Air springs for the Jeep Grand Cherokee Wk start at low prices, and AutoBuffy stocks multiple options from top OE-quality brands. An air spring replaces a conventional coil spring by using a pressurized rubber bladder to support the vehicle's weight and absorb road impacts. When one fails, the corner sags, the ride turns harsh, and the compressor runs constantly trying to compensate — causing a chain of expensive secondary damage.
The main decision is whether to replace the failed air spring with an OE-style air bladder, a complete strut-and-spring assembly, or to convert the system to passive coil springs entirely. Your budget, how long you plan to keep the vehicle, and whether other air suspension components are already worn will determine the best path. Position — front or rear — also matters, as the designs and load ratings differ.
| Option | Best for | What you get |
|---|---|---|
| OE-style replacement air spring (bladder only) | Owners who want to preserve the factory air suspension and whose compressor and valves are still healthy | A direct-fit rubber or sleeve-style bladder that restores original ride height and comfort with minimal additional parts |
| Complete air strut assembly (spring + strut + mount) | Front positions or any corner where the strut, mount, or bump stop is also worn | A pre-assembled unit that eliminates multiple failure points at once and often requires no spring compressor to install |
| Rear air spring with internal bump stop | Rear positions on trucks, SUVs, and luxury vehicles carrying variable loads | A self-contained bladder with a built-in jounce bumper that prevents metal-to-metal contact under full compression |
| Coil spring conversion kit | High-mileage vehicles where the compressor and other air suspension components are also failing, or owners who want to eliminate future air system costs | Passive steel coil springs and passive struts or shocks that permanently replace the air suspension — no compressor required, modest ride quality trade-off |
The vehicle must be raised and supported securely, and on electronically controlled systems the air suspension should be vented or set to service mode before disconnecting any air lines to avoid pressurized line injuries. The air spring bladder or complete strut assembly is unbolted from its upper mount and lower perch, the air line fitting is disconnected, and the new unit is installed in reverse order. After installation, a suspension height calibration with a compatible scan tool is recommended before returning the vehicle to normal operation.
