Frequently Asked Questions About International WorkStar Steer Axle Springs & Hangers

Will these springs and hangers fit my specific WorkStar model year?

These steer axle springs and hangers are designed to fit International WorkStar models from 2008-2018. However, compatibility can vary based on your truck's specific configuration, including GVWR rating and whether you have a setback or set-forward axle. We recommend checking your VIN or contacting us with your truck's specifications to ensure proper fitment before ordering.

What weight capacity should I choose for my application?

The correct spring capacity depends on your front axle weight rating (FAWR). Most WorkStar models use either 12,000 lb or 14,000 lb rated springs for the steer axle. You can find your required capacity on the driver's door jamb sticker or in your owner's manual. Using incorrect capacity springs can cause poor ride quality, premature wear, or safety issues.

Can I install these springs and hangers myself, or do I need special tools?

While installation is possible for experienced mechanics, it requires heavy-duty spring compressors, proper jack stands rated for commercial trucks, and torque specifications. The job typically takes 4-6 hours per side. Many customers report that improper installation can lead to alignment issues or premature bushing failure. We recommend professional installation unless you have commercial truck experience and the necessary equipment.

How long do these springs typically last, and what are signs they need replacement?

Quality steer axle springs generally last 300,000-500,000 miles under normal conditions. Common signs of wear include: sagging ride height (more than 1 inch difference side-to-side), cracked or broken leaves, excessive rust between leaves, worn eye bushings causing clunking sounds, or uneven tire wear on the front axle. Regular inspection during oil changes can help catch issues early.

What's the difference between OEM and aftermarket options you carry?

OEM springs are manufactured to International's exact specifications and typically carry a 3-year warranty. Aftermarket options from brands like Dayton and Hendrickson often use upgraded steel alloys and improved bushing materials, potentially offering longer service life at a lower price point. Both meet or exceed DOT safety standards. The main differences are price (aftermarket is usually 20-30% less) and availability (aftermarket typically ships faster).
