Hyper-Flex® Polyurethane Construction

Energy Suspension’s proprietary Hyper-Flex® polyurethane is engineered to outperform conventional rubber bushings.

Benefits include:

• Superior wear resistance
• Reduced suspension deflection
• High load capacity
• Excellent dimensional stability
• Long service life

Unlike rubber, polyurethane maintains its shape without permanently compressing over time.

Restore Leaf Spring Performance

Worn leaf spring bushings can contribute to:

• Rear suspension clunks
• Excessive axle movement
• Poor handling
• Wheel hop
• Uneven tire wear
• Reduced towing stability

Replacing old bushings restores proper spring movement and improves overall suspension performance.

Built for Harsh Conditions

Hyper-Flex polyurethane is highly resistant to the elements that commonly damage factory rubber.

It resists:

• Motor oil
• Grease
• Road salt
• Ozone
• Moisture
• Dirt and debris
• Common underbody chemicals

This makes it ideal for vehicles that see frequent towing, hauling, or off-road use.

Improved Handling & Stability

Installing polyurethane leaf spring bushings can help:

• Improve rear axle control
• Reduce unwanted spring movement
• Increase handling precision
• Improve towing stability
• Reduce suspension flex

These benefits are especially noticeable on higher-mileage trucks and SUVs with worn factory bushings.

Installation

Typical installation includes:

1. Safely support the vehicle and rear axle.
2. Remove the leaf spring mounting hardware.
3. Press or remove the old rubber bushings.
4. Install the new polyurethane bushings and sleeves (if applicable).
5. Reassemble the suspension and torque all hardware to factory specifications.

Depending on the application, a hydraulic press or specialized bushing removal tools may be required.

Benefits After Installation

Replacing worn leaf spring bushings can provide:

• Improved suspension stability
• Reduced axle movement
• Longer bushing life
• Better handling
• Increased resistance to harsh environments
