Whiteline KDT990 Rear Differential Mount Bushing Kit for BMW F10 5-Series

The Whiteline KDT990 is a high-performance polyurethane rear differential mount bushing kit designed for BMW F10 5-Series models. This upgrade replaces the factory rubber differential mount bushings with precision-engineered synthetic elastomer bushings that dramatically reduce differential movement under acceleration and load.

Key Features:

• Premium polyurethane construction resists crushing and wear far better than original rubber mounts
• Reduces wheel hop and drivetrain slop for improved power transfer and traction
• Enhances throttle response and acceleration consistency, especially in high-torque applications
• Maintains NVH (noise, vibration, harshness) levels suitable for street driving
• Direct replacement design installs with factory hardware
• Whiteline's synthetic elastomer formulation provides superior longevity compared to OEM rubber

This differential mount bushing kit is an essential upgrade for enthusiasts looking to sharpen drivetrain response and reduce compliance in the rear subframe mounting system. Compatible with both rear-wheel drive and xDrive all-wheel drive variants.
