"The bed rail protectors are professional quality and were easy to install. Shipping was extremely fast too." —John J from Tifton, GA bought a Bushwacker Ultimate OE Style BedRail Caps for a 2011 GMC Sierra, 5' 8" short bed.

"the oval flat black plastic separators did not fit flush with the top of the bed rail as there is a protector on top of the side that is a continuation of the bed insert and it is rectangular. therefore the ovals had to be filed down to fit into the rectangular openings. other than that installation was easy" —Richard D from Ocean City, NJ bought a Putco Locker Side Bed Rails for a 2011 GMC Sierra, Short bed (approx. 5' 9").

"I got these for my Extended Cab Sierra 1500, great fit, easy install. Had to trim a little around the tailgate area for clearance but was very easy. Very impressed with the product especially considering the price. They look great and match the stock tailgate cover pretty well." —Kathryn A from Arvada, CO bought a Bushwacker Ultimate OE Style BedRail Caps for a 2011 GMC Sierra, 6' 6" short bed.

They matched the tailgate protector perfectly and I had them installed within fifteen minutes of receiving them from the UPS man....good product." —Jerome B from Doniphan, MO bought a Bushwacker Ultimate OE Style BedRail Caps for a 2011 GMC Sierra, 5' 8" short bed.

"I got the oem style that matches the tailgate protector and it looks great. I dont know if they will stay on or not for the duration yet as some parts of the adhesive wont stay tacked to the trucks rails, they keep lifting up. There are additional clips and screws to hold them, and so far after a few weeks, they haven't moved or come apart. Overall happy so far." —Scot A from East Berne, NY bought a Bushwacker Ultimate OE Style BedRail Caps for a 2011 GMC Sierra, 6' 6" short bed.

"VERY NICE FINISH. FIT VERY WELL. JUST MAKE SURE TEMPERATURE IS WARM SO THE TAPE STICKS. PUT SOME WEIGHT ON TOP OF THEM TO PUT PRESSURE ON THE TAPE TO STICK BETTER. LOOKS REALLY GOOD ON THE TRUCK." —John A H from Little Falls, NY bought a Bushwacker Ultimate SmoothBack BedRail Caps for a 2011 GMC Sierra.

"The installation took me 35-40 minutes on my 2011 Sierra. Would have been less, except I put some rust inhibitor paint on the 4 required drilled holes in the inside rail of the bed, and waited for the paint to set. I have seen comparable products with lesser materials for much more money. This is a great buy, you will be satisfied. I have bought many products from them and Auto Anything has the most reliable and quick delivery I have ever seen." —Robert A V from Safford, AZ bought a Dee Zee Brite-Tread Side Bed Caps for a 2011 GMC Sierra, 6' 6" short bed.
