Frequently Asked Questions About International 9300/9370 Leaf Springs, Hangers & Accessories
What years and models do these leaf springs fit?
Our leaf springs and hangers are designed to fit International 9300 models from 1987-2003 and International 9370 models from 1997-2003. However, compatibility can vary based on your truck's specific configuration, including wheelbase, suspension type, and whether you have a single or tandem axle setup. We recommend checking your VIN or calling our support team at 1-888-875-7787 with your truck's details to ensure proper fitment.
Are these OEM replacement parts or aftermarket?
We carry both OEM-specification and heavy-duty aftermarket options. Our aftermarket leaf springs are manufactured to meet or exceed OEM standards, using high-grade spring steel with proper heat treatment. Many drivers prefer our heavy-duty aftermarket options as they often provide better longevity under heavy loads compared to factory springs. Each product listing specifies whether it's OEM or aftermarket.
How difficult is the installation process?
Installing leaf springs typically requires 3-5 hours per side for experienced mechanics. You'll need proper jack stands, spring compressors, and standard hand tools. The most challenging aspects are safely supporting the truck's weight and aligning the spring eyes with the hangers. Many customers report that having a helper makes the job significantly easier. If you're not comfortable with heavy suspension work, we recommend professional installation, which usually runs $400-800 depending on your location.
What's the weight capacity difference between standard and heavy-duty springs?
Standard replacement springs typically match your truck's original GVWR rating, while our heavy-duty options can increase capacity by 10-20%. For example, if your 9300 came with 12,000 lb front springs, our heavy-duty replacements might be rated for 14,000-15,000 lbs. Keep in mind that increasing spring capacity affects ride quality - heavier springs provide less cushioning when running empty or lightly loaded.
Do I need to replace hangers and bushings when changing springs?
While not always mandatory, we strongly recommend replacing hangers and bushings whenever you change springs. Worn hangers can cause premature spring failure and alignment issues. Our complete kits include new hangers, bushings, and U-bolts, saving you from potential comebacks. If your existing hangers show any cracks, elongated bolt holes, or excessive rust, replacement is essential for safety and proper spring function.
