A.R.E. Diamond Edition Deluxe Commercial Unit
The commercial DCU wrapped in polished diamond-plate aluminum.
Truck CapDiamond Edition takes the commercial DCU and skins it in .063-inch diamond plate aluminum polished to a mirror finish, over the same .050-inch TIG-welded frame. It is the toughest-looking cap A.R.E. builds and the surface hides scuffs the way a toolbox lid does. Full-width rear doors ride on stainless steel strap hinges.

The line beside it
Where these 3 actually differ:
| Specification | A.R.E. DCU | A.R.E. Diamond Edition DCU | A.R.E. DCU MAX |
|---|---|---|---|
| Body | .035in aluminum skin on a welded frame | .063in diamond plate on a welded frame | .063in aluminum skin on a welded frame |
| Finish | Baked enamel: white, black or silver | Polished diamond plate | Baked enamel white as standard |
The same on every one of them
It is the top of the three commercial aluminum caps, and the difference is entirely the skin. DCU is .035-inch smooth. DCU MAX is .063-inch smooth. Diamond Edition is .063-inch diamond plate, polished. Same frame, same doors, same 3-year warranty on all three. You are choosing thickness first and appearance second.
Trades who want the truck to look the part on a customer's driveway, and anyone already running diamond plate boxes or a headache rack who wants the cap to match.
