I cannot testify to road sport but the ones I have on my truck are husky liners I bought from JCwhitney.com. They work fine for me. The only problems I have with mine are that the splash guard goes up around the molding of my truck and with that, small rocks and dirt get stuck in there. Plus when I first installed them a long time ago it was a little hard to get into the areas to mount them with the tires on so if you can, take the tires off when mounting them. makes for a hell of a lot easier of a job. Finally, though this is probably my fault from the suspension, my rear mud flaps had scraped all the time when I went over bumps until I put z71 springs on the back. I don't know if this is because the mudflaps are designed for the XL version too or what the deal is. My truck was totally level when I first put them on and it would scrape but then again, having 1000 pounds of weight in the back of your truck all the time can help aid in bottoming out. lol. All in all though they are nice and tough, even when I got them scraped several times on the road. I just took a dremel to the scraped parts and got rid of the rough edges and you would never know they scraped. I like mine and the snow does not stick to them whatsoever. Hope this helps!
