Understanding Jeep 4x4 Systems: Quadra-Trac I, II, and Quadra-Drive II Explained

Quadra-Trac I: Effortless Full-Time Traction for Daily Commutes

For many of our customers, the best technology is the kind that works behind the scenes without needing a lever or a button. Quadra-Trac I is a full-time, single-speed 4x4 system designed for exactly that. It uses a center differential to split power, sending about 48 percent to the front and 52 percent to the rear under normal conditions. Because it lacks a low-range gear, it is lighter and more straightforward than its more rugged siblings, making it a popular choice for those who prioritize efficiency and ease of use on paved roads.

This system is standard on the Laredo trim of the 2026 Jeep Grand Cherokee, which features a 2.0L I4 engine and an Automatic transmission. With an EPA-rated 21 city / 27 hwy, it provides a balanced performance profile for those commuting into the city. When the system detects wheel slip, it works with the brake actuated limited-slip differential to redirect torque to the wheels with the most grip. It is a "set it and forget it" solution that offers peace of mind during a sudden Oklahoma rainstorm or on a slick, ice-covered bridge.

If you are looking for this level of capability in a pre-owned model, we invite you to browse our used-car inventory to see various configurations. We also feature used vehicle specials that often include well-maintained Jeep SUVs equipped with this reliable system. For those who need significantly more muscle for work sites, we also stock heavy-duty Ram trucks that provide a different kind of specialized traction for heavy hauling.

Quadra-Trac II: Adding Low-Range Power for Tough Terrain

When your weekend plans involve more than just a gravel driveway, Quadra-Trac II provides the mechanical advantage needed for more demanding environments. The defining feature of this system is its active two-speed transfer case. Unlike the single-speed version, this unit includes a 2.72:1 low-range gear reduction. This allows for high-torque, low-speed crawling, which is essential for technical maneuvers or pulling a heavy trailer up a steep, slick boat ramp.

The terrain around Hinton transitions into more rugged hills as you get closer to the Wichita Mountains, and that is where the low-range capability of Quadra-Trac II truly shines. It can redirect up to 100 percent of available engine torque to the axle with the most traction the moment slip is detected. This system is often paired with the Selec-Terrain traction management system, allowing you to choose modes like Snow, Sand/Mud, or Rock. Each setting adjusts the Automatic transmission shifts and throttle response to match the ground beneath you.

You will find Quadra-Trac II available on several mid- to high-trim levels, including the Limited and the 85th Anniversary Edition. On the 2026 Jeep Grand Cherokee Limited, this system supports a 4WD drivetrain that pairs with the 2.0L I4 engine. While the Limited trim is listed at $50,404, it offers a significant jump in utility for those who explore off the beaten path. You can explore all new vehicles on our lot to compare these systems in person, or check out our new Ram 1500 selection if your needs lean more toward a pickup bed. We also maintain a high-quality selection of certified pre-owned models for those seeking factory-backed confidence in a used vehicle.

​

Quadra-Drive II: The Pinnacle of Off-Road Traction and Control

One of the most frequent questions we hear involves the difference between "good" traction and "ultimate" traction. Quadra-Drive II represents the highest level of 4x4 capability available for the 2026 Jeep Grand Cherokee. It utilizes the same two-speed transfer case as the previous system but adds a rear electronic limited-slip differential (ELSD). This addition is critical because it allows the vehicle to manage torque not only between the front and rear axles but also between the individual rear wheels.

In a situation where three wheels are on ice or mud and only one rear wheel has grip, Quadra-Drive II can send 100 percent of available torque to that single wheel. This is the system we recommend for the most adventurous drivers seeking the most challenging trails Oklahoma has to offer. It is standard equipment on the Summit trim, which starts at $65,185, and the off-road-focused Trailhawk. These models are designed to be "Trail Rated," meaning they have passed rigorous testing for traction, ground clearance, maneuverability, articulation, and water fording.

To make your upgrade easier, you can prequalify for financing online before you even visit the dealership. If you are looking for a more accessible entry point into this legendary capability, we often have used Grand Cherokees in stock that feature these premium drivetrains. Our inventory also includes a variety of used trucks for those who need a different set of tools for their outdoor lifestyle.

Answers to Your Toughest Jeep Drivetrain Questions

Q: What is the main difference between Quadra-Trac I and II?

The primary distinction is the transfer case. Quadra-Trac I is a single-speed system that is always active and requires no driver input, making it ideal for standard road conditions. Quadra-Trac II adds a two-speed transfer case with a low-range gear, which provides significantly more torque for off-road crawling and technical driving.

Q: Can I flat tow a Jeep with Quadra-Trac I?

No, you cannot flat-tow a vehicle with Quadra-Trac I because its single-speed transfer case doesn't have a neutral setting. For RV towing, you'll require a two-speed system like Quadra-Trac II or Quadra-Drive II, both of which feature a neutral mode that fully disengages the drivetrain.

Q: Is Quadra-Drive II standard on the 2026 Grand Cherokee Trailhawk?

Yes, Quadra-Drive II is the standard 4x4 system for the Trailhawk and Summit trims. It is designed to provide the highest level of traction by combining a two-speed transfer case with a rear electronic limited-slip differential, ensuring that power is sent to the wheel with the most grip even in extreme conditions.

Q: Which Jeep 4x4 system is best for fuel efficiency?

Generally, Quadra-Trac I is the most fuel-efficient option because it is a lighter, simpler system. The 2026 Jeep Grand Cherokee Laredo helps achieve an EPA-rated 21 city / 27 hwy. The more complex systems add weight and mechanical components that are essential for off-roading but can slightly impact overall efficiency.

Q: Should I call ahead to confirm which system a vehicle has?

Yes, the best way to ensure the hardware matches your towing needs before driving in. While our online listings are detailed, speaking with a member of our team is the safest way to verify the exact 4x4 configuration on a specific VIN.

If you have more questions or need a multi-point inspection on your current vehicle, our service department is staffed by factory-trained technicians. We also offer new vehicle specials and a great selection of new Ram trucks for those who need heavy-duty capability.
