Are There Retractable Tie-Down Anchors for a 2008 GMC Sierra?

Helpful Expert Reply:

The ProGrip Retractable Tie-Down Anchors # 317-850760 are a confirmed fit in the factory stake pockets on the 2008 GMC Sierra, so as long as the chrome rail caps that you have on your bed rails have the same sized stake pockets as your factory rails these tie down anchors will work.

You may also want to have a look at the Bully Clamp Truck Bed Movable Tie Down # WTD-823. These are a moveable tie down that will work perfectly with your chrome rail caps since they mount under the side rails and provide you with an anchor point to secure cargo in your truck bed. With these, you won't need to worry about them not fitting your stake pockets and they will accomplish the same job.
