Do not know. I have mine installed on a 2011 Pilot. There are good quality running boards with easy installation.

i bought these for my extended cab, 2007 f150. go back on line and put it in for a crew cab. ( 4 door) i believe they will be a little longer.

i cannot 100% say it will but it fits just fine on a 2009 Gmc Sierra crew cab. I would think the bed diameter is not that much different if at all.

They should fit just fine. My son put them on his 2002 GMC 1500 and they were fine.

I bought them for 2013 Silverado 1500 crew cab. They were easy to put on. Given the wheel wells and fender size are shared so I believe they do.

Should fit well. I installed on my 2005 extended cab 5.3 last year. Worth every penny.

They fit just fine on my quad cab. They might be a short for the extended cab.

There is an app. in amazon that will ask if they fit. Go into the Search and just do auto. It will tell you if they fit. But My Truck is a 06 Dodge short bed extended cab and they fit mine. Good luck

I used them on my 2008 Sierra Denali 1500 and it melted and warped the mud flap. I'm guessing the same thing will happen with your truck. Good luck.

Mine were for a 2005 ranger xlt extended cab. They fit perfectly. One for each side. They have a configurator to verify

It should fit A Sierra as long is the same year, just look at it carefully and see if the mounts are the same as our vehicle that is what I did before I ordered them

I believe you order them by make and model. Example: GMC Sierra 1500 regular cab or extended cab or crew cab. On my regular cab they fit on the frame just behind the front mud flap and extend to the frame bracket near the rear of the cab. Hope this helps.

My husband installed them on a 2012 z71 extended cab and they fit nicely. Hope this helps.

I am pretty sure they will fit. I own a 2013 GMC Sierra and they fit, and i believe the 2010 Chevy and 2013 GMC are the same body style.

My dad has a 2014 GMC Sierra, the covers were a bit snug but they did fit. Not sure how big the head rest are in the type of truck.

They should, my truck was extended cab with a factory lay in bedliner and it fitted perfect.
