E8X/E9X Solid Differential Bushing Kit
BMW E8X/E9X Billet Aluminum Differential Bushings
Eliminate differential movement and improve drivetrain response with our solid billet aluminum differential bushings for BMW E8X and E9X chassis.
CNC-machined from high-strength billet aluminum and finished in gold anodizing, these bushings replace the soft factory rubber mounts with a rigid, durable solution designed for high-performance street, drag, drift, and road-race applications.
Precision Knurled Press-Fit Design
The outer surface of each bushing is knurled to create a secure fit within the subframe. This added surface engagement helps prevent the bushing from rotating, shifting, or walking out.
Why Upgrade to Solid Differential Bushings?
Factory rubber bushings allow the differential to move under acceleration, braking, and shifting. As the bushings wear, this movement can contribute to drivetrain slop, wheel hop, and inconsistent power delivery.
Solid aluminum bushings provide:
- More direct power transfer
- Reduced drivetrain movement and slop
- Improved traction during hard launches
- Reduced wheel hop
- Sharper throttle and shifting response
- Greater durability
Available Versions
Non-M: For all non-M BMW E8X and E9X rear subframes, regardless of whether the vehicle uses a non-M or M3 differential.
M3 / 1M: For BMW E82 1M and E9X M3 rear subframes.
Fitment
- BMW E81, E82, E87 and E88
- BMW E90, E91, E92 and E93
- BMW E82 1M
- BMW E90, E92 and E93 M3
Solid differential bushings will transmit more drivetrain noise and vibration into the chassis than factory rubber mounts. This is expected and should be considered for vehicles focused primarily on comfort. We know you know this, and we know you are about to wear some tires out!
