KYB KG4730 Suspension Shock Absorber - Front

KYB Gas-a-Just Front Shock for Jaguar XJ

KYB Gas-a-Just KG4730 is a monotube suspension shock absorber built as an OE-style replacement for select Jaguar XJ front applications. It is engineered to restore original ride control while adding firmer damping response for vehicles that carry extra load, larger wheels, or see more demanding driving.

Key Features

• Monotube design separates gas and oil for consistent response and fade-resistant operation
• Up to 25% more damping performance than original equipment shocks
• High-pressure nitrogen gas chamber delivers quicker steering response
• Triple chrome plated piston rod helps reduce seal wear and fluid leakage
• Includes dust cover, B-stop, and R-stop
• Designed specifically for Jaguar XJ front suspension applications

Product Details

The KYB Gas-a-Just line is built for drivers who want OE replacement control with added damping authority. Part number KG4730 uses a two-chamber monotube layout with an air-free hydraulic working area for responsiveness and a separate high-pressure gas section with a floating piston. That design helps maintain stable damping during normal driving and provides immediate performance when suspension demand increases. This KYB Gas-a-Just KG4730 shock absorber is a direct-fit front suspension component for select 1994-1997 Jaguar XJ6 and XJ12 models.

This part cross-references Monroe Shocks & Struts (e.g., 39016) for the same application.

What It Helps Address

• Excessive front-end bounce or oscillation
• Reduced steering response during braking or lane changes
• Shock fade under heavier driving demands
• Fluid leakage caused by seal wear
• Loss of ride control on Jaguar XJ front suspension systems

Installation Notes

Fits 1995-1997 Jaguar XJ6, front. Fits 1995-1996 Jaguar XJ12, front. Fits 1994 Jaguar XJ12, front. Fits 1994 Jaguar XJ6, front. Replace the suspension strut and coil spring assembly according to the manufacturer’s instructions where specified. Verify compressed length, extended length, and mount style before installation. This KYB KG4730 uses a special lower mount and S1 upper mount configuration.

Quality Assurance

KYB designs Gas-a-Just shocks as OE monotube replacements to restore factory suspension behavior with added damping capacity. The monotube construction, high-pressure gas charge, and chrome piston rod are selected to support consistent operation in front suspension service on Jaguar XJ applications.
