Firm up the back end of your Z with the KYB Gas-a-just shock absorber KG5787A, a high-pressure monotube gas shock that installs as a REAR direct-fit replacement for the 1984-1989 Nissan 300ZX. This KYB shock absorber is an OE monotube replacement designed to restore your vehicle's original ride and control, with components and valving developed specifically for the 300ZX.
High-pressure monotube design: separates the gas and oil for fade-free operation and instant response.
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.
Triple chrome-plated piston rod: an ultra-smooth rod that reduces seal wear; fluid leaking can be a cause of shock failure.
Added damping: adds up to 25% more damping performance over original-equipment shocks, with extra damping for vehicles that work, tow, and run larger, heavier tires and wheels.
The higher gas pressure responds quickly to help improve steering response, and KYB notes the Gas-a-just helps keep electronic safety systems performing as designed. Sold individually; replace the rear shocks as a matched pair for balanced handling.
