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).
