Powerflex Black Series Front Anti-Roll Bar Bush 26.5mm | BMW F8X M2 / M3 / M4
Improve front suspension response and anti-roll bar control with the Powerflex Black Series Front Anti-Roll Bar Bushes, designed for BMW M models equipped with a 26.5 mm front anti-roll bar.
Factory rubber anti-roll bar bushes can soften and deteriorate over time, allowing increased movement and deflection between the anti-roll bar and chassis. Replacing them with Powerflex polyurethane bushes provides a firmer mounting point, helping the anti-roll bar operate more consistently during cornering and rapid changes of direction.
Black Series Performance
Powerflex Black Series bushes are manufactured using the company’s Black 95 Shore A polyurethane compound, developed to provide maximum control of chassis geometry for track and motorsport-focused applications.
Reducing unwanted movement at the anti-roll bar mounting points can provide:
- More immediate anti-roll bar response
- Reduced bush deflection
- Improved front-end response
- More consistent handling under cornering loads
- Greater suspension feedback
- Increased durability compared with ageing factory rubber
For modified, performance-focused and track-driven F8X M cars, these bushes provide a straightforward upgrade without replacing the complete anti-roll bar.
26.5mm Anti-Roll Bar Fitment
PFF5-1203-26.5BLK is specifically designed for a 26.5 mm front anti-roll bar.
Powerflex also produces a 28 mm version for compatible vehicles, so the anti-roll bar diameter should be checked before ordering.
The bush cross-references BMW OE numbers:
31352283515
31352283516
31352283517
Why Choose Powerflex?
Factory suspension bushes are manufactured from rubber compounds designed to balance comfort, cost and performance. Over time, repeated loading, heat and environmental exposure can cause rubber bushes to soften and deteriorate, allowing greater movement within the suspension.
Powerflex polyurethane bushes are engineered to provide greater control and durability, helping maintain more consistent suspension geometry and response.
Key benefits include:
- Precision-engineered polyurethane construction
- Improved suspension control and response
- Reduced unwanted component movement
- Greater durability than conventional ageing rubber bushes
- Improved consistency under demanding driving conditions
- Powerflex Lifetime Warranty, subject to Powerflex warranty terms
Powerflex Black Series is the company’s track-focused range, developed for applications where maximum chassis control and precision are the priority.
