Kartboy KB-003-Rear Auto Trans Mount Bushing

The Kartboy KB-003-Rear is a performance rear automatic transmission mount bushing designed to reduce drivetrain movement and improve power transfer efficiency. This bushing replaces the soft factory rubber mount with a firmer, more durable polyurethane construction that minimizes transmission movement under acceleration and shifting.

Key Features:

• High-durometer polyurethane construction for long-lasting performance
• Reduces transmission movement and wheel hop during hard acceleration
• Improves shifting feel and drivetrain response
• Direct replacement for worn or soft factory bushings
• Precision-engineered for proper fitment and alignment

This rear transmission bushing is ideal for enthusiasts looking to tighten up their drivetrain feel and reduce the slop associated with worn factory mounts. While it may transmit slightly more vibration than stock rubber mounts, the improved throttle response and reduced drivetrain movement make it a popular upgrade for performance-oriented drivers.
