Product Description

The Torque Solution TS-SU-708 Complete Shifter Bushing Combo Kit is designed for the Subaru WRX STI from 2006 through 2021, replacing the factory rubber shifter bushings with precision engineered Delrin and polyurethane components. Soft or worn OEM bushings can introduce sloppy shift feel, excessive movement, and inconsistent gear engagement - especially under performance driving conditions. By upgrading to this combo kit, you'll achieve crisper, more direct gear changes, reduced play in the shifter mechanism, and improved overall transmission feel.

Installation is direct-fit and typically takes under 30 minutes. The kit addresses both the linkage bushings and the rear mount bushing, giving a comprehensive improvement to the shifter system. It's ideal for street enthusiasts, weekend track drivers, or anyone seeking a firmer, more responsive shift feel in their Subaru STI. After installation, a proper shift linkage inspection and ensuring all bolts are torqued to spec is recommended. Because the drivetrain is AWD and the body/gearbox remains standard, no drivetrain modifications are required.

Fitment is confirmed through model year 2021; any 2022 or newer models are unconfirmed at the time of this listing. Always verify your vehicle's transmission type (6MT), year, and that your chassis is a WRX STI variant before purchase.
