How-To Measure Your Truck
The following instructions generally work well when measuring a full-size truck. Mid-size and Compact trucks have a variety of
truck bed configurations which increase the difficulty in measuring the truck and comparing it to the dimensions of a specific
truck box. In nearly all instances, the Fitment Guide (pages 54 through 59) will provide accurate information unless the truck is a
new model introduced after August, 2013.
THE TRUCK BED NEEDS TO BE MEASURED FOR TWO REASONS:
A. To Determine that the Truck Box will be long enough to be properly mounted on the truck bed rails.
B. To Determine whether or not the truck wheel wells will interfere and prevent proper mounting of the truck box.
A: DETERMINING THAT THE TRUCK BOX IS LONG ENOUGH TO BE PROPERLY MOUNTED:
MEASUREMENT 1: Width between the top of the bed sidewalls....Dimension “ A” of the crossover Truckbox needs to be at least
3” greater.
B. DETERMINING WHETHER OR NOT THE TRUCK BOX WILL CLEAR THE WHEEL WELLS IN THE TRUCK....NEED TO FIND
POINT “X” IN THE TRUCK BED:
Preparing to take Measurements 2 & 3 to find a point “X” in the truck bed to ensure that the truck box will fit your truck:
• The depth of the truck box may restrict its fit in the truck because the wheel well might be in the way.
• Except for “Extra-Wide” truck boxes, most truck boxes will require 20 1⁄4” of horizontal space from the cab bed rail to the
point where the Truck Box might hit the wheel well or the truck bed liner .
MEASUREMENT 2: A “Standard” Truck box will usually have a 9” V ertical depth below the top of the truck bed rail. A “Deep ” model
will usually be 12” below the top of the bed rail.
• Determine how deep a truck box you need and measure down from the top of the rail and create an imaginary,
HORIZONTAL line at the depth of the truck box you need...usually 9” or 12” below the top of the truck bed rail. This is called
Dimension “C” on the truck box.
MEASUREMENT 3: Find Point “X” which is on the horizontal “Imaginary Line ” below the truck rail (from “2” above). On the horizon-
tal “Imaginary Line”....Measure to find a point 20 1⁄4” away from the front truck bed rail (This measurement is from the Cab Truck
Bed Rail Towards the Tailgate). The 20 1⁄4” is roughly Dimension “E” on the truck box and represents how much space the truck
box will take in the bed behind the truck cab. After finding Point “X” in your Truck Bed....will the truck box fit?: Again, Point “X” is
20 1⁄4” away from the front truck cab rail on the Imaginary Horizontal Line (from measurement 2) If point “X” does not hit the
wheel well, the truck box will fit. If point “X” hits the Wheel Well, you must make another measurement:
• Mark Point “X” on both wheel wells or the wheel well bed liner
• Measure the distance between the two point “X”s on the truck bed. This dimension must be greater than Dimension “B”
on the Truckbox
• If Dimension “B” on the truck box is GREATER
than the distance between both point “X”s,
the truck box will hit the wheel well or bed
liner and you will usually need to select
another truck box or mount the truck box
with a spacer above the bed rail.
