Background

Human Siglec-2, also known as B cell antigen CD22 or B lymphocyte cell adhesion molecule (BL-CAM), is a B cell restrictive glycoprotein that is expressed in the cytoplasm of progenitor B and pre-B cells and on the surface of mature B cells. CD22 mediates the interaction between B cells and may participate in the localization of B cells in lymphoid tissue. Siglec-2/CD22 binds to sialylated glycoproteins and plays a role in positive regulation by interacting with the Src family tyrosine kinases. It may also act as an inhibitory receptor by recruiting cytoplasmic phosphatase through its SH2 domain, blocking signal transduction through dephosphorylation of signaling molecules.

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.

Easy install !! They fit well and look good
Size: Single Slat, Color: Chrome
The grill is plastic of course but for the price it makes the car look good. I had a cracked grill and it looked so ugly. These popped right in easy install and makes the car look good again I am happy.
