Frequently Asked Questions About International S1700-S1900 Steer Axle Springs & Hangers

What specific International truck models and years are these steer axle springs compatible with?

These steer axle springs and hangers are designed for International S1700, S1800, and S1900 series trucks manufactured from 1989 through 2001. They fit both single and tandem axle configurations. Always verify your truck's exact model number and VIN before ordering, as some late-model S1900s may have different specifications. If you're unsure about compatibility, check your existing spring's part number or contact us with your VIN for verification.

What weight capacity should I choose for my steer axle springs?

Steer axle spring capacity typically ranges from 12,000 to 20,000 pounds for these International models. The correct capacity depends on your truck's configuration and typical load. Standard S1700 models usually require 12,000-14,000 lb springs, while heavier S1900 dump trucks and heavy haulers may need 16,000-20,000 lb capacity. Check the data plate on your truck's door jamb for the front GAWR (Gross Axle Weight Rating) to determine the appropriate spring capacity.

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

While experienced mechanics can install steer axle springs, the job requires heavy-duty spring compressors, proper jack stands rated for commercial trucks, and impact tools capable of handling grade 8 bolts. The process involves safely supporting the truck frame, compressing the old springs for removal, and aligning new hangers precisely. Most customers find it safer and more cost-effective to have a commercial truck shop perform the installation, which typically takes 3-4 hours for both sides.

What's the difference between standard and heavy-duty spring hangers?

Standard hangers are typically 3/8" thick steel and work well for highway and moderate-duty applications. Heavy-duty hangers feature 1/2" thick steel construction and reinforced mounting points, making them ideal for vocational trucks, dump trucks, or vehicles frequently operating on rough terrain. Heavy-duty hangers also use larger bushings that last longer under severe conditions. If your truck experiences frequent spring hanger wear or cracking, upgrading to heavy-duty hangers is recommended.

How can I tell if my steer axle springs need replacement?

Common signs include visible sagging (truck sits lower in front), uneven tire wear on steer tires, excessive bouncing or harsh ride quality, visible cracks or breaks in spring leaves, and worn or damaged spring eyes. Measure the distance from the frame to axle on both sides - a difference greater than 1/2" indicates spring wear. Also check for broken center bolts, shifted leaf packs, or worn shackle bushings. If you notice any of these issues, replace springs in pairs to maintain proper alignment and handling.
