SPL Parts Solid Differential Mount Bushings for Nissan 370Z & Infiniti G37/Q40

Enhance the performance and reliability of your Nissan 370Z or Infiniti G37/Q40 with SPL Parts Solid Differential Mounting Bushings (SDBS). Designed for 2009 and newer models, these bushings replace the stock, silicone-filled differential bushing, which is prone to tearing under hard driving, with a solid billet aluminum solution.

Key Advantages of SPL SDBS:

  • Eliminate Bushing Failure: Prevents the common issue of stock bushing tearing and silicone leakage, ensuring long-term durability.
  • Reduce Wheel Hop: Significantly minimizes wheel hop during aggressive acceleration and launches, leading to improved traction.
  • Boost Power Transfer: Ensures a more direct and efficient transfer of power to the wheels, enhancing acceleration feel.
  • Protect Drivetrain Components: Helps prevent damage to the driveshaft and half-shafts by stabilizing the differential.
  • Precision Billet Construction: Manufactured from T6061 billet aluminum for a precise fit and superior strength.

The factory differential bushing is a known weak point in these vehicles, often failing under the stress of performance driving. SPL Parts SDBS provide a robust solution, keeping the differential firmly in place and preventing unwanted movement. This upgrade is essential for any owner looking to maximize launch grip, improve drivetrain response, and ensure the longevity of their vehicle's components. Experience a more connected and responsive drivetrain feel with this critical upgrade.

Secure your differential and optimize your performance with SPL Parts Solid Differential Mount Bushings. Available now at GGCRACING.
