Product Description
Circle D | Special Deluxe (SD) Pickup Flatbed | Tapered Corners, 30K Gooseneck Ball, & Integrated Receiver Bumper
The Circle D Special Deluxe (SD) Pickup Flatbed takes the legendary durability of their standard platform and injects premium upgrades explicitly designed for heavy commercial towing. Manufactured by a veteran-owned company out of Hillsboro, KS since 1987, the SD flatbed is the ultimate choice for Treasure Valley farmers, ranchers, and hotshot drivers who require maximum trailer clearance and pre-engineered towing hardware right out of the gate.
We stock a wide variety of sizes and configurations to fit diverse vehicle applications. Every truck requires specific fitment parameters based on its generation, rear-wheel configuration, and cab-to-axle (CA) measurements. Popular footprints include:
Available Flatbed Sizes & Vehicle Fitment
Circle D cleanly splits their widths and lengths based on single vs. dual rear wheel chassis capacity to ensure perfect wheel-well flare clearance:
7' (84") W x 7' L: Engineered specifically for Single Rear Wheel (SRW) setups replacing factory short beds.
7' (84") W x 8.5' L: Standard 8-foot frame replacements for Single Rear Wheel (SRW) trucks.
8' (96") W x 8.5' L: Wide-deck configuration explicitly designed for Dual Rear Wheel (DRW) standard 1-ton swaps.
8' (96") W x 9.25' L: Extended length models built as a direct fit for commercial 60" Cab-to-Axle (CA) frames.
The SD Advantage: Purpose-Built for Towing
The Special Deluxe (SD) line is engineered to eliminate the friction of pivoting heavy trailers. By integrating tapered rear corners, this flatbed significantly improves chassis turning clearance when backing gooseneck trailers into tight job sites or barn doors. Furthermore, it completely eliminates the need for aftermarket hitch modifications by including an integrated rear bumper with a built-in receiver tube alongside a factory-installed 30,000 lb. gooseneck ball.
Special Deluxe (SD) Features
- The Structural Backbone: Heavy-gauge 4" x 2" rectangular tubing crossmembers on ultra-tight 12" centers, backed by 3" structural channel stringers and an HD steel tread plate platform.
- Enhanced LED Lighting: Rubber-mounted LED stop/tail/turn/backup lights in the rear skirt, plus an additional set of LED stop, turn, and tail lights embedded directly into the headache rack for maximum fleet visibility.
- Pre-Installed Towing: 30,000# gooseneck ball pre-installed and a rear bumper featuring a built-in receiver tube.
- Design Upgrades: Tapered rear corners for improved turning clearance, an integrated dedicated license plate bracket, stake pockets, and tie straps.
- Finish: Fully primed and painted high-gloss black to resist job site corrosion.
Optional Bed Upgrades
Upgrade and customize your Circle D SD flatbed to match your specific vocational needs. Popular point-of-sale add-ons include:
- Fold-Down Side Rails: An exclusive upgrade for the SD/SDT lines that instantly converts the open flatbed into a secure stake-body deck for loose cargo.
- Varying sizes of powder-coated or raw underbody toolboxes for secure storage.
- 18" x 24" black poly mud flaps for SRW trucks, or wider 24" x 30" poly mud flaps for DRW configurations.
⚠️ Critical Installation Requirements & Vehicle Sensors
Modern trucks feature highly complex safety and powertrain systems that directly impact the cost, requirements, and limitations of a flatbed upfit. We offer full in-house installation services Monday - Friday in our dedicated service bays. Please note the following common installation factors:
- Safety & Sensor Packages: Trucks equipped with factory backup cameras, parking proximity sensors, or cross-traffic Blind Spot Monitoring (BLIS) radars require specialized relocation kits, composite corner housings, or wire harness mapping. Metal flatbed side-skirts can block radar paths, meaning some sensors may need to be disabled or recalibrated.
- Powertrain (Gas vs. Diesel): Diesel platforms feature Diesel Exhaust Fluid (DEF) filler necks that require custom routing plates through the flatbed skirt or deck. High-heat exhaust paths during DPF regeneration cycles also require clear deflection tracking to prevent damage.
- Fuel Tank Configurations: Single mid-ship tanks versus factory dual tanks completely change the layout and positioning of fuel filler neck cutouts.
- Galvanic Corrosion Guards: For 2017+ Ford Super Duty trucks featuring aluminum cabs and frames, specific isolation brackets are required to prevent galvanic corrosion when mating to steel flatbed runners.
