Product Information

Full details

The Powerflex PFF5-701 Front Radius Arm to Chassis Bush is designed for automotive enthusiasts and drivers looking to restore or upgrade their vehicle's handling precision. By replacing deteriorating factory rubber with high-performance polyurethane, these bushes provide sharper steering feedback and improved suspension stability, making them an excellent choice for fast road and trackday applications. While they offer significantly better durability and performance than standard components, users should note that they require professional installation to ensure correct fitment and longevity.

Extended Product Information

FAQs

Are these bushes stiffer than standard rubber?

Yes, they are engineered to be 25-30% stiffer than factory-fresh rubber bushes.

Do I need special tools for installation?

Yes, a hydraulic press is often required to remove the old factory bushes and install the new Powerflex units.

Will these increase road noise in the cabin?

Powerflex designed these to maintain factory-level noise-absorbing properties while increasing performance, so any increase in cabin noise is typically negligible.

Can I install these myself?

If you have experience with suspension work and access to a hydraulic press, it is possible; otherwise, professional installation is advised.

Do I need to grease these bushes?

Yes, use the included grease during installation to ensure smooth articulation and to prevent potential squeaking.

Will these fit my vehicle?

The PFF5-701 is designed for specific chassis applications; always verify your vehicle's MPN compatibility before purchase.

Troubleshooting

Noise or squeaking coming from the suspension arm

Apply the provided specialized grease to the contact surfaces of the polyurethane bush and the metal insert.

Difficulty fitting the bush into the arm

Ensure the original rubber and its outer metal shell have been completely removed from the radius arm housing.

Steering feels off after installation

Check that the bushes were pressed in squarely and have a technician perform a full wheel alignment to correct geometry changes.

Pros and Cons

Pros

  • Significantly tighter and more responsive handling
  • Enhanced durability compared to standard rubber bushes
  • Corrosion-resistant stainless steel hardware
  • Optimizes suspension geometry for even tyre wear
  • Retains effective noise-absorption properties

Cons

  • Requires mechanical expertise for installation
  • May require professional workshop tools for bush extraction
  • Not intended for drivers seeking a 'softer' factory-like ride quality

Setup, Compatibility & Care

Installation of the PFF5-701 requires the removal of the existing radius arm from the chassis. Technicians must press out the old, worn rubber bushes completely before cleaning the arm's housing to ensure the Powerflex insert sits flush. It is highly recommended to use a small amount of the supplied grease during assembly to facilitate movement and prevent squeaking. Always verify alignment after installation, as changing from worn-out bushes to high-performance ones may slightly alter your suspension geometry. Periodic inspections during oil changes are recommended to ensure the bushes remain seated correctly and free from debris.
