What in the World is: Quadra Lift®?
What in the world is Jeep’s “Quadra Lift®” suspension? Well, for starters it’s what allows the Selec-Terrain 4WD System to quickly adjust the ride height of a vehicle to provide a safer and more reliable off-road experience and better handling during severe road conditions (video from Jeep below).
Now, let’s take a deeper dive into the Quadra-Lift® Air Suspension that was first available on the 2011 Jeep Grand Cherokee and has since made it’s way to other models including my personal favorite, the Jeep Cherokee Trailhawk. [UPDATED: I have since reached out to Chrysler after a comment was posted on our YouTube Channel by “rayamanelly” questioning the suspension height adjustment on the Jeep Cherokee Trailhawk. Chrysler has clarified that the information I initially referenced was incorrect and at the time of this writing the Quadra Lift® suspension is NOT AVAILABLE on the 2014 Jeep Cherokee Trailhawk and the Trailhawk DOES NOT make adjustments to ride height as previously stated.]
Note: Most of this information is hard to dig up on your own so I’m going to be citing a lot of Chrysler’s internal training material from the launch of the 2011 Jeep Grand Cherokee which provides a very comprehensive dive into the nuances of the Quadra-Lift® sytem.
“Quadra-Lift® is supported by four-corner air springs that provide a cushioned, premium ride. It operates automatically, or by means of console controls. It can function independent of the Selec-Terrain® system.
The Quadra-Lift® system features five height settings for optimum ride performance, each with its own benefits.
- Off-Road 2 (OR2) provides the maximum ride height of 2.6 extra inches (10.7 inches of ground clearance).
- Off-Road 1 (OR1) provides 1.3 extra inches (9.4 inches of clearance) for off-roading, but allows a bit more suspension comfort. This position provides a good balance between ground clearance and ride comfort.
- Normal (NRH) is the standard ride height and is best for all-around driving conditions. It offers 8.1 inches of clearance and provides the most comfortable balance of ride and handling.
- Aero lowers the vehicle just over a half inch to maximize aerodynamics and fuel economy at highway speeds. This position
also reduces body roll and provides a “sportier” feel.
- Park lowers the vehicle 1.5 inches below normal height to make entry/exit and loading/unloading easier.
The system also continually monitors passenger, cargo and trailer tongue weight and adjusts the air suspension automatically, to maintain a level ride.”
What does all this mean to you? Well it affords several benefits including:
- The ability to change the ride height with the push of a button
- Automatic four-corner load leveling
- Improved on-road comfort and improved fuel economy at highway speeds with the reduction of drag in Aero mode
- Improved off-road capability with increased ground clearence and easy of entry/exit and loading/unloading of cargo
- Also, as a result of the Quadra-Lift® closed system design (moves pressurized air from the reservoir to the air springs and back) adjustments are much faster than systems that must draw in or exhaust air for operation.
