Truck Hardware has not licensed the LTZ logo for the flaps. All logos available can be seen here, https://www.sharptruck.com/truck-hardware-gatorback-chevy-logo-mud-flaps
As of 1-29-2018 Truck Hardware is working on a no drill custom fit get for the ZR2. They are done with the first test fit and are working hard to have them done. I can add you to the preorder list and will send out updates as I get them
If you have oversized tires on the truck as well i would recommend these, https://www.sharptruck.com/gatorback-chevy-lifted-truck-mud-flaps
If your tires do not stick out passed the wheel well, you can use the 12" wide flaps and mount them with the universal offset brackets. which you can find here, https://www.sharptruck.com/truck-hardware-universal-mud-flap-brackets. Both the 1" or 1.5" offset will work for what you need.
Replacement plates can be purchased here, https://www.sharptruck.com/truck-hardware-gatorback-chevy-gmc-replacement-plate
The rubber is covered by a lifetime warranty. If you need a rubber flap send a picture of the damaged flap to [email protected] and we can help from there.
If a person has tried that i am not aware of it. You would more than likely run into clearance issues between the flap and tire is you install it that way.
The Gatorback flaps will work on a truck with OEM fender flares. Enter in your trucks information in the fitment selector and there is a question about the flares. The site will show you the options based on your selections
Yes, there are two options.
These install overtop of the existing mud guards - https://www.sharptruck.com/search?q=gcr202k
These come with finishing caps that replace the factory guards - https://www.sharptruck.com/search?q=gcr203k
They flaps will work. If you have access to fasteners in the lip of fender you will not have to drill through. If there are not fasteners, you will have to drill through the flares.
Here are all of the custom fit options from Gatorback. https://www.sharptruck.com/search?q=GCR55K
If you would like something that is outside the wheel well a little you can do these offset brackets and flaps. There is an install video on the brackets.
