Hey guys, just go a membership on this site after I picked up my new/used ride. It's not a Topkick or Kodiak but it is a commercial truck.
First question I have is I would like to find a little wider fender flare for my truck. With the DWR setup, solid front axle, I notice that my tires stick out about 1.5 to 2 inches past the flares. It's not much, but it's annoying to me when I go through some mud and it slings up onto the hood. That and I'm shooting mud and debris forward onto the front bumper.
You should be able to get fender flares for these, I'm sure it's probably an option. You might want to try the guys at www.yourworktruck.club (a partner to this site) and see what they have to offer you.
You can only put them on the front but try Bushwacker.com or 4wheelparts.com
Like you were looking for before, the rubber inserts that just get matched up with the push pins on your previous fender flares. They're like $20, and they're just two rubber pieces around 3-4" wide, and give you that extra protection.
