Optimize your Subaru's rear-wheel power delivery with the Whiteline Rear Differential Mounts Positive Power Kit (WHLKDT906). This essential upgrade focuses on the rear differential, ensuring that pinion angles are correctly maintained under load. This precision is vital for reducing initial torque loss, which means more of your engine's power is effectively transferred to the road.

Key Features:

  • Maintains Optimal Pinion Angles: Critical for consistent performance and drivetrain longevity.
  • Reduces Initial Torque Loss: Maximizes power delivery to the wheels.
  • Enhances Gear Shift Feel: Contributes to a more precise and satisfying shifting experience.
  • High-Quality Materials: Built with Whiteline's commitment to durability and performance.

Designed for a wide array of Subaru models including the Forester, Impreza, WRX, and STi, this kit addresses common drivetrain flex issues. By reinforcing the differential mounts, you gain a more solid connection between the engine and the wheels, leading to improved traction and handling. Whether you're pushing your vehicle on the track or enjoying spirited street driving, the Whiteline Positive Power Kit offers a tangible improvement in performance. Invest in a more responsive and powerful Subaru with this premium differential bushing solution from GGCRACING.
