Frequently Asked Questions About International 8100-8300 Hub Adapters

Will these hub adapters fit my specific International truck model and year?

These hub adapters are designed specifically for International 8100, 8200, and 8300 series trucks manufactured from 1989 through 2004. They work with both steel and aluminum wheels. Before ordering, verify your truck's model number and year, as International made slight hub variations across different production years. If your truck falls outside this range or you have a different International series, these adapters will not be compatible.

What material are these hub adapters made from, and how durable are they?

Our International 8100-8300 hub adapters are precision-machined from high-grade steel or aluminum alloy, depending on the specific model you choose. The steel versions feature a corrosion-resistant coating that holds up well against road salt and weather exposure. Based on customer feedback, these adapters typically last 5-10 years with regular maintenance. The aluminum versions are lighter but equally durable, making them ideal for weight-conscious applications.

Do I need special tools or professional installation for these hub adapters?

Installation requires basic hand tools including a torque wrench, socket set, and jack stands. Most experienced DIY mechanics can complete the installation in 2-3 hours per axle. However, proper torque specifications are critical - front hub adapters require 450-500 ft-lbs and rear adapters need 250-300 ft-lbs. We strongly recommend having a certified mechanic perform or verify the installation, as improper mounting can cause wheel separation. Always re-torque after the first 50-100 miles of driving.

What finishes are available, and which one resists rust the best?

We offer three finish options: raw steel (requires painting), black powder coat, and chrome. The black powder coat finish provides the best long-term rust protection and is the most popular choice among commercial drivers. Chrome looks great initially but requires more maintenance to prevent pitting and corrosion, especially in northern climates. Raw steel must be painted immediately after installation to prevent rust.

Why are my current hub adapters causing vibration, and will new ones fix this issue?

Vibration typically occurs when hub adapters become warped from overtightening, impact damage, or age-related wear. Our replacement adapters are balanced to within 0.005 inches to eliminate vibration issues. However, vibration can also stem from bent wheels, worn wheel bearings, or damaged hubs. Before purchasing new adapters, have your wheels professionally checked for runout and ensure your wheel bearings are in good condition. New adapters will only solve vibration if your current adapters are the root cause.
