The 2025 Chevrolet Silverado 3500HD in dually (DRW) configuration is one of the most capable work trucks on the market. With dual rear wheels spreading the load across a wider stance, the 3500HD DRW is purpose-built for heavy flatbeds, service bodies, and equipment hauling. But choosing the right truck bed for your Silverado dually is a decision that can make or break how well your rig performs on the job.
At Star Truck Equipment in Wharton, TX, we upfit Chevy Silverado 3500HD duallies every week for contractors, ranchers, oilfield crews, and ag operators across Texas and Louisiana. Here’s everything you need to know about picking the right flatbed for your 3500HD DRW.
Why Go DRW on the Silverado 3500HD?
The dual rear wheel setup on the 3500HD gives you several advantages when you’re running a flatbed:
- Higher payload capacity — DRW models typically carry 500–1,000 lbs more than their SRW counterparts
- Better stability under load — Wider rear stance reduces sway when hauling heavy equipment or livestock
- Gooseneck-ready — DRW trucks are the preferred platform for 5th wheel and gooseneck hitches
- Flatbed compatibility — Most commercial flatbed crossmembers are engineered for DRW cab-to-axle measurements
The 2025 Silverado 3500HD DRW with the Duramax 6.6L diesel puts down up to 470 hp and 975 lb-ft of torque — more than enough grunt to handle whatever flatbed configuration you run.
Cab-to-Axle (CA) Measurements for the 2025 Silverado 3500HD
Before ordering a flatbed, you need to know your cab-to-axle (CA) measurement. On the 2025 Silverado 3500HD crew cab DRW, the CA typically runs around 56–60 inches depending on configuration. Regular cab and double cab versions have longer CAs, which open up larger flatbed options.
A general rule: add 60 inches to your CA measurement for the total flatbed length. A 60″ CA gives you roughly an 8’6″ to 9′ flatbed — the most common size for a Silverado 3500HD DRW.
Best Flatbed Brands for the 2025 Chevy Silverado 3500HD DRW
CM Truck Beds — The Workhorse Standard
The CM RD flatbed is one of the most popular fits for the Silverado 3500HD DRW. Built from high-strength steel with a powder-coat finish, CM flatbeds are known for their clean welds, toolbox integration, and compatibility with gooseneck hitches. The CM SK is a skirted option for buyers who want a finished look without sacrificing payload. CM also offers the Warrior series for heavier-duty applications — a favorite among South Texas oilfield and ranch operators.
Norstar Truck Beds — Rugged Texas-Proven Steel
The Norstar SD flatbed is a Texas ranch and oilfield staple. Heavier-gauge steel than many competitors, the Norstar SD handles abuse on rough county roads, lease roads, and job sites without complaint. If you’re running your 3500HD dually through brush or hauling heavy oilfield equipment across South Texas, the Norstar SD is a serious option. Available in 8′, 8’6″, and 9′ lengths to fit most 3500HD DRW CA measurements.
Bedrock Granite 9G — Premium Steel Performance
The Bedrock Granite 9G is built from 9-gauge steel with a lifetime structural warranty. It’s one of the heaviest-duty flatbeds we carry — built for contractors and haulers who need a bed that won’t flex or crack under daily heavy loads. The Granite 9G’s formed one-piece floor and fully boxed frame rail make it one of the stiffest flatbeds you can put on a 3500HD DRW platform. See our full Bedrock Granite 9G review for a deep dive.
Pronghorn Flatbeds — Value-Focused Build
The Pronghorn flatbed offers solid construction at a price point that makes sense for buyers outfitting a fleet or working within a tighter budget. Available in steel configurations, Pronghorn flatbeds fit standard 3500HD DRW CA measurements and come with toolbox pockets and stake pockets as standard features — making them a practical choice for ranchers and small contractors.
Flatbed Configurations for the Silverado 3500HD DRW
When choosing a flatbed for your 3500HD dually, you’ll decide between several key configurations:
- Flat deck (open flatbed) — Maximizes loadable surface; most popular for ranchers and construction crews
- Skirted flatbed — Cleaner look, hides frame rails; popular on farm and ag operations
- Flatbed with headache rack — Protects cab glass; recommended if you’re hauling pipe, lumber, or rebar regularly
- Flatbed with underbody toolboxes — Trade-focused; keeps tools and equipment organized and accessible
Gooseneck Hitch Integration on a Silverado DRW
One of the biggest reasons Silverado 3500HD DRW owners opt for a flatbed is gooseneck towing capability. All of our flatbeds can be ordered with or installed with a B&W Turnoverball or compatible gooseneck hitch in the bed floor. With the 3500HD’s gooseneck towing capacity (up to 36,000 lbs with the Duramax diesel), you want a flatbed with proper crossmember gooseneck cutouts and reinforced frame mounting — something all of our brands handle correctly.
When we install a flatbed at Star Truck Equipment, we ensure the gooseneck hitch is properly positioned relative to the rear axle centerline — typically 2 inches forward of the axle center for proper tongue weight distribution.
DRW vs SRW: Does It Affect Flatbed Selection?
Yes — DRW trucks have wider rear fenders and mudflaps, which means your flatbed mounting must accommodate the dual wheel flares. Most commercial flatbeds are built with DRW fitment in mind, but the mounting approach differs from SRW trucks. If you’re comparing your options on a single rear wheel 3500HD, see our separate guide on the best truck beds for the Chevy Silverado 3500HD (SRW).
What Does It Cost to Put a Flatbed on a 3500HD DRW?
A quality steel flatbed installed on a 2025 Chevy Silverado 3500HD DRW typically runs $3,500–$7,500 installed depending on brand, size, and accessories. CM and Pronghorn tend to be on the lower end; Bedrock and Norstar with headache racks and underbody toolboxes can push toward the higher end. All prices include professional installation at our Wharton, TX shop. For a deeper breakdown, read our guide on how much a flatbed truck bed costs.
