Description
Complete four-bush Black Series set for the front mountings of the rear differential. Powerflex PFR5-4025BLK replaces the four bushes in the original differential front mounting bracket on the listed BMW F87 M2 application. Aluminium sleeves incorporate additional support to help control differential movement.
What the set includes
The price covers four replacement bushes and their specified sleeve components. The original front bracket, identified by BMW reference 33172284774, is retained. This is not a new bracket, an insert-only product or a front-axle differential mount.
Black Series for a track-focused setup
This is the Black Series 95A specification. Choose it with the complete drivetrain setup in mind: firmer mounting can improve control of movement while transmitting additional noise and vibration. Compare the PFR5-4025 Road Series set when road refinement is a priority.
Rear bushes and the dual bracket are separate
PFR5-4025BLK renews the front mounting points of the rear differential only. The PFR5-4026BLK rear bush and PFR5-4030 dual rear bracket are separate purchases. G8x front mountings use PFR5-4024, not this set.
Fitment and installation
Check the original bracket and any differential modifications before ordering. Follow Powerflex instructions and inspect the other mountings rather than assuming one set will cure every rear-end noise. There is no blanket fitment guarantee for modified assemblies.
Read the F8x differential mounting guide, browse the Powerflex range or see the manufacturer specification.

Powerflex questions answered
Here' some of our most asked questions about Powerflex.
What does this Powerflex bush do?
Powerflex bushes are designed to replace the softer original rubber bushes fitted from factory. The aim is to reduce unwanted movement in the suspension, drivetrain or chassis, helping the car feel sharper, more stable and more responsive.
Depending on where the bush is fitted, it can improve steering feel, braking stability, gear changes, traction or overall handling.
Is this Powerflex bush suitable for road use?
Yes, many Powerflex bushes are suitable for road cars, especially if you want a more direct and controlled feel without going too extreme. They are a popular upgrade for fast road cars, daily drivers and weekend cars where the original rubber bushes are worn or too soft.
For more focused track or motorsport use, Powerflex Black Series options may be better suited where available.
Will Powerflex bushes make my car harsher?
You may notice a slightly firmer or more connected feel, especially when replacing larger suspension or drivetrain bushes. That said, most road-focused Powerflex bushes are designed to improve control without making the car uncomfortable.
More focused bushes, particularly motorsport-style options, can increase noise, vibration and harshness, so it’s worth choosing the right version for how you use the car.
What is the difference between Powerflex Road Series and Black Series?
Powerflex Road Series bushes are designed for road and fast road use. They usually offer a good balance between improved handling, durability and comfort.
Powerflex Black Series bushes are more focused and are generally aimed at track, competition or heavily modified cars. They can offer a more direct feel but may also increase noise and vibration compared with standard rubber or Road Series bushes.
Why should I replace my original bushes?
Factory rubber bushes wear over time. As they get older, they can allow extra movement, which may lead to vague steering, poor alignment control, knocking noises, uneven tyre wear or a less precise feel from the car.
Replacing worn bushes with Powerflex upgrades can help restore control and improve the way the car feels, especially on performance cars used for fast road or track driving.
Are Powerflex bushes worth it?
Yes, especially if your original bushes are worn or you want a sharper, more controlled setup. They are a popular upgrade because they can improve the feel of the car without needing to change major components.
They’re particularly worthwhile on performance cars where suspension feel, alignment stability and chassis response matter.
Do I need to replace bushes in pairs?
In most cases, yes. It’s best practice to replace bushes in matching pairs across the same axle or suspension position. This helps keep the car balanced and avoids one side feeling tighter or newer than the other.
If you’re unsure what should be replaced together, get in touch before ordering and we’ll help point you in the right direction.
Is fitting Powerflex bushes difficult?
Some Powerflex bushes are straightforward to fit, while others require more time, tools or workshop equipment. Many original bushes need to be pressed out before the new bushes can be fitted.
If you’re not confident with suspension work, we’d recommend having them fitted by a professional garage.
Do I need a wheel alignment after fitting Powerflex bushes?
For suspension-related bushes, yes, we’d strongly recommend a wheel alignment after fitting. Changing bushes can affect geometry, and a proper alignment helps make sure the car drives correctly, handles well and doesn’t wear tyres unevenly.
For drivetrain bushes or inserts, alignment may not be required, but it depends on the part being fitted.
Will these bushes fit my car?
Please check the product title, fitment notes and vehicle details before ordering. Some models have different bush sizes depending on year, chassis, suspension type or factory options.
If you’re not 100% sure, send us your vehicle details or registration before ordering and we’ll help confirm the correct Powerflex part for your car.
