Quick fix

Easily Installed with no modification in under a minute. The finish was a little glossier, then OE.

Identical to originals at 1/4 of the price.
This is a review on the Kawaski KRX wheel hub covers. I am very impressed. These are identical in look to the OEM Kawasaki KRX hub covers. Those cost over $28.00 for just one. This is a 4 pack for less than that price. The okastic quality is the same and these fit the machine perfectly. We got them to replace as the others break and fall off and you can not tell which one is new compared to the old ones. Overall great buy and identical to the original. Highly recommend.

Fit supper snug!
Awesome product. I lost 2 of them on my Kawasaki Teryx 1000, and these caps fit super snug. I almost didn't think they fit because they were so tight, and had to use a rubber mallet to gentle tap them on. Worth the buy!

Happy with the price and quality!
Size: Single Slat, Color: Matte Black, Size: Single Slat, Color: Matte Black
I bought this set with low expectations to replace my OEM grill which was falling apart and getting loose. I thought, not much to lose. They actually turned out to fit and look great. Just one tip-- when installing, be sure that you are correctly positioning the tension clips to be in contact with the end of the hood notch. There are a lot of Youtube guides you can find online to help you with it. Otherwise, they will just be totally loose and not fit correctly.
