Gas Cartridge

KYB Excel-G Gas Cartridges restore your vehicle's original suspension performance with precision engineering. Built on the same OE assembly lines as factory components, these nitrogen gas-charged, twin-tube shocks and struts deliver the stability, handling, and stopping power your vehicle was designed to provide. Engineered to maintain OEM specifications rather than alter them, Excel-G cartridges earn their OEA (Original Equipment for the Aftermarket) designation through superior quality and calibration. Trusted by professional technicians for dependable ride control and responsive lane-change performance.

KYB Excel-G Gas Cartridges are engineered to support your vehicle's electronic safety systems by maintaining suspension performance exactly as the manufacturer designed it. Featuring industry-leading strut bodies and brackets with minimal flex, these cartridges preserve proper alignment under all driving conditions. The triple-lip fluid seal design reduces oil and gas leakage, while the OEM-recommended construction restores your vehicle's original control and handling characteristics. For optimal performance and longevity, pair with KYB Strut Boots (part SB104) to shield against dirt and salt, and consider new strut mounts (part S) to minimize noise and vibration during installation.
