Frequently Asked Questions About International PayStar 5000 Steer Axle Springs & Hangers

What years and models of International PayStar 5000 are these springs and hangers compatible with?

These steer axle springs and hangers are designed to fit International PayStar 5000 models from 2003 through 2018. However, compatibility can vary based on your specific axle configuration and GAWR (Gross Axle Weight Rating). We recommend checking your VIN or contacting us with your truck's specifications to ensure proper fitment, especially if you have a specialized vocational setup or aftermarket modifications.

What weight ratings are available, and how do I know which spring capacity I need?

Spring capacities typically range from 12,000 to 20,000 pounds per axle, with the most common being 14,600 lb and 16,000 lb ratings for PayStar 5000 applications. To determine your needs, check the door jamb sticker for your front GAWR or look at your existing spring pack for stamped numbers. If you're experiencing sagging or planning to add heavy equipment like a snow plow, consider upgrading to a higher capacity spring pack.

How difficult is the installation, and what special tools are required?

Installation typically takes 4-6 hours per side for experienced mechanics. You'll need a heavy-duty jack, spring compressor, torque wrench capable of 450-500 ft-lbs, and proper safety stands. The most challenging part is safely compressing and removing the old springs. Many customers report needing to heat and cut seized U-bolts and pins. We strongly recommend professional installation unless you have experience with heavy truck suspension work and access to a properly equipped shop.

What's the difference between OEM and aftermarket options in terms of quality and longevity?

OEM springs typically use higher-grade 5160H steel and come with a better warranty, lasting 500,000+ miles under normal conditions. Quality aftermarket options from established manufacturers like Dayton Parts or Triangle Suspension can perform comparably at 60-70% of OEM cost, though they may show wear 10-20% sooner. Avoid budget imports that often use inferior steel and lack proper heat treatment, leading to premature sagging or cracking within 100,000 miles.

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

While springs and hangers can technically be replaced separately, we recommend replacing them as a set when either component shows significant wear. Worn hangers can cause premature spring failure due to improper alignment and stress points. Look for hanger bushing wear, cracks, or elongated bolt holes. If your hangers show these signs when replacing springs, spending the extra money now will prevent comeback issues and ensure proper suspension geometry.
