Subaru WRX Bushing Kit - Rear - Kartboy - Soft - `02-`07. This Kartboy rear differential bushing kit is a soft urethane replacement designed for 2002-2007 Subaru WRX and 2004-2007 WRX STI models. It restores factory fit while offering improved feel over aging rubber components.

The soft durometer formulation reduces drivetrain harshness and helps quiet clunks and vibrations that can develop as original bushings age. These bushings are made to be a direct fit for the rear differential mounts, so installation uses existing hardware and follows factory locations. Enthusiasts will appreciate the balance between comfort and control — firmer than worn rubber but tuned to avoid transmitting excessive noise into the cabin. This kit works well for daily-driven cars and lightly modified street builds.

• Soft urethane compound for reduced NVH compared to worn rubber
• Durable material designed for longer service life than OE rubber
• Compatible with 2002-2007 WRX and 2004-2007 WRX STI rear differential
