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 Fold Down Truck Bed Expander Review

Today we're going to review an install, the Top Line fold down truck bed extender, part number BX4004-02. Black in color. This application is also available in silver, part number BX4004-01. Let's go ahead and take a look at the top line tailgate extender that's all ready been installed. Simply open up the tailgate, we'll pick the extender up and swing the arm out and lock it in place. The arm is secured to the extender with the clamp, we pull it free, lift up on the spring-loaded button and it locks in to place. Just like that, our tailgate extender is up and secured. To get an idea, we'll go ahead and take a measurement from the end of the pickup bed to the inside edge here on the corner.

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. We'll need to remove the cover and locate the position for our bed extender. Let's go ahead and remove the fasteners and sit the cover aside. 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

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...

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. Since every vehicle and bed liner combination is different, I cannot say for certain if you will need to trim or not. 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...

Will a Topline Bed Extender Fit a 2013 Ford F-150 with Built-In Step in the Tailgate
The Topline bed extender # BX4004-02 is listed as a fit for the 2013 Ford F-150. However, it is possible that the bed extender could interfere with the use of the step in the tailgate. But the width is adjustable on the extender from 48 to 64 inches so you would be able to change the width slightly to avoid step interference. I have included a picture that shows an installed extender so you can see whereabouts it installs.
