The KYB Gas-a-just monotube shock absorber restores original ride control using two chambers: an air-free hydraulic piston and valve area for responsiveness, and a high-pressure nitrogen chamber with a floating piston for comfort and instant on-demand performance. It functions as an OE-style replacement and helps keep electronic safety systems working by maintaining proper suspension response. Fitment: rear for Buick Apollo (1973) and Buick Century (1973–1977) rear-wheel estate wagon applications.
