GREPSPUD Trailer Hub Dust Caps 2.44" (4-pack) Zinc-Plated Steel with Removable Rubber Plugs — Fits 5200–6000 lb, 6 on 5.5"

GREPSPUD 2.44" trailer hub dust caps are a four-piece zinc-plated steel set with four spare rubber plugs, built to seal grease, keep out dirt, and resist corrosion on 5200–6000 lb trailer hubs.

These hub caps are made to fit most 5200–6000 lb trailer wheel hubs, including both EZ-Lube and standard axles with a 6 on 5.5" bolt pattern. Manufactured from carbon steel with a zinc-plated finish and supplied with removable rubber plugs, the set gives you a straightforward way to protect bearings and extend the life of your trailer’s wheel assembly. The kit includes extra seals so you have immediate replacements if a plug wears or is lost during service.

How do these caps protect trailer bearings?

The GREPSPUD caps seal the hub cavity and slow contamination from water, grit, and road debris, helping to preserve the grease around bearings. Their removable rubber plugs make it easy to top up lubricant without removing the entire cap.

• Seals out moisture and particles that cause corrosion and wear
• Removable rubber plug allows grease access for maintenance
• Zinc-plated carbon steel resists rust for longer service life

Will these fit my trailer axle and how do I install them?

The caps measure approximately 2.44 inches (OD 2.46 in / 62.5 mm) and are intended for most 5200–6000 lb hubs, compatible with common EZ-Lube and standard axles. They are slightly oversized by design to ensure a tight press fit; use a wood block and hammer or a rubber mallet to seat them evenly without denting.

• Check OD (2.46" / 62.5 mm) against your hub bore before ordering
• Press or gently tap into place using a wood block to protect the cap
• Fits 6 on 5.5" bolt pattern hubs and most 5200–6000 lb trailer wheels

What materials and features make these durable?
