What's IncludedEach package contains:- 4 zinc-coated steel dust caps (2.72 inches / 69.1mm outer diameter)- 4 rubber plugs for immediate installation- 4 additional backup seals for future replacementThis complete 8-seal configuration ensures you have spare parts readily available during long trips or remote camping adventures, minimizing downtime when maintenance is needed.Heavy-Duty ConstructionManufactured from premium zinc-coated steel, these dust caps deliver superior resistance to:- **Corrosion**: Zinc coating provides a protective barrier against rust and oxidation, even in wet or salty conditions- **Deformation**: Reinforced steel construction maintains structural integrity under vibration and impact- **Moisture intrusion**: Precision-engineered fit creates an effective seal against water and dust penetrationThe durable materials are selected to withstand harsh road conditions, extreme temperatures, and constant exposure to the elements commonly encountered during RV travel and trailer towing. Wide CompatibilityThese dust caps are designed to fit:- Most standard 7000-8000 lb trailer wheel hubs- 8 on 6.5" bolt pattern trailer axles- Dexter EZ Lube axle systems- Standard (non-EZ Lube) axle configurations- Camper trailers and recreational vehicles (RVs)- Utility trailers and cargo haulers**Important**: Please measure your existing dust cap outer diameter carefully before ordering. The 2.72 inch (69.1mm) measurement must match your hub specifications for proper fitment.Easy InstallationInstallation requires no special tools or technical expertise:1. Remove the old dust cap by pulling it straight off the hub2. Clean the hub surface to ensure a proper seal3. Insert the new rubber plug into the dust cap opening4. Press the new dust cap firmly onto the hub until fully seatedThe direct-fit design allows for quick replacement without modifying your existing axle components. For optimal performance, consider replacing all four dust caps simultaneously to ensure uniform protection across all wheels.Why Regular Dust Cap Maintenance MattersWheel hub dust caps serve as the first line of defense for your trailer's bearing system. When dust caps become damaged, cracked, or loose, they allow:- Dirt and abrasive particles to enter the bearing assembly- Moisture to cause rust and corrosion on internal components- Grease contamination leading to accelerated wear- Premature bearing failure requiring costly repairsBy maintaining intact dust caps with secure rubber plugs, you protect your investment in quality wheel bearings and reduce the frequency of repacking or replacement.Technical Specifications- **Outer Diameter**: 2.72 inches (69.1mm)- **Material**: Zinc-coated steel- **Quantity**: 4 dust caps + 8 rubber seals (4 installed + 4 backup)- **Weight Capacity**: Compatible with 7000-8000 lb trailer axles- **Bolt Pattern**: Fits 8 on 6.5" configurations- **Compatibility**: Dexter EZ Lube and standard axles Quality AssuranceEach dust cap undergoes rigorous quality control inspection before shipment to verify:- Accurate dimensional tolerances for proper fit- Uniform zinc coating coverage without defects- Secure rubber plug retention- Structural integrity free from cracks or deformitiesWe stand behind our products and offer responsive customer support.
