Ram trucks — from the Ram 2500 Power Wagon to the Ram 5500 chassis cab — are among the most popular work truck platforms in Texas and Louisiana. And CM Truck Beds (Madill, Oklahoma) is one of the best-matched brands for Ram’s full lineup. Here’s how CM beds fit Ram trucks, which models work best, and what you can expect to pay.
CM Truck Beds: Why They Work Well with Ram
CM Truck Beds are engineered with specific cab-to-axle (CA) measurements that align with Ram’s range of chassis configurations. Ram’s DRW (dual rear wheel) and SRW (single rear wheel) options, combined with various CA lengths, make it one of the most flexible platforms for work truck upfitting — and CM’s broad model lineup takes full advantage of that flexibility.

Ram Cab-to-Axle Guide for CM Beds
Choosing the right CM bed starts with knowing your Ram’s cab-to-axle measurement. Here are the common CA lengths for Ram work trucks:
- Ram 2500 Regular Cab: ~60″ CA — fits 6’–7′ CM flatbeds or hay beds
- Ram 2500/3500 Crew Cab SRW: ~56″–60″ CA — tight fit; typically 7’–8′ bed
- Ram 3500 DRW Crew Cab: ~60″ CA — CM RD/SK/RS on 8’–9′ bed
- Ram 4500 Chassis Cab: 60″, 84″, or 108″ CA options — CM ER/SBF range
- Ram 5500 Chassis Cab: 60″, 84″, 108″, or 132″ CA — full commercial CM lineup
At Star Truck Equipment in Wharton, TX, we measure your specific Ram before ordering — factory CA can vary slightly by build date and option package. Getting the exact CA prevents overhang issues and ensures proper gooseneck alignment if you’re towing.
Ram SRW vs DRW: Which CM Bed Fits?
Single rear wheel (SRW) Rams (3500 SRW and 2500) are best paired with CM’s lighter-duty flatbeds — the RD, RS, or Warrior aluminum. Bed widths in the 82″–86″ range fit SRW fenders cleanly.
Dual rear wheel (DRW) Rams open up the full CM lineup, including the wider SK, ER, and heavy commercial flatbeds. DRW fender-to-fender width accommodates 86″–96″ CM bed widths without modification. If you’re planning gooseneck towing regularly, DRW is strongly preferred.
