kartboy 6-speed solid shift joint. 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.

The 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.

Designed 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.

A great upgrade when installing a short shifter, refreshing worn linkage components, or tightening up the overall feel of an aging STI 6-speed drivetrain.
