2004 GMC Sierra 3500 Quarter Panels

I'm quite happy with these rear fender liners on my '06 2500 HD! They look and fit great, and really help keep the truck clean. They are plenty rugged to stand up to anything the tires can throw at them, and there's plenty of room for the upgraded 18x9 wheels with 275/65 tires. If you want rear fender liners on a new GM truck, they charge you $185 extra, so these are a great deal too. Plus these protect more of the frame and underside of the bed than the new-GM-truck liners. The only downside I found: the installation instructions didn't make clear which side each liner belongs on, so it took a bit of head scratching to get it right. Otherwise, installation was a breeze; I only had to drill 8 holes in each liner so I could put the existing push-pins back in the plastic fender lips and mud flaps. I'd buy these again in an instant!
