Quadra-Lift

The class-exclusive Jeep Quadra-Lift air suspension, now with electronic adaptive damping, delivers class-leading ground clearance and water fording. The system automatically adjusts the shock tuning to changing road conditions for enhanced comfort, stability and control.


The 2021 Jeep Grand Cherokee L’s Quadra-Lift system operates automatically, or may be controlled manually with console controls, and features five height settings for optimum ride performance:

  • Normal Ride Height (NRH): 8.3 inches (212mm) of clearance offers improved fuel economy, as well as improved aerodynamics during on-road driving
  • Off-road 1: Lifts the vehicle an additional 1.6 inches (40mm) from NRH for added height in clearing obstacles (9.9 inches)
  • Off-road 2: Delivers legendary Jeep off-road capability and provides an additional 2.4 inches (60mm; 9 percent more range than previous generation) from NRH for increased, best-in-class ground clearance of 10.9 inches and up to 24 inches of water fording depth (improvement of four inches over previous generation)
  • Park Mode: Lowers 1.8 inches (46mm) from NRH for easy ingress/egress, which levels down the vehicle twice as fast over the previous generation. NRH and Park Mode are driver selectable, giving the driver full control over vehicle ride height. Air suspension improvements include a dual tank design to enable more controlled and quicker functionality
  • Aero Mode: Lowers the vehicle 0.8 inches (21mm) from NRH. Aero Mode is controlled by vehicle speed and adjusts for optimal performance and fuel economy. The vehicle will also lower to Aero Mode when in Sport Mode

Quadra-Lift adds up to 4.17 inches (106mm) of lift span supported by four-corner air springs that provide an air cushioned, premium ride. The crawl ratio on the Grand Cherokee L is 44:1.

 

With the available Quadra-Lift air suspension, the 2021 Jeep Grand Cherokee L features a 30.1-degree approach angle, a 23.6-degree departure angle and 22.6-degree breakover angle.

 

Selec-Terrain

The 2021 Grand Cherokee L’s class-leading Selec-Terrain traction management system lets customers choose the on- and off-road setting for optimum 4x4 performance. This feature electronically coordinates up to six different powertrains, 4x4 torque split, braking and handling, steering and suspension systems, including throttle control, transmission shift, transfer case and traction control, stability control, anti-lock braking system (ABS) and steering feel.

 

The Selec-Terrain system offers five available terrain modes (Auto, Sport, Rock, Snow, Mud/Sand) to provide optimized calibrations for any given driving scenario.

 

Hill-descent Control allows drivers to control Grand Cherokee L’s speed down steep, rugged grades with electronic paddle shifters standard on all models, without the need for throttle or brake pedals. Hill-descent Control is standard on Overland and Summit models and works both in forward and reverse.

 

When equipped with the available Off-Road Group, the Trail Rated Overland 4x4 model benefits from class-leading traction, ground clearance, maneuverability, articulation and improved water fording (capable up to 24 inches). The Off-Road Group also includes high-strength steel skid plates, electronic limited slip differential rear axle, 18-inch aluminum wheels and rugged, all-season performance tires.
