Frequently Asked Questions About International 8600 TranStar Drive Axle Springs & Hangers

What years and models of International 8600 TranStar are these drive axle springs compatible with?

These drive axle springs and hangers are designed to fit International 8600 TranStar models from 2007-2017. However, compatibility can vary based on your specific axle configuration (single vs. tandem), GVWR rating, and suspension type. We recommend checking your truck's VIN or contacting our support team with your truck's build sheet to ensure proper fitment before ordering.

Are these springs OEM replacements or aftermarket, and what's the difference in quality?

We carry both genuine OEM International springs and high-quality aftermarket alternatives. OEM springs match factory specifications exactly but come at a premium price. Our aftermarket options are manufactured to meet or exceed OEM standards, using heat-treated spring steel with proper shot-peening for durability. Many customers report aftermarket springs lasting just as long as OEM when properly installed and maintained.

What tools and experience level are needed to replace drive axle springs and hangers?

Replacing drive axle springs requires heavy-duty equipment including a minimum 20-ton jack, proper jack stands rated for commercial vehicles, spring compressors, and impact tools. This is not a DIY job for most drivers - it requires mechanical experience and safety knowledge. The truck must be properly supported, and springs are under extreme tension. Most customers have this work performed at a qualified heavy-duty shop to ensure safety and proper alignment.

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

Common signs include visible cracks or breaks in the spring leaves, uneven tire wear on drive axles, sagging on one side of the truck, separated or shifted spring leaves, and worn or damaged spring eye bushings. Additionally, if your truck sits lower than normal or you're experiencing harsh ride quality and excessive bouncing, your springs may be worn. Regular inspection during PM services can catch issues before complete failure.

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

A complete kit typically includes the multi-leaf spring pack, front and rear spring hangers, pivot pins, and bushings. However, you may also need new U-bolts, spring mounting hardware, shackles, and shock absorbers depending on your truck's condition. Many customers also replace worn equalizers and torque rods during spring service. Check the product description carefully or call us to confirm what's included in your specific kit.
