Description

Restore the Suspension Performance of Your Freightliner

The Air Spring Freightliner W01-358-9780 is a direct-fit replacement for trucks that rely on rolling-lobe air springs for stable, smooth suspension performance. It installs in the factory location and restores correct ride height, stability, and load support.

If your truck leans, bounces excessively, or shows uneven suspension movement, this replacement air spring brings back the strong, level ride your Freightliner is designed for. A healthy air spring protects your frame, alignment, tires, and braking performance during daily operation.

Key Features

• Direct replacement for W01-358-9780

• Crosses with 1R12-303 and 9780

• Rolling-lobe air spring design

• Durable rubber construction

• OEM-style top and bottom plates

• Built for heavy-duty Freightliner applications

The shape, mounting points, and air connection match the original equipment, making installation simple and secure.

Why This Air Spring Matters

When an air spring begins to fail, you may notice:

• Extra bounce on rough roads

• Sagging or leaning rear suspension

• Vibration throughout the cab

• Uneven tire wear

• Harder braking and poor load control

A worn air spring can strain other suspension components. Replacing it restores proper damping and protects the truck during long-distance hauling and daily work.

Designed for Heavy-Duty Use

This rolling-lobe air spring is built for commercial service and handles:

• Long highway routes

• Heavy payloads

• Continuous road vibration

• Temperature and weather changes

• Repeated air-up cycles

The rubber bladder, bead plate, and crimp rings hold up to demanding use and maintain stable pressure.

Fitment Information

This air spring fits:

✅ Freightliner models using W01-358-9780
✅ Suspensions that require 1R12-303
✅ Applications cross-referencing 9780
✅ Rolling-lobe air spring systems

If you need help confirming fitment, we can check with your part number or VIN.

Installation Notes

Installation follows standard heavy-duty suspension service steps:

1. Release air pressure

2. Remove the old air spring

3. Install the new air bag into place

4. Bolt down top and bottom plates

5. Reconnect air lines
