The 2011 Jeep Grand Cherokee also has all-new independent front and rear suspension designs. They feature isolated front and rear suspension cradles along with variable-rate rear springs to deliver improved on-road handling and comfort while complementing the vehicle's renowned off-road capability.

The rear suspension boasts a class-leading 10.2 inches of travel to maintain legendary Jeep attributes.

The new rear suspension also allows the spare tire to be stored inside the vehicle rather than underneath, for added convenience.

Load-leveling shocks are also available. These shocks react to payload levels and mechanically increase vehicle height when the vehicle has added rear payload. When payload is added to the vehicle, the shocks' gas pressure increases until the vehicle. reaches normal ride height.

Advantages to load-leveling shocks include improved load handling and trailer-tow performance. Load-leveling shocks are available with Trailer-Tow packages (except V6 4x2 models) that do not already have the Quadra-Lift Air Suspension.
