KYB Gas-a-Just Rear Strut for Nissan 280ZX

The KYB Gas-a-Just KG9113 is a rear suspension strut built as an OE-style monotube replacement for the Nissan 280ZX. It uses separate hydraulic and high-pressure gas chambers to deliver responsive control in normal driving with added damping when the suspension is working harder.

Key Features

  • Monotube design with separate gas and oil chambers for consistent response
  • Adds up to 25% more damping performance over original equipment shocks
  • High-pressure nitrogen gas helps maintain fade-free operation
  • Triple chrome plated piston rod helps reduce seal wear and fluid leakage
  • Designed specifically for the Nissan 280ZX rear suspension
  • Includes dust cover and bumper assembly
  • Supports steering response and electronic safety system performance by maintaining suspension control

Product Details

KYB Gas-a-Just struts are built for drivers who want OE replacement performance with firmer control than a standard twin-tube design. The KG9113 uses a high-pressure monotube layout that separates gas and oil, helping the strut react quickly and stay consistent under load. For the Nissan 280ZX, this rear strut is engineered to match the vehicle’s original suspension requirements while adding damping reserve for heavier wheels, towing, or more demanding road conditions. This part number, KG9113, is a direct-fit rear suspension strut for the 1981-1983 Nissan 280ZX rear application.

This part cross-references Gabriel G51232 and Monroe Shocks & Struts 71210 for the same application.

What It Helps Address

  • Excessive rear bounce or oscillation
  • Reduced damping control from worn original struts
  • Fluid leakage caused by seal wear
  • Slow steering response linked to weak suspension control
  • Loss of ride consistency under heavier loads or larger wheels
