I have to start by saying, if I never have to install these again, I'll be so happy. The installation was horrible. Making sure everything stayed lined up and having to use hand tools because power tools wouldn't fit with the tires in the way. Miserable! However, they look absolutely amazing and they are very secure. Very quality products for the Gatorback flaps. Seriously, these mounts are SOLID! I didn't even feel like I needed to tap em and say "that ain't going nowhere".
If you are used to installing aftermarket accessories, you know they never "line right up." I had redrill and move the tab bolt hole and use a carbide bit on 5 holes to line up with factory hole locations. Other than those 2 hiccups, which is normal and expected with aftermarket products (I build jeeps, toyotas, and trucks for a living) its a nice product. I used a kenworth semi mud flap and cut it down very pleased with fitment and how it looks. Glad its made out of aluminum too. WISH IT CAME WITH BLACK HARDWARE SO IT BLENDS IN!!!!
Very difficult to maintain alignment of brackets and rubber during final assembly. I have already submitted another review with a suggested solution to that problem.
I was not aware when ordering mud flaps that I needed the optional brackets. Cannot see installing them without the brackets - perhaps they should be part of the standard kit. Very nice quality.
