Choosing the right truck bed starts with understanding the dimensions. Whether you’re upgrading a Ford F-350, Ram 3500, or Chevy Silverado, the 903 Truck Beds lineup offers three core models: SD (Skirted Flat Deck), FD (Flat Deck Non-Skirted), and CD (Cabinet Deck). Each model comes in multiple sizes to match short bed, long bed, single rear wheel (SRW), or dually trucks.
This guide breaks down the exact measurements for each model. You’ll find width, length, cab-to-axle (CTA) specs, and fitment tips to ensure perfect compatibility.

903 Truck Beds uses two main widths to fit most modern trucks:
