Frequently Asked Questions

Find answers to common questions about torque specifications

Q1

What are the main differences between the available engine options?

The 2008-2015 Ram 4500 offers two primary engine options: a 5.7L HEMI V8 producing 383 hp and 400 lb-ft of torque, and a 6.7L Cummins Turbo Diesel I6 generating 350 hp and 650 lb-ft of torque. The HEMI V8 provides smooth acceleration and is ideal for lighter loads, while the Cummins diesel excels in heavy-duty towing and hauling with superior torque and fuel efficiency.

Q2

What transmission options are available?

The Ram 4500 comes with two transmission options: a 6-speed automatic (68RFE) paired with the Cummins diesel engine and a 5-speed automatic (545RFE) for the HEMI V8. Both transmissions are designed for durability and smooth shifting, with the 68RFE featuring enhanced torque capacity for heavy-duty applications.

Q3

What are the key safety features?

Standard safety features include anti-lock brakes (ABS), electronic stability control (ESC), and dual front airbags. Optional features include a backup camera, trailer sway control, and hill-start assist. Advanced safety systems like adaptive cruise control and blind-spot monitoring are available on higher trims.

Q4

How does the fuel economy compare to competitors?

The Ram 4500 with the Cummins diesel engine achieves an EPA-estimated 14 mpg city and 20 mpg highway, while the HEMI V8 offers 12 mpg city and 17 mpg highway. These figures are competitive with similar heavy-duty trucks like the Ford F-450 and Chevrolet Silverado 4500HD.

Q5

What are the recommended maintenance intervals?

Recommended maintenance includes oil changes every 7,500 miles for the HEMI V8 and every 15,000 miles for the Cummins diesel. Inspect brakes, tires, and fluids every 10,000 miles, and replace the fuel filter every 30,000 miles for diesel models.

Q6

What are the most notable features and options?

Standard features include air conditioning, power windows, and a 6-speaker audio system. Optional upgrades include a premium sound system, heated seats, a touchscreen infotainment system with navigation, and a power sunroof. Higher trims offer leather upholstery and advanced towing packages.

Q7

How does the cargo and passenger space compare to competitors?

The Ram 4500 offers a spacious cabin with seating for up to six passengers. Cargo bed dimensions are 8 feet long, 6.5 feet wide, and 1.5 feet deep. Interior dimensions are comparable to the Ford F-450 and Chevrolet Silverado 4500HD, with slightly more legroom in the rear seats.

Q8

What are the towing and payload capacities?

The Ram 4500 boasts a maximum towing capacity of 17,990 lbs when properly equipped. Payload capacity ranges from 5,990 to 7,390 lbs depending on the configuration. These capacities make it one of the most capable heavy-duty trucks in its class.
