Just like other wear and tear items, your factory rear shifter bushing will become soft overtime, creating a loose shifter feel and increased movement under all acceleration circumstances. The Kartboy unit eliminates this problem by tightening up any loose ends with their much stiffer design.
These are 100% guaranteed, and hand made in the USA.
Please note that this bushing may raise the shifter height when used on 1998-2005 Forester, 2000-2004 Legacy, 2003-2006 Baja, and 1998-1999 Legacy Outback models.
