Product Description

The Whiteline KDT911 Rear Differential Mount Bushing Kit delivers a complete solution for worn or deteriorating factory differential bushings on Nissan 350Z, 370Z, and Z, as well as Infiniti G35 and G37 models. Factory rubber differential bushings degrade over time, causing unwanted vibration, driveline noise, and excessive differential movement that reduces power transfer efficiency. This comprehensive kit includes all five bushings needed to completely replace both the front and rear differential mount bushings. Whiteline's proprietary synthetic elastomer material combines the strength and durability of solid bushings with the flexibility and NVH characteristics of rubber, providing a comfortable street driving experience without the harshness associated with typical polyurethane. The 70-80 durometer rating delivers a noticeable improvement in chassis response while maintaining daily driver comfort.

By eliminating differential housing movement, proper pinion angles are maintained throughout the drivetrain, resulting in improved gear shift feel, reduced torque loss, and more efficient power delivery to the wheels. The knurled inner surfaces of each bushing retain lubrication for long service life, while the included steel crush tubes ensure proper installation and consistent performance. Installation requires approximately 4 hours and is best performed by a suspension specialist. A rear wheel alignment is recommended after installation. Backed by Whiteline's 3-year/60,000-mile warranty.
