Overview
Seal your commercial trailer's wheel ends and prevent catastrophic bearing contamination with this premium 6 Hole Trailer Hub Cap by FleetPro Parts & Tires. Manufactured to strict Fleet Standard specifications, this heavy-duty diecast aluminum cap is designed for universal trailer axles running either oil or grease bath lubrication. A cracked, leaking, or improperly sealed hub cap will quickly lead to bearing failure, wheel lockup, and expensive on-road breakdowns. We stock these heavily right here in our Hanover Park, Illinois warehouse to ensure lightning-fast shipping for fleets, diesel repair shops, and owner-operators nationwide.
Leak-Free Wheel End Protection: The 6 Hole Trailer Hub Cap Advantage
This 6 Hole Trailer Hub Cap (Part # 180.10629) is engineered for long-lasting durability in severe-duty environments. Measuring 2.688 inches in height, it features a standard 6-bolt mounting pattern with a 5.500-inch bolt hole circle diameter. This specific model is designed without a side fill plug, offering a clean, tamper-resistant seal for mechanics who prefer to fill through the center window. The rugged diecast aluminum body resists warping and cracking, ensuring your wheel seal maintains perfect integrity.
As we continue to build the largest inventory of commercial truck parts in Illinois, we prioritize wheel-end hardware that offers reliable, "bolt-on" aftermarket performance. Serving as a professional-grade replacement for heavily searched part numbers like Stemco 340-4009, SKF C40-4009, and National 340-009, this hub cap is an essential part of any brake or bearing service. Manufactured by Automann, it delivers the rugged durability your fleet demands. Pro Tip: Need the version with a side fill plug? Use part # 180.10619. For a replacement window kit, use 180.10620.
