Frequently Asked Questions About International 9300/9370 Hub Adapters

Will these hub adapters fit my specific International 9300 or 9370 model year?

Our hub adapters are designed to fit International 9300 and 9370 models from 1987 through 2003. However, there are variations between early and late production years. Models from 1987-1994 typically use 5-bolt patterns, while 1995-2003 models commonly use 6-bolt patterns. Always verify your truck's bolt pattern and hub pilot diameter before ordering. If you're unsure, contact us with your VIN and we'll help confirm the correct adapter for your specific truck.

What's the difference between aluminum and steel hub adapters, and which should I choose?

Steel hub adapters are heavier (typically 15-20 lbs each) but offer maximum durability and are ideal for heavy-duty applications or frequent trailer swapping. Aluminum adapters weigh about 40% less, reducing unsprung weight and improving fuel economy, but cost more upfront. For long-haul truckers, aluminum often pays for itself through fuel savings. For local or vocational use where weight isn't critical, steel provides excellent value and longevity.

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

Installation requires basic hand tools including a torque wrench, socket set, and hub puller. The process typically takes 2-3 hours for someone with moderate mechanical experience. Critical steps include properly torquing the adapter bolts to 450-500 ft-lbs and ensuring the pilot surface is clean and free of rust or debris. While many owner-operators successfully install these themselves, we recommend professional installation if you're not comfortable working with wheel hubs or don't have access to a proper torque wrench.

What wheel options do these adapters open up for my International 9300/9370?

These adapters allow you to run modern aluminum wheels with hub-piloted mounting instead of the older stud-piloted steel wheels. This opens up options for popular brands like Alcoa, Accuride, and other 22.5" or 24.5" aluminum wheels. The adapters convert your existing 5 or 6-bolt pattern to accept standard 10-bolt hub-piloted wheels, giving you access to a much wider selection of wheel styles, finishes, and load ratings currently available in the market.

How thick are these adapters and will they affect my track width or tire clearance?

Most hub adapters add between 1.5" to 2" to your track width per side. This spacing can actually improve stability but may cause clearance issues with certain fender configurations or in states with strict width regulations. Before purchasing, measure the clearance between your current tire sidewall and fender lip - you'll need at least 2.5" of space to safely accommodate the adapter. The added width typically doesn't affect turning radius but double-check local regulations if you operate in width-restricted areas.
