Adding your products to cart

Our International 9300/9370 Steer Axle Springs-Hang selection offers a variety of parts to support and maintain your truck's front axle suspension. These components, from parabolic leaf springs to alignment shims and installation hardware, ensure proper wheel alignment and ride quality. Whether performing routine maintenance or customization, you'll find durable, reliable solutions for your International trucks.

Frequently Asked Questions About International 9300/9370 Steer Axle Springs-Hangers

What is included in this category?

This category covers front steer axle leaf springs and the spring hangers (brackets) used to mount them to the frame rail on International 9300 and 9370 models. Steer axle springs support the front axle and manage ride height and load distribution, while hangers anchor the spring assembly securely to the chassis.

How do I know if my springs or hangers need to be replaced?

Common signs include visible cracks or broken leaves, sagging front ride height, uneven tire wear, a rough or bouncy ride, or clunking noises over bumps. Hangers should be inspected for cracked welds, elongated bolt holes, or rust-through, since a failing hanger can allow the spring to shift out of position.

Will these springs and hangers fit my specific 9300 or 9370 model year?

Fitment can vary by model year, GVWR rating, and axle configuration, so its important to check part numbers and weight capacity against your trucks specifications before ordering. If you are unsure, have your VIN or axle tag information on hand and reach out to our parts team to confirm the correct fit.

Are these parts made from the same material and rated the same as OEM springs?

Steer axle springs in this category are typically constructed from heavy-duty steel to handle front axle loads, similar to original equipment. Load capacity and leaf configuration can differ between suppliers, so review the listed specifications to make sure the springs match your trucks weight rating and application.

Can I install steer axle springs and hangers myself, or should a professional handle it?

Replacing steer axle springs and hangers involves supporting axle weight, removing U-bolts or spring pins, and properly torquing hardware to spec, which can affect steering and alignment if done incorrectly. Unless you have experience with heavy-duty front suspension work, we recommend having the job done by a qualified truck technician to ensure proper fit, torque, and safety.
