2026 Ram 3500
Frequently Asked Questions

The 2026 Ram 3500 is a specialized tool designed for the most demanding jobs in Kingfisher County. Because it often serves as a primary business asset, buyers have technical questions that go far beyond standard brochure specs. Our service and sales teams have compiled the 10 most frequent questions we receive about the 2026 Heavy Duty lineup.
How wide is the 2026 Ram 3500 Dually?
The 2026 Ram 3500 Dual Rear Wheel (DRW) model measures 96.5 inches wide at the rear fenders. This is 13 inches wider than the Single Rear Wheel (SRW) version, which is 83.5 inches wide. This extra width is important to consider for garage doors, narrow parking areas, and bank drive-through lanes in Kingfisher.
What is the maximum towing capacity of the 2026 Ram 3500?
When equipped with the High Output 6.7L Cummins Diesel and a 4.10 axle ratio, the 2026 Ram 3500 delivers a segment-leading 36,610 pounds of maximum towing capacity. This rating requires a properly equipped gooseneck or fifth-wheel hitch.
Does the 2026 Ram 3500 still offer a manual transmission?
No. Ram discontinued manual transmissions in the Heavy Duty lineup several years ago. All 2026 Ram 3500 trucks use a six-speed automatic transmission. Standard Output models feature the 68RFE, while High Output models are paired with the commercial-grade Aisin AS69RC.
How much torque does the High Output Cummins produce?
The 2026 High Output 6.7L Cummins Turbo Diesel produces 1,075 lb-ft of torque and 430 horsepower. Peak torque is achieved at just 1,800 RPM, delivering exceptional pulling power at low speeds.
Can I get the High Output engine in a Single Rear Wheel (SRW) truck?
Yes. For the 2026 model year, Ram allows the High Output Cummins engine and Aisin transmission to be paired with Single Rear Wheel configurations on select trims. This option is ideal for drivers who want maximum torque without the full width of a dually.
What is the fuel tank capacity for the Ram 3500?
Fuel tank size depends on cab and bed configuration:
- Crew Cab with 6'4" bed: 31 gallons
- Crew Cab with 8' bed: 50 gallons
- Mega Cab: 32 gallons
What are the service intervals for the Aisin transmission?
The commercial-grade Aisin AS69RC requires more frequent service than the standard automatic. Under severe-duty use - including most towing and farm work in Oklahoma - the transmission fluid and filter should be changed every 30,000 miles.
How much Diesel Exhaust Fluid (DEF) does it hold?
The 2026 Ram 3500 is equipped with a 5.5-gallon DEF tank. Under normal driving conditions, a full tank can last several thousand miles, though DEF consumption increases significantly when towing heavy loads.
Is the Ram 3500 available with air suspension?
Yes. The available Auto-Level Rear Air Suspension is a popular option for Ram 3500 owners. It includes a Bed Lowering Mode for easier trailer hookups and automatically levels the truck when a heavy load is placed in the bed.
What is the max payload of the Ram 3500?
The maximum payload rating for the 2026 Ram 3500 is 7,590 pounds, achieved in a Regular Cab 4x2 configuration with the 6.4L Hemi V8. Diesel models have slightly lower payload ratings due to the additional weight of the Cummins engine.
