The 12 Best Truck box extenders (2023 reviews)

The look and feel of this extenders are consistent with the high quality we're used to from the rest of Ecotric's lineup. It is extremely easy to assemble and install on your truck. Using a hitch tightener/stabilizer at the base of the T bar piece makes it feel a lot more solid. It supports lumbr, pipes or anything that hangs too far out of a standard truck bed. It is a little loose where connected by the easy release pins but it provides a stable platform once everything is properly tied down.

This hitch extender comes with reflective tape and flag on front and sides. The flag is a sturdy material that seems like it could easily handle a long interstate drive without issue, and comes with a metal clip at the top, to be securaly attached to whatever is hanging behind the rack. The adjustable width on the end makes it pretty convenient. It is easy to adjust to fit wider.
