Frequently Asked Questions About International WorkStar Hub Adapters

Will these hub adapters fit my specific International WorkStar model year?

Our International WorkStar hub adapters are designed to fit WorkStar models from 2008-2017. However, compatibility can vary based on your specific axle configuration and wheel setup. Most adapters work with standard 10-lug hub patterns, but we recommend checking your existing hub bolt pattern and pilot diameter before ordering. If you're unsure, contact us with your VIN and we can verify the correct adapter for your truck.

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

Our WorkStar hub adapters are precision-machined from 6061-T6 aluminum alloy, which provides excellent strength while keeping weight down. Standard thickness options range from 1.5 inches to 3 inches, depending on your spacing needs. Each adapter is hub-centric to ensure proper load distribution and includes Grade 8 studs rated for commercial truck applications. The aluminum construction resists corrosion better than steel alternatives while maintaining the durability required for heavy-duty use.

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

Installation requires basic hand tools including a torque wrench, socket set, and thread locker. While many customers successfully install these themselves, proper torque specifications are critical - typically 450-500 ft-lbs for the main hub bolts. You'll need to re-torque the bolts after the first 50-100 miles of driving. Professional installation is recommended if you're not comfortable working with high-torque applications or don't have access to a commercial-grade torque wrench.

Can I run dual wheels with these adapters, and what about weight ratings?

Yes, our hub adapters are engineered to support both single and dual wheel configurations. Each adapter is load-rated up to 7,500 lbs per wheel position, which exceeds most WorkStar applications. When running duals, ensure your adapter thickness accounts for proper spacing between the inner and outer wheels. The adapters maintain the original hub's weight rating when properly installed and torqued to specification.

Will these adapters affect my speedometer accuracy or cause vibration issues?

When properly installed, our hub-centric adapters should not cause any vibration issues. The precision-machined centering ring ensures perfect alignment with your hub. Speedometer accuracy is only affected if you're changing tire diameter, not by the adapter itself. Some customers report slight changes in handling feel due to the increased track width, but this is typically seen as an improvement in stability. Always ensure wheels are balanced after installation to prevent any vibration.
