Focused on quality, compatibility, and value, these drive axle springs and hangers are essential for keeping your ProStar on the road and performing at its best.

Frequently Asked Questions About International ProStar Drive Axle Springs & Hangers

What do drive axle springs and hangers do on my International ProStar?

The drive axle springs (leaf springs) support the weight of the truck and trailer over the rear drive axles, absorbing road shock and helping maintain ride height and axle alignment. The hangers are the mounting brackets that attach the spring assembly to the frame, keeping everything properly positioned under load. When either component wears out or breaks, you may notice uneven ride height, poor handling, or unusual noises over bumps.

How do I know if I need new springs versus new hangers?

A cracked or sagging leaf spring, a shifted axle, or a noticeable lean to one side usually points to spring failure. Hanger problems often show up as excessive movement in the suspension, elongated bolt holes, visible cracks in the bracket casting, or metal fatigue where the hanger bolts to the frame. If you are unsure after a visual inspection, having a qualified technician check the suspension under load is the best way to confirm which part needs replacing.

Will these parts fit any International ProStar, or do I need to match a specific model year or axle configuration?

Suspension components can vary based on axle capacity, spring type, and model year, so it is important to confirm the specs of your specific ProStar before ordering. Check your truck's axle rating and existing spring/hanger part numbers when possible, and reach out to our team if you need help confirming fitment for your configuration.

Are these springs and hangers OEM parts, aftermarket, or reconditioned take-offs?

Our inventory includes a mix of new aftermarket, OEM, and quality used take-off parts pulled from trucks in our salvage yard. Each listing specifies the condition and source of the part, so you can choose based on your budget and preference. If a listing does not clearly state the condition, feel free to contact us for clarification before purchasing.

What should I check or do during installation to avoid problems down the road?

Always inspect mounting bolts, bushings, and U-bolts for wear when installing new springs or hangers, since worn hardware nearby can undermine a good replacement part. Torque all fasteners to the manufacturer's specifications, and after installation, have the alignment and ride height checked to make sure the axle is properly seated. If you are not experienced with heavy-duty suspension work, having a qualified diesel technician handle the installation is recommended.
