KYB Gas-a-just Rear Strut for Jaguar XJ and XJS

The KYB Gas-a-just KG9122 is a rear suspension strut built for Jaguar XJ, XJ12, and XJS applications that need OE-style control with added damping response. Its monotube design separates gas and oil for consistent operation, while the high-pressure gas charge supports quicker steering response and stable ride control.

Gas-a-just Product Line Details

KYB Gas-a-just struts are designed as monotube OE replacements for vehicles that carry heavier loads, tow, or use larger wheels and tires. The KG9122 uses an air-free hydraulic working area for responsiveness and a separate nitrogen gas chamber with a floating piston to maintain ride comfort during normal driving and deliver firmer control when suspension demand increases.

Key Features

  • Part number KG9122 for rear suspension service on select Jaguar models
  • Adds up to 25% more damping performance over original equipment shocks
  • High-pressure monotube construction separates gas and oil for fade-resistant operation
  • Ultra-smooth triple chrome plated piston rod helps reduce seal wear and fluid leakage
  • Designed specifically for Jaguar XJ fitment and related rear applications
  • Supports improved steering response through higher gas pressure
  • Includes a dust cover and bumper assembly

Detailed Description

KYB KG9122 is a rear suspension strut engineered for direct replacement use on 1968-1971 Jaguar XJ, 1972-1986 Jaguar XJ6, 1973-1979 Jaguar XJ12, 1981-1986 Jaguar XJ12, and 1976-1995 Jaguar XJS rear applications. The monotube layout keeps the gas and oil chambers separate, which helps maintain consistent damping during repeated suspension movement. For Jaguar XJ and Jaguar XJS owners looking for a firmer OE-style ride, KG9122 provides a controlled response without changing the vehicle’s original suspension layout.

This part cross-references Monroe Shocks & Struts 39003 for the same application.

  • Excessive rear-end bounce or oscillation
