KYB Suspension Shock Absorber P/N:KG5548
Restore firm, controlled damping to the front of your classic with the KYB Gas-a-just Shock Absorber (KG4517), a high-pressure monotube gas shock absorber that drops in as a front replacement for the 1964-1970 Ford Mustang, 1967-1970 Mercury Cougar, 1970-1977 Ford Maverick, 1971-1977 Mercury Comet, and 1974-1976 Bricklin SV-1. This KYB gas shock absorber uses a monotube design that separates the gas and oil, so it resists fade even during hard, sustained driving.
How it works: The Gas-a-just has two working chambers — an air-free hydraulic piston and valve area for responsiveness and control, plus a high-pressure nitrogen gas area with a floating piston for a comfortable ride during normal driving with added performance on demand.
