PowerFlex Suspension Bushing Kits: Precision Polyurethane Engineering
PowerFlex has built its global reputation on one core philosophy: that suspension bushings should be engineered, not simply copied. PowerFlex is a truly engineered product — not just a copy of the stock part in a different material. Each bushing is redesigned to address common factory failure points, allowing the articulation required to maintain control of movement for increased performance while far outlasting the stock parts they replace.
Established in 1996, PowerFlex has specialised in engineering polyurethane suspension solutions for a wide range of vehicles. Their suspension bushing kits represent decades of motorsport-derived development, made available for everything from daily drivers to dedicated track cars.
Why Polyurethane Bushing Kits Beat OEM Rubber
Suspension bushings are among the most highly stressed components on any vehicle. They endure enormous strain with no maintenance or lubrication, and the rubber compound they are made from deteriorates with age — becoming softer and more pliable, offering less control over suspension geometry, which in turn causes accelerated tire wear, braking instability, and poor handling.
By correctly engineering the polyurethane compound, PowerFlex bushings can be made 25–30% stiffer than new rubber items, but with exactly the same noise-absorbing properties. PowerFlex polyurethane bushings are designed to decrease the amount of deflection in your car's suspension, which improves handling, driver feedback, and tire wear.
Product Lines: Road Series, Black Series & Engineering Line
PowerFlex suspension bushing kits are offered across distinct product lines, each tuned for a different driving purpose:
- Road Series: Designed for everyday driving, the Road Series provides a balance of performance and comfort with durability that outperforms traditional rubber bushings.
- Black Series: The PowerFlex Black Series line features high-durometer urethane and machined aluminum components in both standard and geometry-adjustable designs for the ultimate in handling performance.
- Engineering Line: Engineering Line products for select fitments include unique features like polyurethane monoballs and offset geometry to provide ultimate performance without the harshness of metallic race parts.
Bushings are produced in one of three durometers — Yellow (70A, approximately 25% stiffer than stock), Purple (80A, approximately 30% stiffer than stock), and Black (95A, approximately 80% stiffer than stock) — allowing drivers to dial in the exact balance of compliance and rigidity they need.
Engineering Quality & Built-In Longevity
The manufacturing process involves CNC machining and moulding to ensure every bushing meets exacting tolerances. Unlike generic polyurethane bushings, PowerFlex components are designed using CAD data and real-world testing to ensure they locate correctly, maintain proper suspension geometry, and deliver measurable performance improvements.
PowerFlex PTFE-Silicone grease is supplied with every bushing set, and is the only lubrication they recommend. Bushings will rarely need re-lubing due to the unique grooves and knurls cast into the material to hold the lubricant. A lifetime warranty is included on all bushings, underscoring the brand's confidence in long-term durability.
Many kits include CNC-machined aluminium outer shells for applications requiring maximum strength. This is particularly important when combined with other upgrades like coilover kits or lowering springs — there's little point fitting adjustable suspension if worn or soft bushings allow the geometry to shift under load.
Whether you're restoring worn handling to a road car or building a focused track-day machine, explore the full range of suspension bushing kits and the complete PowerFlex catalog to find the right kit for your application.
