Firm up rear damping and keep your classic Nissan planted with the KYB Gas-a-just Suspension Strut KG9101, a high-pressure monotube gas unit. It installs as a direct-fit rear replacement for the 1979-1981 Nissan 280ZX, 1977-1981 Nissan 810, and 1981-1984 Nissan Maxima. The monotube design separates the gas and oil so the strut resists fade due to aeration and responds instantly during normal driving.

  • High-pressure monotube design: Separates gas and oil for fade-free operation and instant response, with two working chambers — an air-free hydraulic piston/valve area for control and a nitrogen gas area with a floating piston.
  • Up to 25% more damping: Adds up to 25% more damping performance over original-equipment shocks, with components and valving designed specifically for Nissans (Datsuns).
  • Triple chrome-plated piston rod: An ultra-smooth triple chrome-plated rod helps reduce seal wear, since fluid leaking can be a cause of shock failure.

The higher gas pressure is designed to improve steering response, and KYB notes the Gas-a-just helps keep electronic safety systems performing as the vehicle manufacturer intended. Signs the rear damper may need replacing include excessive bounce, nose dive, or fluid seepage.
