Firm up worn rear suspension and help restore the designed control and handling of your Jeep with the KYB Excel-G Suspension Shock Absorber 344342. It installs as a direct-fit rear replacement for the 1999-2004 Jeep Grand Cherokee — see the Buyer's Guide tab for the full engine-level fitment. KYB is a world-leading supplier of shocks and struts to new-vehicle manufacturers, and the Excel-G is built on the same OE assembly lines using the same OE-quality components, calibrated to restore original designed performance rather than change it — earning it the OEA (Original Equipment for the Aftermarket) classification.
- Nitrogen gas-charged twin-tube design: includes every quality component found in KYB's global OEM products.
- Triple-lip fluid seal: reduces the chance of oil and gas leaking out.
- Vehicle-specific damping valves: hand assembled in-house to correctly manage tire contact, steering response and body movement.
- Strong, thick body and brackets: among the industry's thickest, minimizing flex to help maintain correct alignment in all conditions.
Because electronic safety systems depend on the suspension, brakes and tires operating as the manufacturer intended, the Excel-G helps keep those systems performing as designed. Sold individually; replacing both rear shocks together as a pair is recommended for balanced ride control.
