What RetraxPro Tonneau Cover do I Need for my 2011 GMC Sierra with the 6' 6" Bed?


2011 GMC Sierra. Will the 6’6” retraxpro Mx cover fit the 5’8” bed I have.

There are a couple of great options for you but the RetraxPRO XR Hard Tonneau Cover w/ Trax Rails part # RTT-80373 was designed for certain model Ford F-150 trucks. Both of my recommendations will work with or without the factory cargo management system and offer very straight forward and easy installations using basic hand tools.

For your 2011 GMC Sierra with the 5' 8" bed the correct cover is the RetraxPRO XR Hard Tonneau Cover w/ Trax Rails part # RTT-80421. This offers the same aluminum construction and the trax rails like the other you were looking at. Retrax covers are extremely well built and hold up very well to the elements and usage.

The Trax rail system will allow you to add cross bars to the side rails of the cover helping you to further utilize your truck. A system like the Rhino-Rack Vortex Crossbar System part # RRVA180B for the cross bars and part # RRRLT600 for the matching leg kit. Which gives you two 71" crossbars that you can position anywhere along the tonneau rails. From there you can attach any roof mounted accessory or ladder rack accessory you might want.

The exact match to this cover but without the Trax rail system is the RetraxPRO MX Hard Tonneau Cover part # RT80421 this gives you the exact same features as the XR model you just loose the rails functionality.

Personally for such a minimal difference in the two I would choose the Trax system. You may not have a use for it now but very well may in the future.

I have linked the product pages for you and also the videos we have created on both the cover and the crossbar system I recommended.
