Whiteline is the Australian leader in handling-focused suspension hardware — anti-sway bars, control arm bushings, alignment correction kits, and limited-slip differentials. Engineered for Subaru WRX/STI, Mitsubishi EVO, and modern performance platforms.
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.
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.
