The Powerflex PFR5-426 Rear Differential Diff Bush Pair is designed for vehicle owners seeking to enhance their suspension's performance and durability. Its key benefit is reducing imprecise handling and improving tyre wear by replacing worn rubber bushes with robust polyurethane. A potential caveat is that its firmer nature may introduce more road noise compared to standard bushes. This product offers a durable upgrade for a more responsive and stable driving experience.

Polyurethane bushes offer superior durability and performance compared to standard rubber bushes, providing a more direct and responsive feel while resisting wear and deformation.
While polyurethane is firmer than rubber, the PFR5-426 are designed to enhance performance without making the ride excessively harsh. Some increase in road noise or vibration is possible.
Powerflex bushes are known for their longevity and can last significantly longer than original rubber components, often outlasting the vehicle's lifespan under normal conditions.
Basic suspension tools are usually sufficient. However, a press is highly recommended for easier and safer installation of the bushes into their housings.
Shore A hardness is a measure of the material's firmness. A rating of 80 indicates a relatively firm but still slightly flexible polyurethane, balancing performance with some compliance.
It is generally recommended to use components from the same manufacturer for optimal compatibility and performance. Mixing brands may lead to unexpected results.
Powerflex typically offers a lifetime warranty on their products against manufacturing defects, subject to terms and conditions.
This can be normal as polyurethane is stiffer than rubber. Ensure bushes are correctly seated and not binding. If excessive, consult a professional mechanic to confirm correct installation.
Double-check that all mounting bolts are torqued to the manufacturer's specifications. Ensure the correct bushes for your vehicle model were installed.
Ensure the mounting points are clean and free of debris. A light application of silicone grease can aid insertion. If significant force is required, consider using a press or seeking professional assistance.
Setup: Installation involves removing the old rubber differential bushes and pressing in the new Powerflex polyurethane bushes. While no special tools are strictly required beyond standard suspension service tools, a hydraulic press can make the installation process smoother. Ensure the mounting surfaces are clean before fitting.
Compatibility: These bushes are designed for specific vehicle models. Always verify the Powerflex PFR5-426 part number against your vehicle's make, model, and year, and check the fitting position (Rear Differential) to ensure correct application.
Care: Powerflex polyurethane is a low-maintenance material. Cleaning can be done with mild soap and water. Avoid using petroleum-based solvents or degreasers, as these can degrade the polyurethane over time. Regular inspection for any signs of damage or excessive wear is recommended, though failure is rare with proper installation and use.
