Description
The H&R Sport lowering spring kit for the 2011–2021 Jeep Grand Cherokee WK2 is a vehicle-specific lowering spring kit for the applications listed below. Match manufacturer part number 28888-1, vehicle or wheel configuration, dimensions, position, included hardware, and package quantity before ordering.
Key Features
- The H&R Sport lowering springs for the 2011-2021 Jeep Grand Cherokee WK2 are a vehicle-specific spring kit with published approximate lowering figures of approximately 1.2 inches at the front and 2.2 inches at the rear on non-SRT and non-SRT8 models.
- Part number 28888-1 is precision wound from 54SiCr6 spring steel, shot peened, block set, and powder coated in Germany.
- The lower ride height reduces the center of gravity, cuts body roll in corners, and may reduce fender gap depending on vehicle equipment and existing ride height.
- Under light load and normal road conditions the spring acts softer, absorbing small bumps and maintaining daily-driver comfort.
- As load increases through cornering, braking, or rough pavement, the rate stiffens progressively to control body motion and keep the tires planted.
- Every H&R Sport spring is wound from 54SiCr6 high-alloy spring steel, a high-strength spring material.
Before Ordering: Confirm the exact H&R part number against the vehicle year, trim, factory coil or air suspension, axle loads and drivetrain. The listed year range does not guarantee fitment for every Grand Cherokee variant. Follow the manufacturer application notes before installation.
