Owning a 2026 RAM Heavy Duty, whether it’s the RAM 2500 or the RAM 3500, means driving a truck built for serious performance. But with great power comes the need for regular maintenance. Keeping up with your service schedule not only protects your investment but also ensures your truck keeps delivering the horsepower, towing capacity, and reliability it’s known for.

If you’re wondering, “How often should I service my RAM Heavy Duty?”—we’ve got you covered. Here’s a breakdown of the recommended maintenance schedule and why servicing at Monrovia Chrysler Dodge Jeep RAM is the smart choice.

Oil Changes and Routine Checks

For most drivers, oil changes should be performed every 7,500 miles or once a year, whichever comes first. RAM recommends synthetic oil for optimal performance, especially if you’re towing or hauling regularly. At these intervals, technicians will also:

  • Replace the oil filter
  • Rotate the tires
  • Inspect brakes and suspension
  • Check fluid levels and battery health

30,000-Mile Service

At around 30,000 miles, it’s time for a deeper inspection. This service may include:

  • Replacing the engine and cabin air filters
  • Checking the transfer case and differential fluids (especially for 4×4 models)
  • Inspecting the cooling system, suspension, and exhaust
  • Brake inspection and potential pad replacement

60,000-Mile Service

By the time you hit 60,000 miles, your RAM Heavy Duty has done some serious work. At this milestone, service typically includes:

Replacing spark plugs (for gas engines)
Inspecting and possibly replacing brake pads and rotors
Transmission fluid and filter check
Checking belts and hoses for wear

90,000-Mile Service

The 90,000-mile service is all about keeping your truck road-ready for the long haul. Key steps often include:

  • Full cooling system flush
  • Fuel system cleaning
  • Replacing worn belts or hoses
  • Comprehensive inspection of the drivetrain and suspension

Think of this as a “reset” to keep your RAM performing like new well past the 100,000-mile mark.

Sticking to the recommended maintenance schedule is the best way to get the most out of your 2026 RAM 2500 or 3500. From oil changes to 90,000-mile milestones, Monrovia CDJR is here to keep your truck running strong.
