Frequently Asked Questions About Kenworth T700 Hub Adapters

What years and models of Kenworth T700 are these hub adapters compatible with?

Our hub adapters are designed to fit Kenworth T700 models from 2010 to present. They're compatible with both standard and wide-base wheel configurations. However, it's important to verify your specific axle manufacturer (Dana, Meritor, or Hendrickson) before ordering, as mounting patterns can vary. If you're unsure about compatibility, check your truck's build sheet or contact us with your VIN for verification.

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

Steel hub adapters are more budget-friendly and extremely durable, typically lasting the lifetime of your truck. They add about 15-20 pounds per wheel but handle heavy loads without issue. Aluminum adapters reduce weight by approximately 40% and resist corrosion better, making them ideal for drivers concerned about fuel economy or operating in high-salt environments. Both options meet DOT standards and carry the same weight ratings.

Can I install these hub adapters myself, or do I need a professional?

While installation is straightforward for those with mechanical experience, we recommend professional installation for safety reasons. The process requires proper torque specifications (typically 450-500 ft-lbs for steel, 475-525 ft-lbs for aluminum), hub-piloted wheel knowledge, and the ability to safely lift the truck. Most installations take 2-3 hours per axle. Always use new studs and nuts when installing, as reusing hardware can compromise safety.

How much do hub adapters extend my wheels outward, and will this affect my turning radius?

Our standard hub adapters add 2 to 4 inches of track width per side, depending on the model you select. This extension improves stability but may slightly reduce your turning radius. The 2-inch adapters typically don't cause clearance issues, while 3-inch and 4-inch options may require fender modifications on some T700 configurations. Check your state's width regulations, as some have restrictions on overall vehicle width.

Do hub adapters affect my warranty or DOT compliance?

Quality hub adapters that meet SAE J694 standards maintain DOT compliance when properly installed. Our adapters are manufactured to these specifications and include proper documentation. Regarding warranty, modifications like hub adapters typically don't void your drivetrain warranty but may affect wheel-end component coverage. We recommend informing your dealer about the modification and keeping all installation documentation. Many fleet operators use these adapters without compliance issues during inspections.
