Freightliner Coronado Leaf Springs, Hangers & Acc.

Frequently Asked Questions About Freightliner Coronado Leaf Springs, Hangers & Acc.

Will these leaf springs fit my specific year model Freightliner Coronado?

Our leaf springs are designed to fit Freightliner Coronado models from 2001 through 2021. However, there are variations based on whether you have a day cab or sleeper configuration, and whether your truck has a single or tandem axle setup. When ordering, you'll need to know your truck's exact year, VIN number, and suspension type (Hendrickson, Freightliner Airliner, or Reyco). We recommend checking your existing leaf spring part numbers or contacting our support team with your VIN for guaranteed fitment.

What's the typical lifespan of aftermarket leaf springs compared to OEM?

Quality aftermarket leaf springs typically last 150,000 to 250,000 miles under normal commercial use, which is comparable to OEM specifications. The lifespan depends heavily on load conditions, road quality, and maintenance. Our heavy-duty leaf springs are manufactured from 5160H spring steel and undergo shot peening for stress relief, matching or exceeding OEM durability. Signs you need replacement include sagging ride height, uneven tire wear, or visible cracks in the leaves.

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

While leaf spring replacement is possible for experienced mechanics, it requires specific equipment including a heavy-duty floor jack, jack stands rated for commercial trucks, spring compressors, and torque wrenches capable of 450-500 ft-lbs. The job typically takes 4-6 hours per side. Safety is critical as you're working with components under extreme tension. Most customers opt for professional installation, which runs $300-500 per axle at most truck service centers.

What's included with leaf spring hangers and shackle kits?

Our complete hanger kits include the front spring hanger brackets, rear shackle hangers, grade 8 mounting bolts, and bushings. Shackle kits come with heavy-duty shackles, greaseable pins, and polyurethane or rubber bushings depending on your selection. Some applications require frame reinforcement plates, which are sold separately. Note that spring eye bushings and center pins are typically not included with the springs themselves and must be ordered based on your specific spring eye diameter (either 2-inch or 2.5-inch).

How do I know if I need heavy-duty or standard capacity leaf springs?

Check your door jamb sticker for your truck's GAWR (Gross Axle Weight Rating). Standard leaf springs are suitable for typical highway hauling up to the factory GAWR. Heavy-duty springs are recommended if you frequently haul at maximum capacity, operate on rough roads, or have added equipment like heavy winches or crane bodies. Heavy-duty options typically add 2-3 additional leaves and increase capacity by 2,000-4,000 pounds per axle. Overspringing can cause a harsh ride when empty, so match capacity to your actual hauling needs.
