H&R Sport lowering Springs 1.2 & 2.2 Jeep Grand Cherokee 2011-2021

German-Engineered Sport Springs That Drop and Sharpen the WK2 Grand Cherokee

The H&R Sport lowering springs for the 2011-2021 Jeep Grand Cherokee are a direct bolt-on upgrade that lowers the front approximately 1.2 inches and the rear approximately 2.2 inches 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 eliminates the oversized fender gap that makes the stock WK2 look soft. Drop rates vary slightly by engine, options package, and axle load, but the front-to-rear ratio is tuned to keep the stance level and the handling neutral.

Progressive Rate Design

H&R builds these Sport springs with a progressive spring rate rather than a linear rate. 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. The result is a spring that feels more compliant than a fixed-rate performance spring at cruise, but firms up exactly when the chassis needs support. This characteristic makes the H&R Sport springs compatible with the factory Jeep electronic suspension dampers as well as most aftermarket shocks sized for the WK2 platform.

Material and Manufacturing

Every H&R Sport spring is wound from 54SiCr6 high-alloy spring steel, the same base material used in motorsport applications. The wire is shot peened after forming to compress the surface grain structure and dramatically increase fatigue resistance under repeated load cycles. Each spring is then block set, a process that pre-loads the coils to eliminate settling after installation, so the drop figure you measure on day one is the drop you keep. A powder coat finish seals the steel against road moisture, salt, and brake dust. All manufacturing and quality testing happens at H&R's facility in Lennestadt, Germany.

Fitment Notes

These springs fit all 2011-2021 Jeep Grand Cherokee WK2 models with conventional coil spring suspension, including Laredo, Limited, Overland, Summit, and Trailhawk trims. It is not designed for SRT8 or SRT models, which use a different spring perch geometry and lower OEM ride height. H&R produces a separate part number for SRT applications. Professional installation and a full four-wheel alignment are required after fitting. Drop figures vary slightly depending on the vehicle's installed axle load and options.

Frequently Asked Questions

The H&R 28888-1 lowers the front approximately 1.2 inches (30mm) and the rear approximately 2.2 inches (55mm). Drop figures are approximate and vary slightly depending on the vehicle's installed axle load, engine option, and trim-specific equipment. The rear drops more than the front to level out the factory rake and produce a balanced stance.

Yes. The 2021 model year is the final year of the WK2 Grand Cherokee platform and shares the same spring perch geometry as 2011 through 2020 models. These springs are a confirmed fit for all non-SRT WK2 trims through the full 2011-2021 production run.

Yes. H&R designs these Sport springs to work with the factory OEM shock absorbers. On older vehicles with high mileage, H&R recommends replacing the shocks at the same time as the springs to get the full benefit of the progressive rate design. The springs are also compatible with most aftermarket shocks built for the WK2 platform.

No. These springs are designed for Grand Cherokee models with conventional coil spring suspension. It is not compatible with Jeep's Quadra-Lift air suspension system. Vehicles equipped with Quadra-Lift require a different conversion kit or air suspension-specific lowering solution.

No. The SRT8 and SRT models use a different spring perch geometry and a lower factory ride height than non-SRT trims. H&R produces part number 28888-2 specifically for SRT and SRT8 Grand Cherokee applications. Installing 28888-1 on an SRT model will produce incorrect drop figures and handling characteristics.

Yes, a full four-wheel alignment is required after lowering spring installation. Changing the ride height alters the camber and toe settings beyond stock tolerances. Driving without an alignment after installation will cause accelerated and uneven tire wear and can affect handling predictability. Budget for the alignment when pricing the full job.

H&R covers these springs with their Limited Lifetime Warranty against defects in materials and workmanship. Under the Magnuson-Moss Warranty Act, installing these springs on your Jeep Grand Cherokee cannot void your vehicle's factory powertrain warranty unless a dealer can demonstrate that the springs directly caused a specific failure.

The progressive rate design keeps daily ride quality close to stock under light loads. The ride firms up noticeably under hard cornering and braking, which is the intended behavior. Most owners describe the H&R Sport spring ride as slightly firmer than stock but significantly more controlled, with less float and body motion on highway on-ramps and winding roads. Ride harshness over sharp impacts increases modestly compared to stock, as expected with any lowering spring.

Professional installation is strongly recommended. The front struts require a spring compressor to safely disassemble. Improper spring compression is a serious safety risk. The rear springs are accessible without a compressor on the WK2 platform, but the job still requires lifting the vehicle, supporting the rear axle, and carefully managing spring tension. A professional shop with the correct equipment will complete the install safely and can perform the required alignment in the same visit.

Installation Overview

The front springs require strut disassembly using a spring compressor. With the vehicle raised and supported, remove the front wheel, unbolt the strut from the knuckle, compress the spring safely, swap the factory spring for the H&R unit, reassemble, and reinstall. The rear springs on the WK2 sit between the axle and the body. Support the rear axle, lower it to release spring tension, remove the factory springs, and seat the H&R springs in the upper and lower perches before raising the axle back into position. Torque all fasteners to factory specification. A four-wheel alignment must be performed after installation. Full instructions are included with the springs.
