Frequently Asked Questions About International LT Drive Axle Springs & Hangers

Will these springs and hangers fit my specific International LT model year?

These drive axle springs and hangers are designed for International LT models from 2017 to present. However, compatibility can vary based on your truck's specific configuration, including whether you have a single or tandem axle setup, and your suspension type (air ride or spring). We recommend checking your VIN or calling our technical support team at 1-888-875-7787 with your truck's details to ensure proper fitment before ordering.

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 spring rates for your specific truck configuration. Aftermarket options often provide comparable performance at a lower price point and may offer heavy-duty upgrades for trucks with consistent heavy loads. If you're maintaining warranty coverage or need exact factory ride characteristics, choose OEM. For cost savings or upgraded capacity, quality aftermarket brands like Dayton Parts or Triangle Suspension Systems are reliable alternatives.

How difficult is it to replace drive axle springs and hangers, and what tools do I need?

Replacing drive axle springs and hangers is an intermediate to advanced job that typically takes 3-5 hours per side. You'll need a heavy-duty jack and jack stands rated for commercial trucks, spring compressors, impact wrenches, and proper safety equipment. The most challenging part is safely compressing and removing the old springs under load. Many drivers choose professional installation due to safety concerns, as improper installation can lead to catastrophic failure. If you're experienced with heavy truck maintenance and have the proper equipment, detailed installation instructions are included with most kits.

How do I know when my drive axle springs or hangers need replacement?

Common signs include visible cracks or breaks in spring leaves, excessive rust or corrosion, uneven tire wear on drive axles, a sagging rear end when loaded, or clunking noises from the suspension during turns or over bumps. Hangers should be inspected for elongated bolt holes, cracks at stress points, or bent brackets. During DOT inspections, broken or cracked springs are out-of-service violations, so regular visual inspections during pre-trip checks are essential. Most springs last 300,000-500,000 miles under normal conditions, but severe-duty applications may require more frequent replacement.

Do I need to replace springs and hangers together, or can I replace them separately?

While you can technically replace springs and hangers separately, it's strongly recommended to replace them as a complete kit. Worn hangers can cause premature spring failure, and new springs on worn hangers won't perform properly and may lead to alignment issues. Additionally, the labor involved in accessing these components makes it cost-effective to replace both at once. Most of our kits include matched springs and hangers with new bushings and hardware, ensuring all components work together properly and saving you from repeat repairs.
