Doc's Diesel 6.7L Cummins Filter Maintenance Kit — Fits RAM 2500–5500 (2019–2024), Oil Air Cabin Fuel/Water

Doc's Diesel Filter Maintenance Kit is a bundled replacement set of oil, air, cabin, and fuel/water separation filters engineered for 6.7L Cummins RAM 2500–5500 trucks from model years 2019–2024.

This all-in-one service pack gathers the exact filters required for a routine maintenance service, so you get matched components designed for the RAM 6.7L Cummins family without hunting part numbers. Components are independently tested for particle capture and dust-holding capacity, and the kit groups each filter needed for common intervals so a single purchase covers the next scheduled service.

Which vehicles and model years does this kit fit?

The kit is built to fit Ram trucks powered by the 6.7L Cummins diesel from 2019 through 2024, including 2500, 3500, 4500, and 5500 chassis where applicable. Use the fitment card on the product page to confirm compatibility with your specific cab, bed, and axle configuration before ordering.

• Compatible with 6.7L Cummins RAM 2500–5500 (2019–2024)
• Includes parts matched to the same application for a single-order service
• Check the vehicle fitment card for exact year/configuration match

How effective are the filters at capturing contaminants?

Independent lab testing verifies the kit's filtration performance rather than relying on manufacturer claims. Results show high efficiency and substantial dust-holding capacity, so the filters maintain flow while trapping fine particles.

• Overall efficiency tested at 99.25 percent
• 99.1 percent efficiency down to 3 microns
• Dust-holding capacity measured at 344.2 g, indicating longer effective service life

What components come in the maintenance kit and how do they save time?

This single kit contains all primary filters needed for a full service: engine air, oil, cabin air, and two fuel/water separators. By shipping matched parts together you avoid ordering individual items and ensure every filter is correct for the same vehicle application.

• DPA6314 engine air filter for intake protection
• D5335 oil filter for engine lubrication maintenance
• D3705 cabin air filter to help keep the cab air clean
• DGF430 and DGF401 fuel/water separators to protect the fuel system

How often should I replace these filters?

Replacement intervals depend on use and the vehicle manufacturer’s recommendations; the kit provides guidelines derived from typical service schedules. Follow your owner’s manual for warranty intervals and adjust for severe duty, towing, or off-road conditions.

• Fuel/water separators: change roughly every 5,000–10,000 miles (15,000 miles maximum in lighter conditions)
• Oil filters: change approximately every 5,000–7,000 miles (up to 10,000–15,000 miles in some conditions)
• Air and cabin filters: inspect at service intervals and replace as needed per manual

Who this kit is for: technicians, fleet managers, and Do-It-Yourself owners who maintain 6.7L Cummins-equipped RAM trucks and want a verified, time-saving option for scheduled service. If you prefer to buy all required filters in one box, need parts confirmed to fit your RAM 2019–2024, and value independently tested filtration performance, this bundle simplifies servicing while matching OEM-style applications.
