78 Series UTE Tray — Maximum Deck Length for Mid‑Size Long‑Bed Trucks
The 78 Series aluminum tray system is engineered for mid‑size long‑bed trucks that need expanded deck length, increased storage capacity, and full underbody toolbox compatibility. This is not a universal flatbed. It’s a vehicle‑specific mounting system built around the geometry of long‑bed chassis, giving you a modular platform that installs cleanly, performs off‑road, and supports heavy daily use.
Why the 78 Series Exists
Long‑bed mid‑size trucks deserve a tray that actually uses the full chassis length without compromising departure angle or storage layout. The 78 Series delivers exactly that — a longer deck, more toolbox options, and a balanced footprint that works for overlanding, trades, and fleet use.
Engineered specifically for:
Double Cab Long Bed (DCLB)
Crew Cab Long Bed (CCLB)
Available widths: 72" (1828mm) and 76" (1930mm)
Available length: 6.5 ft (78")
The tray is designed to finish just past the end of the frame, maintaining a clean departure angle while maximizing usable surface area.
Base Pricing Includes
Your starting point is the SET Base Deck 72" (1828.8mm) wide × 78" long.
Required components included:
33" tire fenders
Fuel filler standard kit
Tailboard blank panel
Tray‑to‑frame mounting brackets
Plug‑and‑play supplemental wiring with LED DOT lighting, markers, reflectors, and plate light
Modular by Design — Build It Your Way
This is the part that sets SET trays apart. You don’t have to buy the entire system at once. Start with the base deck and add components over time:
20" or 26" rear underbody toolboxes
13" and 17" front underbody toolboxes
Water tank
4 ft rear drawer
Storage boxes
Side gates
Headboard
Footboard
Everything bolts on later. No cutting. No rewiring. No re‑engineering.
Your electrical stays plug‑and‑play. Your factory bed outlet can be relocated under the deck or inside an underbody box. Trailer plug, backup camera, sensors, blind‑spot modules — all have relocation brackets included.
Installation
Professional installation is recommended, but capable DIY owners can handle it with a helper or lifting equipment. Estimated install times:
New trucks: 8–10 hours
Older/salt‑exposed trucks: 10–15+ hours
If you ever need to return the truck to stock, the system is designed to make that possible.
Durability & Replacement Parts
Trail damage or accidents don’t total your tray. Every component is modular and replaceable — fenders, panels, brackets, under‑tray accessories, all of it.
Suspension Notes
Not mandatory, but recommended for mid‑size trucks depending on your build plan.
Base deck weights:
78 Series: ~255–275 lbs depending on configuration
Since factory beds weigh 250+ lbs, you’re often reducing weight before adding accessories.
Know your GVWR and plan your build accordingly.
Width Options
All mid‑size trays come standard at 72" (1830mm). 76" width is available by request.

Powder Coat Options
We offer powder coating, but recommend using your local coater for best results — especially for full trays being shipped. Smaller components can be coated in‑house. Color matching is attempted but not guaranteed to be 100% exact.
