Whiteline 6-Speed Gearbox Selector Bushing Kit for Subaru WRX STI

Elevate your Subaru WRX STI's performance with the Whiteline Gearbox Selector Bushing Kit (KDT958), engineered specifically for the 6-speed manual transmission. This kit targets the inherent slop and vagueness found in OEM shifter bushings, replacing them with a high-performance, low-compliance solution. The result is a dramatically improved shifter feel, characterized by crisp, precise, and confident gear changes.

Key Advantages:

  • Eliminates Shifter Play: Reduces unwanted movement in the shifter linkage for a more direct connection.
  • Crisp & Precise Shifts: Experience a noticeable improvement in the clarity and accuracy of each gear engagement.
  • Enhanced Throttle Response: Minimizes drivetrain lash during on/off throttle transitions, contributing to a more responsive feel.
  • Reduced Missed Shifts: The improved precision helps prevent accidental engagement of the wrong gear, especially under demanding conditions.
  • Durable Design: Constructed with high-quality materials to ensure long-lasting performance and reliability.

This selector bushing kit is a must-have for WRX STI owners who push their vehicles to the limit, whether on the track, rally stage, or spirited street driving. By firming up the shifter linkage, drivers gain greater confidence in their gear selections, leading to faster lap times and a more engaging driving experience. The kit also incorporates a radius-edged flanged bushing head to prevent binding, ensuring a smooth and consistent shift action.

Vehicle Fitment:

  • Subaru Impreza WRX STI: 2004, 2005, 2006, 2007, 2008, 2009, 2010, 2011, 2012, 2013, 2014 (GD/GV/VA chassis)
  • Includes various submodels such as Base, Limited, Special Edition, and Type RA.
  • Also fits select Subaru Legacy models from 2005-2009 (check specific fitment).

Maximize your shifting potential with the Whiteline 6-Speed Gearbox Selector Bushing Kit, available now at GGCRACING.
