KYB Gas-a-Just rear shock for BMW 320 Series (1977-1983). The Gas-a-Just monotube design separates hydraulic and high-pressure nitrogen chambers with a floating piston to give responsive control and prevent aeration fade. Offered as an OE-style monotube replacement, it restores original damping; KYB recommends strut boot SB113 to protect new units from dirt and corrosion.
