International 9300/9370 Hub Adapters

Frequently Asked Questions About International 9300/9370 Hub Adapters

What do hub adapters do on an International 9300/9370?

Hub adapters allow you to mount a different style or size of wheel hub assembly onto the axle spindle than what the truck originally came with. They bridge the gap between the axle spindle and the hub/bearing setup, letting you adapt to different hub configurations, such as switching between different bearing types or hub styles, without replacing the entire axle spindle.

How do I know if a hub adapter will fit my specific International 9300 or 9370?

Fitment depends on your truck's axle spindle diameter, bearing configuration, and the specific hub style you're adapting to or from. Because International 9300/9370 trucks were built across multiple years with different axle and hub combinations, it's important to confirm your axle manufacturer, spindle dimensions, and current hub setup before ordering. If you're unsure, check your axle tag information or reach out to our team with your VIN or axle specs for confirmation.

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

Hub adapters in this category are typically made from heat-treated steel to handle the constant stress, heat, and load placed on wheel-end components. Quality varies by manufacturer, so look for adapters that specify the steel grade or heat-treatment process used, as this affects long-term durability under regular highway use.

Can I install a hub adapter myself, or should I have a professional do it?

Installing a hub adapter involves working with wheel-end components, bearings, and seals, all of which require precise torque specs and proper alignment to function safely. While experienced DIY mechanics with the right tools can complete this job, we recommend having a qualified technician handle the installation, especially the bearing adjustment and seal seating, since improper installation can lead to premature wheel-end failure.

Will using a hub adapter affect my wheel bearing warranty or maintenance intervals?

Adapting a hub to a configuration outside the manufacturer's original spec can sometimes affect bearing warranty coverage, so it's worth checking with your bearing or hub manufacturer before installation. Additionally, after installing a hub adapter, it's a good practice to recheck bearing adjustment and seal integrity sooner than your normal maintenance interval to make sure everything has settled in properly.
