The Powerflex Black Series Rear Diff Rear Mounting Bushes are a highly sought-after performance upgrade for road and track cars, offering unparalleled stiffness and control.
Building on the success of their Yellow and Purple Shore 70A/80A range, Powerflex has responded to the demand for an even more extreme compound by introducing their new Black Series range.
The Black Series bushes utilise the toughest Shore 95A compound, which is optimised for the most extreme track use. Compared to the Purple Series, these bushes are a further 25% stiffer, and up to around 80% stiffer than stock rubber bushes.
As a result, they provide uncompromising response and control in applications where additional vibration is not an issue.
The primary benefit of using these bushes lies in ensuring that every component in your suspension setup performs exactly as intended, without any compromise due to worn bushes. By utilising this grade of polyurethane bush, you can guarantee that the bushes are never the weak link in your suspension set-up.
Please note that these are the stiffest bushes Powerflex produces. If you require more compliant options, please consider their Yellow and Purple ranges.
For easy identification, each product is listed with a photo and a diagram showing where it fits on the car. The product page also lists the location of this bush on the diagram above.
These bushes can be used in multiple locations on the same diagram, as indicated by the product page. If you have any questions or concerns about compatibility or performance, please do not hesitate to contact us for more information.
