Kartboy KB-003-Diff-S Subaru Rear Differential Cross-Member Bushings Soft Durometer

The Kartboy KB-003-Diff-S rear differential cross-member bushing set is engineered to replace worn or damaged factory rubber bushings in Subaru vehicles. These soft durometer polyurethane bushings provide a balanced upgrade between stock rubber compliance and firmer race-oriented options, delivering improved differential stability while maintaining acceptable NVH (noise, vibration, harshness) levels for daily driving.

Key Features:

• Soft durometer polyurethane construction for street-friendly comfort
• Reduces excessive differential movement under acceleration and cornering loads
• Improves power transfer efficiency and drivetrain response
• Direct replacement for factory rear differential cross-member bushings
• Maintains better NVH characteristics compared to race-spec bushings
• Manufactured from high-quality polyurethane for long service life

This bushing set is ideal for Subaru owners seeking improved differential control without the harshness associated with solid or race-compound bushings. The soft durometer formula makes these bushings well-suited for street performance applications, light track use, and spirited driving where maintaining comfort is a priority. Installation requires removal of the rear differential cross-member assembly.
