Frequently Asked Questions About International S2200-S2600 Leaf Springs-Hangers-Acc

What years and models of International S2200-S2600 trucks are these leaf springs compatible with?

Our leaf springs and hangers are designed to fit International S2200-S2600 series trucks manufactured from 1989 through 2004. This includes all variations such as the S2554, S2574, and S2674 models. Always verify your specific VIN and axle configuration before ordering, as some specialty configurations may require different components. If you're unsure about compatibility, contact our support team with your truck's VIN number for exact fitment verification.

What weight capacity should I choose for my leaf springs?

The correct weight capacity depends on your truck's GVWR and typical load requirements. Most S2200-S2600 models use springs rated between 12,000-20,000 lbs per axle. Check the door jamb sticker or original spring pack for capacity ratings. For vocational trucks or those frequently carrying maximum loads, we recommend choosing springs rated at or slightly above your maximum axle weight. Under-rated springs will sag prematurely and affect ride quality, while over-rated springs may create a harsh, bouncy ride when unloaded.

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

While leaf spring replacement is possible for experienced DIY mechanics, it requires heavy-duty tools including a floor jack rated for commercial vehicles, jack stands, spring compressors, and torque wrenches capable of 250+ ft-lbs. The job typically takes 4-6 hours per axle. Critical safety concerns include properly supporting the vehicle weight and controlling spring tension during removal. Many customers find it more cost-effective to have a commercial truck shop perform the installation, which typically runs $300-500 in labor per axle.

What's the difference between OEM-style and heavy-duty aftermarket leaf springs?

OEM-style springs match original factory specifications for ride quality and load capacity. Heavy-duty aftermarket options typically add 1-2 extra leaves, increasing capacity by 15-25% but creating a stiffer ride. Heavy-duty springs work well for trucks consistently hauling near maximum capacity or operating on rough terrain. For mixed-use vehicles or highway applications, OEM-style springs provide better ride comfort. All our springs feature shot-peened leaves and anti-friction pads between leaves for extended service life.

How do I know when my leaf springs need replacement versus just new bushings or hangers?

Inspect your springs for these replacement indicators: visible cracks in any leaf, permanent sagging (truck sits 2+ inches lower than spec), leaves that have shifted out of alignment, or broken center bolts. Minor squeaking or slight sagging often only requires new bushings and U-bolts. Hangers should be replaced if they show cracks, elongated bolt holes, or severe rust. A complete spring pack typically lasts 200,000-300,000 miles under normal commercial use, while bushings may need replacement every 100,000-150,000 miles.
