Specifications

 

Part Details:

The factory rear shifter bushing on these Subaru platforms softens over time, allowing extra play at the base of the shifter and a looser, less precise shift feel. This Kartboy rear shifter bushing replaces it with a 95A durometer polyurethane piece, hand made in the USA, that tightens the shifter mounting base and noticeably sharpens shift feel.

A simple, inexpensive upgrade on its own, and a common pairing with Kartboy’s front shifter bushing or short shifter for a complete shifter feel overhaul.

Key Features

  • Fits 2002 to 2014 Subaru WRX and 2004 to 2021 Subaru STI
  • 95A durometer polyurethane construction, hand made in the USA
  • Tightens the shifter mounting base and reduces shift slop
  • Includes the bushing and two mounting bolts
  • Installs in approximately 30 minutes

Frequently Asked Questions

What does the rear shifter bushing actually fix?

It stabilizes the base of the shifter, which softens and develops play over time on the factory rubber bushing, resulting in a looser, less precise shift feel.

Do I need the front bushing too?

This is the rear bushing only. Many owners pair it with Kartboy’s front shifter bushing for the most complete improvement in shift feel.

Is installation difficult?

Most owners complete it in about 30 minutes with basic hand tools, though some report the rear bushing specifically can be a bit more involved to access than the front.
