NO Stars!!! I give it ZERO STARS!!!
Is there an alternative to these center caps? They are absolute junk. I have gone through three so far. I love the look of the wheels but this is joke of a cap. The plastic tabs break off and the wire is not a good solution, and the center emblem falls out. My Jeep is by no means out hard core wheelin', I feel bad for the guys who do. No wonder these are always on back order.Helpful (0)

Unfortunately the item is backordered. These are to be replacements, my original caps are nice looking, but I have read several comments from people losing them. I suggest putting a small spot of black silicone adhesive between the cap and wheel to help secure it. Shouldn't be a problem when you need to take it off.Helpful (0)

The materials that this product is made is not durable, you can see the center caps flying in no time, I purchased at least 4 pcs. to replace the originals that came with the wheels, only to loose them again.Helpful (0)

mammoth hub cap replacement
The product is a match for the original caps however... the caps are held in place by a retaining wire ring and several plastic tabs. One of the caps had 3 of the tabs broken off. I wound up using clear silicon adhesive to glue it in place.Helpful (0)

Mammoth Center Cap
I had recently lost one of my center caps on the trail and had searched everywhere for a replacement without any luck. Luckily Extreme Terrain carries them. The product arrived on time is works perfectly. It matches all my other center caps. Couldn’t be happierHelpful (0)

They replaced a broken cap. They do have problems: center emblem falls out and paint dulls after only a few washing.Helpful (2)

These are the stock caps that came with the wheels. These caps come off very easily which is why I've lost three in a little over a year. I use a long brush to wash my Jeep and they fall off just about every time I hit with brush. The design needs improvement. Also when I ordered they were on back order for months. Not satisfied.Helpful (5)

Is there another center cap that can be used on Mammoth 8 rims as these will not be available for 7-8 weeks?
Will my stock "Jeep" center caps fit the Mammoth Boulder rim center bore holes? Thanks
No, stock center caps will not fit Mammoth wheels.
I bought my ‘16 Wrangler used with Mammoth wheels and these center caps. I’ve lost two center caps to date. I see similar complaints in the reviews. The three remaining center caps seems to be pretty secure, but how do you keep these in place without falling off? I would like to purchase to replace the lost two, but not if they will keep falling off.
To have these stay in better, you can press the metal ring together on the back of the center cap in for a tighter fit.
I just bought a used 2009 Jeep Wrangler X that has the Mammoth 8 wheels in 17x9. These wheels don't have center caps. Will any of the Mammoth center caps fit?
These are for use with the Mammoth 8 Aluminum Wheels.
At this time we do not have dimensions on this center cap as it is designed as a direct replacement for the Mammoth 8 wheel.
Unfortunately the metal ring for the Mammoth 8 Center Cap is not sold separately.
That metal ring would be placed on the outside of the plastic tabs on the center cap. The metal ring helps to secure the center cap in the wheel.
