The ZR2 truck is a truck that requires mudflaps if you travel gravel roads at all. Because of the widened stance of the vehicle and the rock-throwing tires that are typically installed, the rockers and flares can really take some abuse.

I do travel gravel roads quite a bit and it didn't take me very long after I purchased the truck to realize that some sort of rocker protection was going to be needed. Of course, I think the best solution is line-x'ing the rockers and flares but that's more $$ than I wanted to spend. So, I started looking for flares and found out that there is only one place where you can buy flares that will fit the ZR2 flare\wheel opening. This flap is pretty expensive (it is practically custom, after all) which turned me off right away, since I'm such a cheapskate. In addition, I did see some in person (someone offered my a used set for free) and I thought that I wanted a little more coverage than they would provide. I also noticed that they looked rather stiff and I wondered if they would break if you were wheelin' in sub-zero temperatures and knocked them on a log or rock.

Needless to say, I didn't go that route. I went to a few local auto parts stores and found these large, rubber flaps that are made for a full sized truck. They sure don't look as nice as other flaps I've see on ZR2's but they do provide good coverage, they were easy to install and definitely flex enough off road to not break anything.

If you do go with this type of mudflap, when you install it, make sure you offset the flaps to the outside at least 1". I offset mine a full 2" as you can see in the pic below to get full coverage for my mud tires. Also, on the front, if you have mud tires, you're likely to rub the flaps with the side knobs of the tire while turning.

I just used a few short, self-tapping screws on the flare side and some strong tie wraps to secure the other side to the fender support rod. You can't see it, but I used a 1" spacer on the attachment point at the bottom of the support rod to hold the flap "forward", otherwise it sorta "warped" and didn't look flat.

Here's a couple pics where you can see the overall look~

In this pic, I have the street tires on. No Rubbing problems because the tires are smaller, 255x70's.

In this last pic, notice I don't have the flaps on the front yet. The front tires have such little clearance that they rub while turning on the flaps. I raised the front up about 1" and re-installed the flaps and it still rubs if turning and hitting a bump at the same time. Very annoying. I may raise the front a bit more, I may not. I'm not taking the flaps off, I'm sure of that.
