⚡ At a Glance
- • Durability: Manufactured from steel with a zinc-plated coating to resist rust and wear
- • Best for: Owners of 2000–3500 lb trailers needing replacement outer hub caps
- • Not ideal for: Hubs with a different outer diameter than 50.4mm/1.98inch
Zinc-plated steel caps made for 50.4mm (1.98 inch) hub openings. Designed to fit most 2000–3500 lb trailer axles including common 4- and 5-lug setups.
Secure Fit – With 50.4mm/1.98in outer diameter precision
Outer diameter specified at 50.4mm/1.98inch creates an interference fit that sits tightly in hub openings. A snug fit reduces the chance of caps popping out during towing.
Accurate sizing keeps bearings covered and helps prevent moisture and grit entry. A rubber mallet is recommended for final installation to ensure a firm seat.
Corrosion Resistance – Thanks to zinc-plated steel construction
Steel base gives structural strength while the zinc plating acts as a sacrificial layer to slow rust and surface wear. The finish reduces direct metal exposure to road moisture.
Zinc-plated surfaces prolong service life in wet or salty conditions. Regular inspection will keep seals effective over multiple seasons.
Broad Axle Compatibility – With fit for standard 2000–3500 lb hubs
Designed to suit most brake and idler trailer axles rated between 2000 and 3500 pounds and common 4-lug and 5-lug hub patterns. Compatible with many standard and EZ Lube arrangements though commonly used on non-EZ Lube hubs.
Matches a wide range of small trailer setups so replacements are straightforward. Confirm outer diameter before fitting to avoid mismatches.
