Description
Powerflex Rear Differential Front Mount Bushings for BMW F3X 3 & 4 Series / BMW 3 Series (E9X) / BMW 1 Series (E82) / BMW E84 X1.
Function and design
Differential mounts locate the final-drive assembly as it reacts to driveline torque. Movement at a worn mounting point can affect how the assembly responds to changes in load.
What to consider
Mounting position matters: front and rear differential bushings can have different dimensions and load paths. A firmer bushing can transmit more drivetrain noise, so consider isolation as well as movement control.
Application
- BMW F3X 3 & 4 Series
- BMW 3 Series (E9X)
- BMW 1 Series (E82)
- BMW E84 X1
Technical details
- Construction: replacement mounting bushing. Confirm the original housing or bracket arrangement; a bushing listing does not imply that a complete mount or bracket is included.
Choose your series
- Street: the road-oriented series; compound selection depends on the individual application.
- Black Series: the firmer series generally intended to prioritize movement control. Product-specific fitment and intended-use restrictions still apply.

Installation considerations
Match the exact differential mounting position and drivetrain application. Inspect the brackets and adjacent mounts, support the assembly during removal and follow the part-specific installation sequence.
