Outlet Polished DiamondBack SE - fits Next Generation ’19-up GMC Sierra 1500 Long Box


Why is this unit in the DiamondBack Outlet?

This DiamondBack SE was an R&D cover made 1/4" too long and wide at the tail. As a result, the appearance may be off but also potential leaking. 

All DiamondBack Outlet items are run by the same quality checklist as regular DiamondBack items and carry the same lifetime warranty.
