Maximize Drivetrain Efficiency with Whiteline Differential Bushings

Optimize the performance of your Scion FR-S, Subaru BRZ, Toyota 86, or Toyota GR86 with the Whiteline KDT923 Rear Differential Support Outrigger Bushing. This crucial component is designed to enhance the stability of the differential mount, ensuring that pinion angles remain consistent under load. By minimizing differential movement, you'll experience improved gear shifting, reduced initial torque loss, and ultimately, more efficient power transfer to the wheels.

Key Features and Benefits:

  • Stabilizes Differential Mount: Prevents excessive movement of the rear differential.
  • Maintains Pinion Angle: Ensures optimal driveshaft alignment for smooth power delivery.
  • Improved Gear Shifting: Results in crisper, more precise gear changes.
  • Reduced Torque Loss: Maximizes power transfer to the wheels for enhanced acceleration.
  • Durable Polyurethane: Built with high-quality materials for long-lasting performance and reliability.

Worn or soft factory differential bushings can lead to sloppy shifting and power loss, especially in performance applications. The Whiteline KDT923 bushing directly addresses these issues, providing a more solid and connected feel to the drivetrain. This upgrade is particularly beneficial for drivers who push their vehicles hard, whether on the track, autocross course, or during spirited street driving. Experience the difference that a properly supported differential can make in your car's overall performance and driving dynamics.

For top-tier drivetrain and suspension upgrades, trust Whiteline performance parts available at GGCRACING.
