Frequently Asked Questions About International S2200-S2600 Drive Axle Springs & Hangers

What years and models do these springs and hangers fit?

These drive axle springs and hangers are designed specifically for International S2200, S2300, S2400, S2500, and S2600 series trucks manufactured from 2002 to 2017. They're compatible with both single and tandem axle configurations. Always verify your truck's specific model year and axle configuration before ordering, as some variations may exist between early and late production years.

What's the difference between OEM and aftermarket springs, and which should I choose?

OEM springs are manufactured to International's exact specifications and typically use higher-grade steel with precise heat treatment. Aftermarket options vary in quality - premium aftermarket brands often match OEM specifications at a lower price point, while budget options may use lighter gauge steel or less durable coatings. For heavy-duty commercial use, we recommend OEM or premium aftermarket brands. For lighter applications or budget-conscious repairs, quality aftermarket options can provide good value.

How difficult is the installation, and what tools do I need?

Installing drive axle springs and hangers requires intermediate to advanced mechanical skills and proper equipment. You'll need a heavy-duty jack or lift system, spring compressors, impact wrenches, and torque wrenches. The job typically takes 4-6 hours per axle for experienced mechanics. Critical safety note: improperly compressed springs can cause serious injury. We strongly recommend professional installation unless you have experience with heavy truck suspension work.

How can I tell if my springs or hangers need replacement?

Common signs include: visible cracks or breaks in spring leaves, excessive rust or corrosion, uneven tire wear, sagging ride height on one side, clunking noises over bumps, and worn or elongated hanger bolt holes. During inspection, look for separated leaves, missing or broken center bolts, and shiny spots indicating metal-on-metal contact. If you notice any of these issues, replacement is necessary to prevent catastrophic failure.

What's included in a complete spring and hanger kit, and what else might I need?

Complete kits typically include the leaf spring assembly, front hanger, rear hanger or shackle, and mounting hardware (U-bolts, nuts, and bushings). However, you may also need to purchase separately: spring pins, shackle pins, torque arm bushings, and new U-bolt plates if yours are worn. Some installations also require new shock absorbers and air bag components if equipped. Check your specific kit contents carefully to ensure you have all necessary components before beginning installation.
