Description
Powerflex Rear Differential Front Mount Inserts for BMW 2 Series (F22) / BMW 3 Series (F30) / BMW 4 Series (F32).
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 2 Series (F22) / BMW 3 Series (F30) / BMW 4 Series (F32).
Technical details
- Construction: reinforcement insert for the compatible original mounting arrangement. It is not a complete replacement mount; the retained mount must be suitable for reuse.
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.
