Wheelbase:
Varies by cab and bed configuration (e.g., 140.5" for Regular Cab Long Bed, 160.5" for Crew Cab Long Bed).
Length:
Varies by configuration (e.g., 227.4" for Regular Cab Long Bed, 247.4" for Crew Cab Long Bed).
Width:
Approx. 79.9" (excluding mirrors)
Height:
Approx. 76.6" (varies by trim and 2WD/4WD)
Curb Weight:
Varies significantly by configuration, typically 6,000 - 7,000+ lbs
Gvwr:
Ranges from 9,000 lbs to 11,500 lbs for heavy-duty models.
Towing Capacity:
Up to 10,000+ lbs (properly equipped, depending on configuration and hitch type).
Payload Capacity:
Up to 5,000+ lbs (depending on configuration).
Oil Change:
Typically every 5,000 to 7,500 miles or 6 months for diesel engines, depending on operating conditions (severe vs. normal duty). Check manual for exact diesel oil change intervals.
Fuel Filter Replacement:
Recommended every 15,000 miles or annually for diesel fuel filters to prevent injector damage.
Air Filter Replacement:
Inspect every 15,000 miles, replace as needed or every 30,000 miles.
Engine Oil:
Cummins CES 20081 (API CJ-4 or equivalent diesel-specific oil), typically 15W-40 or 5W-40 synthetic depending on climate. Capacity: ~12 quarts.
Transmission Fluid:
ATF+4 for 48RE automatic; SAE 75W-90 synthetic gear oil for NV5600 manual; SAE 75W-90 for transfer case and differentials.
Coolant:
Cummins CES 14603 (or Fleetguard ES Compleat OAT coolant) or equivalent heavy-duty extended-life coolant, typically a 50/50 mix. Capacity: ~25-28 quarts.
Lift Pump Failures:
Early failure of the in-tank lift pump can cause fuel starvation and hard starting. Replacement with an upgraded aftermarket pump is common.
Injector Problems:
Common rail injectors can be sensitive to fuel contamination; regular fuel filter changes are critical. Symptoms include rough running, misfires, and black smoke.
Overhead Cam Shaft Wear:
While robust, some high-mileage engines may exhibit wear on the camshaft lobes. Proper lubrication is key.
Transmission Hard Shifting:
Automatic transmissions (48RE) can develop hard shifting or torque converter issues. Manual transmissions (NV5600) are generally robust but clutch wear is normal.
Exhaust Gas Recirculation:
EGR valve clogging or failure can lead to performance issues and check engine lights, though some 2006 models may have had fewer emissions controls than later years.
