How Do I Know If My Jeep Has Quadra-Lift? (Let’s See)
A vehicle’s height from the ground determines its fuel efficiency and off-road capabilities.
For this reason, a Quadra-Lift air suspension system is modified into many automobiles to give them a ride height advantage.
But how can you tell if your Jeep has this feature? This article answers that and more.
Usually, up and down suspension buttons on the control console indicate your Jeep has a Quadra-Lift. Generally, this control console is often behind the gear shift. Also, if you can see a large air unit behind the car’s wheel area, you have a Quadra-Lift system.
What Is a Jeep Quadra-Lift?
The Quadra-Lift Air Suspension is an automatic height adjustment system. In other words, you don’t have to stop your Jeep from raising or lowering the suspension.
With that said, the Quadra-Lift System can adjust the vehicle’s height depending on the driving mode you choose.
In addition, this mechanism can raise your vehicle for better maneuvering in off-road conditions.
Also, when your car is parked, the Quadra-Lift Air suspension can be set to lower the Jeep for easy access. The Limited and Overland models started using the feature in 2010.
The Quadra-Lift is unique because of the air springs it uses at each wheel instead of normal coil springs.
Further, this advanced spring can raise and lower your vehicle automatically at the touch of a button. You can control this feature using two buttons found near the drive mode selector.
To have a palm-full knowledge of a Jeep Quadra-Lift system, you’d have to know what this feature does.
So, I’ll now outline some capabilities of a Quadra-Lift.
#1. Better Ground Clearance
The Quadra-Lift, as the name implies, gives your Jeep a lift. That, in turn, provides better ground clearance for your Jeep.
With better ground clearance, your Jeep is better equipped to handle challenging terrains, and navigating through rocks or deep snow.
#2. Improve Fuel Efficiency
With the control console, the Quadra-Lift Air Suspension can reduce the overall height of your automobile.
When this happens, it gives the Jeep a more aerodynamic profile, which helps improve fuel economy.
In addition, if a vehicle is low, it paves its way easily through the wind and becomes more efficient.
#3. Automatic Operation
One amazing thing about this air suspension device is its ability to adjust the car’s height while in motion automatically.
However, this is based on the selected drive mode. This operation happens so smoothly that you won’t feel the change in your vehicle’s height until you stop and observe.
#4. Ease Vehicle Access
The height of certain vehicles makes it difficult to enter and come out of them. Now, the Quadra-Lift system gives you the ability to lower the car for easier entry and exit.
Also, when your Jeep is low, it gives easy accessibility to the roof rack and facilitates loading and unloading.
How Does Jeep Quadra-lift Work?
Unlike most vehicles’ suspensions, the Quadra-Lift doesn’t use traditional coil springs at each wheel. Instead, it has an Air Suspension system that uses air springs.
The air springs enable your vehicle to elevate or depress across 4.1 inches. This adjustment capability makes the automobile flexible to improve fuel efficiency on the highway.
Furthermore, the air suspension provides extra ground clearance for off-road terrain.
Equally important, according to your selection, the Quadra-Lift can function independently of the Selec-Terrain system.
Now, consider some ride modes with Quadra-Lift and how they work.
#1. Normal Ride Height
The Normal Ride Height or NHR is also known as the standard Suspension height. Consequently, this is the height of the automobile that is best suited to all-around driving conditions.
Keep in mind that this model offers 8.1 inches of ground clearance.
#2. Off-Road 1 Mode
OR1 Drive Mode suits less severe Off-roading conditions. With 9.4 inches of clearance, it provides a good balance and ground clearance to overcome obstacles.
When the vehicle goes beyond 50 mph, the Air Suspension Control Module(ASCM) switches to NRH and lowers the suspension automatically.
#3. Off-Road 2 Mode
The OR2 Drive Mode offers a full Off-roading capability. With superior clearance, it can help you from getting snagged on logs or boulders.
It has a height of 10.7 inches for maximum suspension maneuvering. Keep in mind that driving faster than 25 mph can switch the system to OR1 and lower the suspension.
#4. Aero Mode
This Drive Mode lowers your vehicle by 0.5 inches from the normal ride height. This change reduces aerodynamic drag for better fuel economy at highway speeds when this happens.
In Aero Mode, you’ll experience improved ride comfort and the sportier suspension feels. Also, this drive mode automatically engages when the vehicle speed exceeds 66 mph.
#5. Park Model
The Park Mode can decrease the car by 1.5 inches from the standard height when the vehicle is parked.
With the Jeep close to the ground, accessing it becomes more convenient.
Additionally, Park Mode makes entry, exit, cargo loading/unloading, and having access to the roof rack comfortable.
Can You Disable Quadra-lift?
Of course, you can disable the Quadra-Lift Air Suspension system. To disable the Quadra-Lift, you’d have to press and hold the up and down suspension buttons for 5-10 seconds.
After that, a signal, either by sound or screen notification, would indicate that the Quadra-Lift system has been disabled.
If successfully disabled, a deactivation message will appear on the Electronic Vehicle Information Center (EVIC).
Moreover, it’s best to disable the air suspension before working under a vehicle. It’s essential to prevent unexpected raising or lowering of the car during a repair or service.
How to Determine if My Jeep Has a Quadra-Lift?
You can know if your Jeep has a Quadra-Lift by confirming the factory equipment used to make the car.
First, however, you have to input your VIN in the FCA Build Sheet to get the building sheet of your vehicle.
Usually, You can find this Vehicle Identification Number (VIN) on the body of your Jeep or related documents.
You can look for this identification number on the metal plate on the driver’s side of the dashboard. Most times, the digits are viewable from the outside.
However, the VIN can also be located at your vehicle’s door pillar, where the door latches to the car’s body.
Nevertheless, the number can also appear in front of the engine block. Other than that, you can also confirm whether your automobile has a Quadra-Lift system by checking the wheels.
Look inside or behind any tires of your Jeep. If you find an air unit instead of the traditional coiled springs, your vehicle has a Quadra-Lift.
This method is the easiest way to know if your car has Quadra-Lift.
Which Jeep Models Have Quadra-Lift?
Many 2021 Jeep Grand Cherokee trims like the rugged Trailhawk come with the Quadra-Lift Air Suspension technology.
More in this category are the Summit, High Altitude, and Overland models, which also have the feature.
In addition, the Jeep Grand Cherokee Limited trim has this air suspension too and other enticing packages.
Furthermore, the Quadra-Lift system is usually paired with the Selec-Terrain traction management system.
So, this gives you the option of driving in any mode that best suits a given terrain situation.
Conclusion
There are several ways to Know if your Jeep has a Quadra-Lift Air Suspension system. One of them is checking whether there are suspension buttons inside the car near your gear shift.
Similarly, you can inspect the wheel area to see if there’s an air unit; or confirm the car’s equipment using the VIN.
