That piece is part if the inner wheel liner, same item description if you decide on replacing the rears as well.

You MAY be able to clean and restore them, would be cheaper to attempt that first before spending money to replace.

I would suggest cleaning them thoroughly with Adam's Tire & Rubber cleaner, then use Adam's Trim Restorer to get them back to "as new" color. Could top that off with Adam's Trim Coating to keep it black and protected as well.

The plastic is oxidized, you can use simichrome or other similar metal polish, or if you're brave or have done it before brake clean on a microfiber and a very quick wiping pass will remove it.

Oh Boy

Look no further as this is the best method I have found to do this. Buy this product and rub it in with the sponge applicator after you clean the area. I did this on my Grand Sport and they look brand new. And it is permanent.

This stuff works really well...

Be sure to clean the trim well first. I would use dawn followed by alcohol and maybe use a fine scotch bright pad on the surface that faces the tire.

I've used this for wheel wells to get them looking good. Depending on how much you drive in the rain, that will determine how long is lasts.
Looks great after you use it though.

I've asked this question before too.
Tried many techniques & products....for the inner liners.
Replacement is my option.

The flares/ rock guards, may restore with techniques outlined in this tread.
Good luck.

Griot's Garage Undercarriage Spray works well on things like this.

303 aerospace protectant works well on plastic

I'd try 303 first. If that doesn't work, heat gun. Or Wipe New, it's nasty stuff but it does work, surprising for something "As seen on TV."

I use the 303 Cleaner first then the Protectant. Makes mine look like new!!

I use 303 on all of my trim, inside and out..

Do a Google search for Carworx Refinish Restorer; the guys on Chevy Avalanche forums seem to love it, and those things are covered in vinyl cladding.

On my '05 my wheel liners where ugly and looked their age of 13 years. I cleaned mine with a stiff brush and sprayed then with a satin black spray paint for plastic (Fusion I think was the brand) They looked brand new and better than the new cracked piece I replaced.

OK here is your answer. The plastic cowl on my 1998 Camaro Z28 was faded very badly and was a light grey. I had previously used this product on the plastic shutters on my house with good results so I figured why not. I worked Perfectly, with 2 applications it has been black for 2 years now.
