As your E30 ages, the rear differential bushing can crack, dry rot, and split. It's time for an upgrade. The ECS Tuning Heavy Duty Differential Bushing is crafted with performance in mind. Instead of using polyurethane, which is known for increasing NVH, the enthusiasts at ECS chose HD 70D rubber. This material offers a close-to-factory feel without the excess deflection of softer bushings, ensuring a pleasurable driving experience free from differential whine and excess movement.

Features & Benefits:

Eliminates Weak OEM Mount: The aging E30 chassis deserves an upgrade. Replace your old, cracked, and worn factory bushing with this HD alternative for improved performance. Perfect for Street or Track: Constructed from HD rubber instead of polyurethane or Delrin, this bushing provides comfort for daily driving while remaining effective in performance applications. Added Responsiveness: The 70D HD rubber compound is stiffer than the stock material, reducing drivetrain movement and effectively locking down your rear differential. Easy Installation: Precision-manufactured to the exact specifications of your OEM differential bushing, the ECS heavy-duty replacement installs just like the factory component. Whether you are replacing an aging factory bushing, removing excess driveline movement, or balancing performance and comfort, ECS Tuning has you covered with their Heavy Duty Rear Differential Bushing.
