Does the 2026 Ram 3500’s Exhaust Brake Control Speed Safely on Kerrville, TX Hill Grades?

Allways Atascosa Ram – Does the 2026 Ram 3500’s Exhaust Brake Control Speed Safely on Kerrville, TX Hill Grades?

Hill Country drivers know those gentle-looking grades around Kerrville can stretch into long, winding descents—especially along I-10, TX-16 toward Bandera, and the river valleys heading out past Ingram and Hunt. If you’re towing a fifth-wheel, gooseneck, stock trailer, or a heavy equipment trailer, you want confident, predictable speed control without riding your service brakes. That’s why in-market shoppers ask us about the 2026 Ram 3500’s available Automatic Smart Exhaust Brake and whether it truly helps on our local hills. The short answer is that it’s designed precisely for these conditions—and when paired with the High-Output 6.7L Cummins® Turbo Diesel I6 and the TorqueFlite® HD eight-speed automatic transmission, it becomes one of the 3500’s most valuable real-world features for Hill Country towing.

At Allways Atascosa Chrysler Dodge Jeep Ram, we spend a lot of time helping customers set up trucks for Kerr County ranch roads, weekend trips to Kerrville-Schreiner Park, and those steady descents east toward Comfort. Here is how the 2026 Ram 3500’s exhaust brake works, why it matters on our grades, and how to configure your truck for stable, low-stress downhill towing.

What the exhaust brake does—and why it matters here

A diesel exhaust brake uses engine backpressure to help slow the truck and trailer, reducing how often you touch the service brakes and how hard they need to work. The available Automatic Smart Exhaust Brake on the 2026 Ram 3500 manages this process seamlessly, helping the truck maintain set speeds more easily while minimizing heat buildup in the brake system. On extended Kerrville descents—think those gradual but lengthy stretches along I-10 or the rolling drops on TX-16—this translates to less brake fade and a calmer tow.

In the 2026 Ram 3500, the exhaust brake pairs with the High-Output 6.7L Cummins® Turbo Diesel I6 (430 max horsepower and up to 1,075 lb-ft of torque) and the TorqueFlite® HD eight-speed automatic transmission. That combination is built for heavy loads, with intuitive shift logic that plays nicely with the exhaust brake’s added retarding force. If you’re towing near the truck’s massive available diesel towing capacity of up to 36,610 pounds, that coordination is exactly what you want when gravity starts pulling.

How the 3500 supports you on long Hill Country descents

The exhaust brake is one important layer in a broader control system. Ram Heavy Duty trucks bring serious stopping power with Heavy-Duty Four-Wheel Disc Antilock Brakes, and the 3500 adds driver-assist technologies that maintain confidence even with a trailer attached. Forward Collision Warning with Active Braking can help bring the truck to a complete stop—even while towing—if it detects an imminent collision. Class-Exclusive standard Adaptive Cruise Control can help maintain a set following distance and can work its way down to 0 mph as traffic slows, adding peace of mind on busy stretches near Kerrville where elevation changes meet congestion.

Visibility tools help, too. The available Digital Rearview Mirror with side camera integration can show left and right views down the trailer’s flanks, and the available wired Tow Mode Camera offers a view behind the trailer. For a broader picture at lower speeds, the available 360° Trailer Surround View Camera can present a bird’s-eye perspective to help you stay centered in your lane or line up smoothly at a scenic riverside campsite along the Guadalupe.

Smart setup tips for Kerrville’s rolling grades

Before you tackle a long, steady downhill with a heavy trailer, a few simple steps can make your day easier. Here is how many of our Hill Country customers configure their 2026 Ram 3500 for calm, controlled descents.

• Pre-select exhaust brake: Engage the available Automatic Smart Exhaust Brake before you start your descent so it can assist from the top.
• Let the transmission work: The TorqueFlite® HD eight-speed automatic’s intuitive software helps hold appropriate gears—avoid constant manual intervention unless needed.
• Use your visibility tools: Activate the available Digital Rearview Mirror views and, when appropriate, the 360° Trailer Surround View Camera to maintain awareness around the trailer.
• Monitor trailer tires: Use available Trailer Tire Pressure Monitoring in the 12-inch Digital Cluster Display to confirm your trailer pressures are set for load and temperature swings.
• Leverage Trailer Tow Pages: Check Trailer Light Check and Trailer Brake Status through the available Trailer Tow Pages before you roll.
• Consider suspension support: If you spec Class-Exclusive available Auto-Level Rear Air Suspension, verify your truck is level for optimal stability at speed.

Taken together, these steps help you keep your speed where you want it, limit brake use to short, light applications, and maintain a steady, predictable line—even if you catch a gust across an exposed ridge west of Kerrville.

Which powertrain is right for your routes?

If downhill control on Kerrville’s hills is a weekly reality, the available High-Output 6.7L Cummins® Turbo Diesel I6 is your go-to because it is the one that offers the available Automatic Smart Exhaust Brake. It also brings that Best-in-Class available base diesel torque and up to 36,610 pounds of available diesel towing capacity for big fifth-wheels and goosenecks common around the Hill Country.

Prefer a gas setup for mixed duty and payload? The 6.4L HEMI® V8 offers refined performance with up to 7,590 pounds of maximum gas payload and up to 18,150 pounds of maximum gas towing capacity. It does not use an exhaust brake—that’s a diesel-only advantage—so your downhill routine will rely more on gearing and service brakes. If your trailer is lighter and your routes are shorter, the gas engine remains a confident option. For frequent heavy towing over Hill Country grades, diesel is the confidence play.

Tech that adds confidence beyond the brake pedal

The 2026 Ram 3500’s technology suite helps you stay focused and informed when the road falls away in front of you. A Largest-in-Class available 14.5-inch infotainment touchscreen with Uconnect® 5 NAV keeps tow-specific navigation and key apps close at hand. The available 12-inch Digital Cluster Display can show Trailer Tow Pages, including Trailer Brake Status, while available Trailer Tire Pressure Monitoring keeps an eye on up to four trailers—ideal if you rotate between a livestock hauler and a travel trailer.

On tighter Hill Country turnouts or campground switchbacks, available Trailer Reverse Steering Control uses a dedicated knob to command the trailer while the truck handles steering—this makes staging at river access points or backing into a sloped spot near Ingram feel far less stressful. And the Class-Exclusive available Power Convex Trailer Tow Mirrors with available mirror-mounted cameras help you keep your bearings when lanes narrow and shoulders disappear.

Before you head out, take a few minutes to run a consistent downhill checklist. These quick steps prevent surprises and give you a clear plan before gravity gets involved.

1. Verify connections: Confirm hitch, safety chains, electrical plug, and breakaway cable are all secure.
2. Confirm lights and brakes: Use Trailer Tow Pages for a Trailer Light Check and verify trailer brake operation.
3. Set the exhaust brake: Engage the available Automatic Smart Exhaust Brake at the crest, not mid-slope.
4. Dial in visibility: Turn on the available Digital Rearview Mirror’s side camera views for lane awareness.
5. Check pressures: Review available Trailer Tire Pressure Monitoring for each tire on your loaded trailer.
6. Plan your path: Use Uconnect® 5 NAV to identify longer turnouts or gentler routes if you prefer less grade.
