Norstar SM vs Norstar SD Flatbed: Which One Belongs on Your Truck?
Norstar builds some of the best flatbed truck beds available — and the SM and SD are their two most popular models. Both are quality American-made flatbeds. But they’re designed for different buyers. At Star Truck Equipment in Wharton, TX, we sell and install both. Here’s how to tell them apart and which to choose.
The Norstar SM Flatbed
The Norstar SM (Standard Model) is Norstar’s mid-tier flatbed — their most versatile and best-selling configuration. It’s a solid all-arounder that fits a huge range of applications:
- Steel construction — formed steel crossmembers and frame, good rigidity-to-weight ratio
- Available widths: 84″, 86″, 88″, 94″ to fit SRW and DRW trucks
- Available lengths: 7’4″–10’4″ (varies by truck CA measurement)
- Weight: approximately 650–900 lbs depending on configuration
- Standard features: rear bumper with receivers, stake pockets, LED lighting, D-rings, mud flaps
- Gooseneck provisions: integrated for 2-5/16″ ball and safety chains
- Finish: durable powder coat (black standard)
- Price: $4,000–$6,200 installed
The SM is the Norstar that gets put on ranchers’ Ram 3500s, contractors’ F-350s, and everything in between. It’s the flatbed that does it all without overspending.
The Norstar SD Flatbed
The Norstar SD (Super Duty) is Norstar’s heavy-duty commercial flatbed — built for buyers who need maximum strength and are running serious loads daily. Key upgrades over the SM:
- Heavier gauge steel — reinforced frame and crossmembers rated for demanding commercial use
- Wider available widths: up to 94″–102″ on DRW configurations
- Higher payload rating: designed for heavier commercial loads than the SM
- Heavier weight: approximately 800–1,100+ lbs depending on configuration
- Commercial-grade bumper: heavier rear bumper with reinforced receivers
- Enhanced gooseneck provisions: heavier-duty provisions vs SM
- Price: $5,200–$8,000+ installed

How to Choose: SM or SD?
Choose the Norstar SM when:
- You’re a rancher, farmer, or general contractor with mixed use
- Your loads are moderate — hay, fence supplies, tools, moderate equipment
- You want a quality flatbed at a reasonable price without heavy-duty premium
- Your truck is a SRW pickup (F-350 SRW, Ram 3500 SRW)
- You tow gooseneck trailers occasionally but it’s not your primary use
Choose the Norstar SD when:
- You’re in oilfield, pipeline, heavy construction, or fleet applications
- Your truck is a DRW dually — you need the wider deck to match fender width
- Heavy hauling is daily: pipe, steel, lumber, heavy pallets, machinery
- You’re running a cab-chassis (F-450, F-550, Ram 4500/5500) with serious payload
- You want maximum resale value from a proven commercial-duty flatbed
Also Consider: Norstar Service Bodies and Hay Beds
If you’re doing more compartmentalized service work than open hauling, check out the Norstar Service Body — it’s built on the same quality platform but with enclosed storage. For ranchers, the Norstar hay bed adds hydraulic bale handling capability.
