The KYB Gas-a-just monotube shock absorber has additional performance advantages over the traditional twin-tube design: It can instantly, automatically adjust to your performance needs and never experiences fade due to aeration. The KYB Gas-a-just has two separate working chambers: An air-free hydraulic piston and valve area for responsiveness and control, and a second high-pressure nitrogen gas area with a floating piston that provides a comfortable ride during normal driving and adds instant performance on demand.This Part Fits: Year Make Model Submodel 1987-1991 Avanti II Base 1973-1977,1980-1981 Buick Century Base 1975-1979 Buick Century Custom 1980-1981 Buick Century Estate 1976 Buick Century Indianapolis 500 Pace Car 1978-1981 Buick Century Limited 1973-1975 Buick Century Luxus 1975-1979 Buick Century Special 1978-1981 Buick Century Sport 1970-1972 Buick GS Base 1968-1969 Buick GS 350 Base 1968-1969 Buick GS 400 Base 1970-1972 Buick GS 455 Base 1970 B
