Today we're taking a look at the Phoenix USA baby moon hub cover. The baby moon style center cap gives your trailer wheel a unique throwback appearance. Has really nice chrome plating to offer a nice look. It's constructed from sturdy stainless steel construction, which provides durability, rust, and corrosion protection.It's a simple snap in installation. With this part number you get one hubcap. It's designed to fit 13 inch, 14 inch and 15 inch steel conventional wheels and wheels with the bolt pattern of five on four and a half inches, or six on six and a half inches.Now this classifies as an 11 inch diameter cover, but if we put a ruler on here, we can see that outer edge to outer edge, directly at the center, measures about 10 and a half to 10 and 9/16 inches in overall diameter.
And from the very front of the unit to the very back of the unit, so this would be the overall depth, it measures about three and 1/8 inches to three and 3/16 of an inch. Right in that area. That's going to do it for today's look at the Phoenix USA baby moon hub cover.
They fit even with my vintage hubs covers! Can’t change the hubs bc the axle is vintage and nothing modern fits. Can’t change the axle bc that’s a huge/hard job! Had to find baby moons that fit with the vintage hubs covers cover (sticks out about 2.5” from lip that hold baby moons on). Finally! These fit! Hope they come off as easy as they went on. Fit feels snug, don’t think they’re going to come off going down the road. Installed on 15” wheels from etrailer.
These caps fit my wife's 1971 Shasta 16SC trailer perfectly. After several camping trips, they remain shiny and new.

After a year, these hub caps are hanging on well and still look shiny and new!
These Baby moons were exactly what I was looking for. I tried other vendors, but the Baby Moons they sent did not fit. They were either the wrong style or wrong size. Their online descriptions were not adequate to determine the correct style and fit. The package came in a timely manner, and I found the agent on the phone to be friendly, knowledgeable and helpful. I would certainly recommend ETrailer.
These fit 10.25 hupcap nubs perfect. Driven a few hundred miles and they are snug. They look great on here as well.
Excellent fit perfectly on my vintage trailer rim.
These hubcaps fit my 6-lug 15" wheels perfectly. I ordered some previouslyf from E-bay but they were 1/4" in diameter too small even though they stated they fit 10 1/2" diameter wheel centers. These caps popped right on with little effort yet fit snuggly with no play. These are the right product for 15" six lug wheels with 10 1/2" wheel center nubs.

These hubcaps have been on my hot rod for a year now and look good-as-new. Very nice product.
These hubs fit perfectly on my 1984 Gore Horse Trailer. The rims are 15" x 6" with a 5 on 4 1/2" bolt pattern. The inside clear diameter of these baby moon hubs are right around 10 1/8" - 10 1/4" and fit very snugly on the mounting tabs of my wheels. Shout out to etrailer customer service for recommending the correct hubs!
Good quality. Fit my horse trailer wheels perfectly.
Perfect fit for my 69 Aristocrat. Good quality and easy to install.
Good fit great look. Fast shipping

Glad we could help keep your vintage camper keep its super snazzy look! Older camper had so much more style to them than the new ones do, so I am always happy to see when people restore and use them. Especially when they look this good! ^___^ What are you towing your camper with?
