2025 Ram 4500 Truck Body Options — Flatbeds, Service Bodies & More

The 2025 Ram 4500 is one of the most popular medium-duty chassis cab trucks in Texas. With a max payload over 9,000 lbs, a robust frame rail, and multiple cab-to-axle configurations, the Ram 4500 is purpose-built to carry serious commercial truck bodies. At Star Truck Equipment in Wharton, TX, we carry flatbeds, service bodies, crane bodies, hay beds, and more — all designed to fit the 2025 Ram 4500.

2025 Ram 4500 Cab-to-Axle (CA) Measurements

The Ram 4500 is available in Regular Cab, Crew Cab, and Mega Cab configurations, each with different CA measurements. CA (cab-to-axle) is the distance from the back of the cab to the center of the rear axle — it determines the maximum body length you can fit.

  • Regular Cab 4×2 / 4×4 — CA 84″ or 96″
  • Crew Cab 4×2 / 4×4 — CA 60″ or 84″
  • Cab & Chassis (no bed) — Standard configuration for truck body installation

As a general rule, body length = CA + 12″ to 18″. A 60″ CA supports a 7–8 ft body; an 84″ CA supports a 9–10 ft body; a 96″ CA supports a 10–11 ft body.

Ram 4500 vs Ram 3500 — Why Go Medium Duty?

The Ram 4500 steps up from the 3500 with a higher GVWR (up to 16,500 lbs vs 14,000 lbs for the 3500). This extra capacity is critical when you’re adding a heavy service body, crane body, or a fully loaded crane — the 4500 gives you room to grow your payload budget. If you’re outfitting a serious work truck — welding rig, lube truck, or crane truck — the 4500 is often the smarter choice.

Service Bodies for the 2025 Ram 4500

The Ram 4500’s higher GVWR makes it an ideal base for a service body. Electricians, HVAC technicians, plumbers, and oilfield service companies all rely on the Ram 4500 platform for their utility trucks.

  • CM Service Bodies — CM offers aluminum and steel service bodies with lockable compartments and rugged all-weather durability.
  • Norstar Service Bodies — Deep compartment service bodies with smooth aluminum doors. Clean look and plenty of storage for tools and equipment.
  • RKI Service Bodies — RKI’s modular service bodies are popular with contractors who need flexible compartment layouts.
  • NXG Service Bodies — Innovative designs with integrated lighting and weatherproof construction. Good choice for telecom and utility fleets.

Crane Bodies for the Ram 4500

The Ram 4500 is a popular base for crane body configurations. The higher GVWR gives you the payload budget for both the crane body weight and a Tiger or AutoCrane truck-mounted crane.

  • STI Crane Bodies — STI builds rugged crane bodies purpose-designed for medium-duty chassis. Integrated crane mounting provisions, outrigger pockets, and hydraulic oil tank provisions.
  • RKI Crane/Lube Bodies — RKI offers crane and lube body configurations compatible with the Ram 4500 frame.

Hay Beds for the Ram 4500

Texas ranchers who need to move large volumes of round bales often prefer the Ram 4500 over a 3500 for its extra payload. A hay bed on a Ram 4500 gives you the capacity to haul multiple 1,000+ lb round bales safely.

  • CM Hay Beds — Available in steel with spike or roller options. Designed specifically for round bale handling.
  • Bedrock Hay Beds — Powder-coat finish with heavy-duty bale spikes and rugged steel construction.

Ram 4500 SRW vs DRW — Which Is Right for Your Body?

The Ram 4500 is available in both single rear wheel (SRW) and dual rear wheel (DRW) configurations. For most commercial truck bodies over 9 feet, DRW is recommended — it provides a wider stance, better stability under load, and is required for some body certifications. SRW configurations are fine for lighter applications and are easier to maneuver in tight job sites.
