Who Are Powerflex?
Founded in the UK, Powerflex has become a global leader in performance suspension components. Their bushes are engineered to replace factory rubber items, which tend to degrade over time and allow excessive movement. By using polyurethane, a material known for its durability and resistance to wear. Powerflex bushes offer sharper handling, improved feedback, and longer service life.
They’re also ISO9001 certified and recipients of the Queen’s Award for Enterprise, which speaks volumes about their commitment to quality and innovation.
Product Range Overview
Powerflex bushes are available in several variants, each colour-coded to indicate their shore rating which is a measure of hardness, and should tie in with your intended use.

Each compound is carefully selected for its location-specific demands. Unlike brands that use a one-size-fits-all approach, Powerflex engineers tailor the durometer to suit the bush’s role, ensuring optimal performance without unnecessary harshness. Some products are only available in specific shore ratings to ensure you get the most out of your bushes.
Choosing the Right Bushes
Here’s a quick guide to help you decide which compound suits your needs:
-
Daily Driver/Fast Road Use
Go for Purple. It offers a noticeable improvement in handling and feedback without compromising ride comfort or NVH. -
Engine & Drivetrain Stability
Opt for Yellow. Its slightly softer compound absorbs vibrations better, making it ideal for mounts and subframes without introducing too many unwanted vibrations. -
Track/Motorsport Use
Choose Black. These are the stiffest bushes Powerflex offers, designed to maintain precise geometry under extreme loads. Be warned they are much stiffer than stock. Expect increased NVH (noise, vibration, harshness).
Maintenance & Longevity
Powerflex bushes come with PTFE-silicone grease, which is far superior to traditional lubricants. Thanks to clever grooves and knurls cast into the bush material, re-lubing is rarely needed. And with a lifetime warranty, you’re covered for the long haul.
Whether you're restoring a modern classic, refining your track weapon, or simply want a sharper drive, Powerflex bushes offer a proven upgrade. With colour-coded compounds and application-specific engineering, they take the guesswork out of suspension tuning, giving you confidence, control, and comfort where it matters most.
