NOTE:
Bed lengths vary by year, make and model
of vehicle. The dimensions provided above
are for example only, not intended for part-
specific fitments.
MEASURING BED LENGTH
All the products we sell are custom-
made to fit your truck. Bed length is
often a key indicator for compatibility.
TO DETERMINE BED LENGTH,
measure from the inside of the
tailgate to the inside of the bulkhead
(see image).
NOMENCLATURE GUIDE
Vehicle manufacturers refer to their cab styles and bed lengths in multiple ways, adding complexity when
identifying compatible products. This guide was created to help you compare how each brand describes
these vehicle components to their Automotive Aftermarket Industry Association (AAIA) standardized name,
making it easy to find a compatible part for your vehicle.
