• 1. Measure Before Ordering – 1.98" OD Fits 2000–3500 lb Axles​ – Outer diameter 1.98" (50.4 mm), height 1-7/16". Engineered for 4-lug and 5-lug hubs on most travel trailer, boat trailer, camper, and RV axles. Compatible with Dexter EZ Lube systems and standard brake/idler axles. Verify your current cap OD with calipers before purchase—common sizes are 1.98", 2.44", and 2.72".
• 2. Complete 2-Pack + 2 Spare Plugs​ – Includes 2 dust caps plus 2 extra rubber grease plugs (4 plugs total). The spare plugs let you reseal after checking grease or topping off, without hunting hardware mid-trip. One 2-pack covers one axle side (2 wheels); most tandem-axle trailers need 2 packs.
• 3. Carbon Steel + Zinc-Plated Finish​ – Reinforced carbon steel body with corrosion-resistant zinc plating stands up to road salt, coastal humidity, and launch-ramp splash. Rubber-sealed rim keeps grease in and grit out so your wheel bearings stay protected between services.
• 4. Built for Boat, Camper & RV Use​ – From saltwater flats boats to cross-country fifth-wheel hauls, these caps are sized for the axles that see the most launch-cycle corrosion. A direct replacement when your factory caps crack, loosen, or disappear into the lake bottom.
• 5. 10-Minute Hand-Tool Install​ – Press or drive in with a wood block and hammer, or use a socket and press. No specialty tools, no modification to the hub. All you need is already in the box.
