Kartboy KB-20-STI 2004-2021 Subaru WRX STI 6-Speed Short Shifter Kit

The Kartboy KB-20-STI Short Shifter Kit is designed for 2004-2021 Subaru WRX STI models equipped with a 6-speed manual transmission. It shortens shift throw compared with the factory shifter, helping create quicker, more deliberate gear changes while maintaining a direct mechanical connection between the driver and transmission.

Engineered for performance-oriented street and competition applications, the Kartboy short shifter kit uses durable construction to withstand repeated shifting and demanding driving conditions. Its application-specific design supports straightforward installation on compatible Subaru vehicles and works with the factory 6-speed shifter system. The result is a more engaged shifting experience without requiring a complete transmission replacement or extensive drivetrain modifications.

The Kartboy KB-20-STI is an appropriate upgrade for drivers seeking improved shift speed, reduced shifter movement, and a more precise feel from their Subaru WRX STI. Verify the vehicle model year and transmission configuration before ordering to ensure proper fitment. Professional installation is recommended, and related shifter components should be inspected during installation for wear or damage.
