Frequently Asked Questions About International 4700-4900 Leaf Springs, Hangers & Accessories
What years and models of International 4700/4900 trucks do these leaf springs fit?
Our leaf springs are designed to fit International 4700 and 4900 series trucks manufactured from 1989 through 2009. However, compatibility can vary based on your truck's specific configuration, including GVW rating, wheelbase, and suspension type. We recommend checking your vehicle's VIN or contacting our support team with your truck's year, model, and spring pack specifications to ensure proper fitment.
What's the difference between OEM and aftermarket leaf springs for my International truck?
OEM leaf springs are manufactured to original factory specifications, typically using the same steel alloys and heat treatment processes. Aftermarket options often use upgraded materials like shot-peened steel for improved fatigue resistance. While OEM springs maintain factory ride characteristics, quality aftermarket springs can offer enhanced durability and load capacity at a lower price point. Both options in our inventory meet or exceed DOT standards for commercial vehicle applications.
Do I need special tools or equipment to replace leaf springs on my International 4700/4900?
Yes, leaf spring replacement requires specific tools and safety equipment. Essential items include a heavy-duty floor jack (minimum 20-ton capacity), jack stands rated for commercial trucks, spring compressors, impact wrenches, and proper eye protection. You'll also need a torque wrench capable of 450-500 ft-lbs for U-bolt installation. Due to the weight and tension involved, we strongly recommend professional installation unless you have experience with heavy-duty suspension work.
How do I know when my leaf springs need replacement versus just new hangers or bushings?
Inspect your leaf springs for these replacement indicators: visible cracks in any leaf, separated or shifted leaves, permanent sagging causing uneven ride height, or flat spots where the spring arch has inverted. If springs show minor wear but maintain proper arch, replacing worn hangers, shackles, and bushings may restore performance. Squeaking, loose U-bolts, or minor surface rust typically don't require spring replacement. When in doubt, measure your truck's ride height against factory specifications.
What weight capacity leaf springs should I choose for my International 4700 or 4900?
Spring capacity depends on your truck's application and typical loads. Stock International 4700 springs range from 12,000 to 17,500 lbs capacity, while 4900 models typically use 17,500 to 21,000 lbs springs. For accurate selection, check the spring pack part number on your existing springs or reference your truck's door jamb weight rating sticker. If you frequently haul maximum loads, consider springs rated 10-15% above your regular weight requirements to prevent premature wear.
