Topline Truck Bed Extender Installation - 2008 Toyota Tundra

Today on our 2008 Toyota Tundra, we're going to review an install, the Top Line Bed Extender, part number BX4004-01. Here's what our bed extender look like once installed. What's really nice about the bed extender, especially on these short bed pickups is that it adds approximately 2 feet extension onto our pickup bed. Additionally, when it's not in use, it can simply be folded up as the clamps will secure the sides to the main body and then it folds down where the clamps will hold it to the brace. We can simply just close our tailgate and it's stored inside the pickup bed, or we have a situation where we need the entire length of our tailgate without the bed extender, we can pull the pin, which has a nice detent on it to keep it in place. We pull it out of the bracket on both sides and we completely remove our bed extender, opening our tailgate back up. Now, let's go ahead and show you how to install it. Now, to begin our install, we're going to open the tailgate.

Topline Truck Bed Extender Installation - 2010 GMC Sierra

Today on our 2010 GMC Sierra we'll be installing Topline fold down truck bed extender, part number BX4004-01. First note that this vehicle has a tailgate cover.

Now we'll go ahead and sit the bed extender up on the tailgate. We'll need to locate a flat surface for our SS brackets or stainless steel brackets to sit which will be our attachment points for the bed extender.

Bed Extender Questions and Answers

Will a Bed Extender Fit a Ford Explorer Sport Trac with a Bed Liner
The Topline Bed Extender, # BX4004-02, will fit if you have a bed liner. However, you may find that you will have to trim the bed liner on some vehicles.

On an Explorer Sport Trac, you will need to measure the width of the bed where the extender will fit. If it is 48 inches or greater in width, the extender will fit. We also have the Topline extender with an anodized...

How to Prevent Theft of the Topline Bed Extender # BX4004-02
What you would do to deter theft of the bed extender # BX4004-02 is to use security type of hardware. Something that requires an uncommon specialty tool to install/remove.

Will Topline Bed Extender BX4004-01 Fit on a 2007 Toyota Tundra with a Bedliner
You should not have a problem installing the # BX4004-01 bed extender on your 2007 Toyota Tundra, but you will probably need to trim away some of the bed liner in order to install the mounting brackets. The bed extender installs using two mounting brackets, one on each side of the tail gate. The bed liner trimming should be minimal, as these would basically be the only two points that would be obstructed. To get a visual of where you might need to trim, I recommend taking a look...

Bed Extender for 2011 Ford F-150 Compatible with UnderCover SwingCase Tool Boxes
Based on my review of photos of the UnderCover SwingCase tool boxes they will not be compatible with the X-Treme Gate Truck Bed Extender # XG-001. The extender when it is stowed takes up only 2-inches of space from the inside of the tailgate but the side brackets appear to use the same mounting points as the swing/hinge mechanism on the SwingCase boxes. Generally a manufacturer will not recommend installing two accessories that overlap at their installation points. A better option...
