2. What Is the 2009 Chevrolet C6500 Box Truck 13’6?

The 2009 Chevrolet C6500 is part of GM’s C-Series Kodiak/TopKick medium-duty lineup (Class 6–7 range). The “13’6”” in the model name refers to a factory or common aftermarket cargo box length of 13 feet 6 inches — a sweet spot for urban and short-regional routes that need substantial volume without the complexity of larger Class 8 rigs. The Kodiak/TopKick series offered multiple cab and chassis configurations tailored for box trucks, roll-backs, refrigerated vans, and specialty conversions.

3. Key Specifications of the 2009 Chevrolet C6500

Engine options (common):

• 6.6L Duramax LMM V8 diesel — widely used in Kodiak/TopKick applications, popular for cleaner emissions and strong mid-range torque. Output commonly quoted around ~260–300 hp depending on tune and application.
• 7.8L Duramax (LG4/LF8) inline-6 diesel — higher displacement inline-6 used in heavier duty spec packages with torque ratings that can reach up to 860 lb-ft in certain tune levels; output ranges historically from ~195–300 hp depending on calibration.

Transmission:

• Allison automatic transmissions (2000/2400 series or similar heavy-duty Allison automatics) are commonly fitted for smooth, reliable shifting under load.

GVWR / Class:

• Typical Gross Vehicle Weight Rating (GVWR) ranges for C6500 configurations run between 19,500–25,950 lbs (Class 6). Some brochures and chassis specs list GVWR options starting around 22,000 lbs depending on upfit and configuration. Always verify the VIN/door placard for the exact GVWR on any unit.

Cargo box dimensions (typical for 13’6 box):

• Length: 13 ft 6 in (interior)
• Width (approx): 8.0–8.5 ft
• Interior height (typical): 6.5–8 ft depending on box spec and roof options

Chassis & body: rear-wheel drive, heavy-duty frame rails designed to accept a wide range of bodies (aluminum, fiberglass-reinforced panels, or steel), with hardwood floor as common factory or aftermarket option.

Fuel type: Diesel (Duramax variants)

Typical payload: Depending on GVWR, box construction, and curb weight, useful payloads commonly exceed 8,000–14,000 lbs, but exact payload depends on your truck’s configuration and conversions — check the vehicle placard to calculate real payload.

4. Performance and Drivability

Horsepower & Torque

The C6500’s available diesel options make it a workhorse for city deliveries and regional hauls. The 6.6L Duramax typically delivers strong horsepower in the ~260–300 hp range with torque in the ~520 lb-ft neighborhood in pickup/truck calibrations used in Kodiak applications, while the 7.8L inline-6 provides more torque at lower RPMs — valuable when hauling heavy payloads or towing. Exact outputs vary by engine tune and whether the unit has emissions-related equipment fitted.

Transmission & drivability

Paired with Allison automatics, the C6500 is easy to drive for operators with limited medium-duty experience. The Allison transmissions are engineered for stop-and-go urban work as well as highway runs, and they tend to reduce driver fatigue compared with manual gearboxes. Expect predictable gearing for loaded starts and good engine braking capability in moderate grades.

Fuel economy

Medium-duty diesel fuel economy varies widely with load, route profile, and driving style. Expect 7–11 mpg as a realistic range in mixed urban/regional use for a 2009 C6500 with typical box configuration — heavier loads and stop-start routes will push the number toward the lower end. These figures align with real-world reports for similar Kodiak/TopKick chassis from the era.

5. Cargo Space and Build Quality

Box construction & materials

The 13’6 box is commonly built from aluminum panels (for corrosion resistance) or fiberglass-reinforced panels, and many fleets specify hardwood plank flooring for durability under heavy loads. The box simplicity makes it easy to outfit with shelving, e-track tie-downs, and custom racking for trade-specific work.

Rear access & options

Common options include roll-up doors, barn doors, or liftgates (electric/hydraulic) depending on the customer’s needs. Interior LED lighting and tie-downs are typical aftermarket additions for safety and cargo security. These modifications make loading/unloading safer and faster for moving companies and delivery fleets.

8. Challenges and Things to Consider

Fuel economy vs. modern trucks

While diesel durability is excellent, fuel economy won’t match modern medium-duty models that use advanced engine management, aerodynamics, or hybridization. Expect lower mpg compared with the newest Class 6/7 trucks.

Emissions and compliance

Depending on your state or municipality, emissions equipment and retrofits may be required, and some clean-air zones restrict older diesels. Check local regulations — you may need DPF, upgraded emissions systems, or aftermarket solutions to meet current standards.

CDL & operator considerations

If the configured GVWR pushes beyond local thresholds (often 26,000 lbs in the U.S. for CDL triggers, but check local rules), you may need drivers with a commercial driver’s license. Verify the truck’s placard and local laws before you schedule routes.

9. Maintenance and Common Issues

Common wear points

• Turbocharger wear (especially in high-mileage diesel engines) — check for shaft play and oil contamination.
• Transmission service needs — Allison automatics are durable but require fluid and filter changes at recommended intervals.
• Brake system wear — heavier loads require frequent brake inspections, especially if the truck uses hydraulic brakes rather than air.
• Suspension bushings and spring fatigue on high-cycle trucks.

Preventive maintenance checklist

• Oil & filter changes every 5,000–10,000 miles depending on duty cycle and oil type.
• Transmission fluid and filter every 30,000–60,000 miles (follow Allison recommendations).
• Inspect brake pads/drums & lines monthly for heavy use.
• Fuel filter replacement every 20,000 miles or per service schedule.
