Help restore composed handling to your classic with the KYB shock absorber (P/N 343218), a nitrogen gas-charged Excel-G unit that installs as a direct-fit replacement in the rear position on the 1963-1982 Chevrolet Corvette. This KYB gas shock absorber is built on the same OE assembly lines KYB uses to supply new-vehicle manufacturers, earning the Excel-G its OEA (Original Equipment for the Aftermarket) classification — designed to restore the vehicle's original engineered ride control and handling, not change it.
Nitrogen gas-charged twin-tube design: the Excel-G construction helps manage damping consistently.
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.
KYB positions the Excel-G as the recommended OEM-style replacement shock and the choice preferred by professional technicians. Signs a rear shock may need replacing include excessive bounce over bumps, nose dive, sway, or fluid leakage — diagnose the cause before ordering. Sold individually; replacing rear shocks as a pair is recommended for balanced ride control.
