Frequently Asked Questions About International S2100-S2300 Hub Adapters

Will these hub adapters fit my specific International S2100, S2200, or S2300 model year?

These hub adapters are designed to fit International S2100, S2200, and S2300 series trucks manufactured from 1989 through 2010. They work with both manual and automatic locking hub systems. However, we strongly recommend verifying your specific hub bolt pattern and spline count before ordering, as International made minor variations throughout these production years. Most models use a 10-bolt pattern with 35 splines, but some specialty configurations may differ.

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

Our International S2100-S2300 hub adapters are precision-machined from high-grade forged steel or aircraft-grade aluminum, depending on the specific model you choose. The steel versions offer maximum durability for heavy-duty applications and harsh weather conditions, while aluminum options provide weight savings for performance applications. Both materials feature corrosion-resistant coatings and are tested to exceed OEM torque specifications by at least 20%.

How difficult is the installation process, and what tools will I need?

Installation typically takes 2-3 hours per side for someone with moderate mechanical experience. You'll need a standard socket set, torque wrench capable of 250 ft-lbs, hub puller, and dial indicator for proper alignment. The most challenging aspect is ensuring proper hub-to-adapter alignment to prevent vibration. We include detailed instructions with torque specifications and alignment procedures. Many customers report success doing this in their driveway, though some prefer professional installation for peace of mind.

What wheel bolt patterns do these adapters convert to, and what backspacing changes should I expect?

Our hub adapters convert from the factory International bolt pattern to common aftermarket patterns including 8x6.5", 8x170mm, and 8x180mm. Each adapter adds between 1.5" to 2" of track width per side, effectively pushing your wheels out. This means you'll need to account for 0.75" to 1" less backspacing when selecting wheels. The added width can improve stability but may require fender modifications on lowered trucks.

Do these adapters affect my truck's warranty, handling, or fuel economy?

Installing aftermarket hub adapters will not void your drivetrain warranty but may affect coverage for wheel bearings and suspension components - check with your dealer for specifics. The wider track width generally improves stability and cornering but increases stress on ball joints and tie rods. Expect a 1-2 mpg decrease in fuel economy due to the increased rotating mass and wider stance creating more aerodynamic drag. Regular inspection of suspension components every 10,000 miles is recommended after adapter installation.
