KYB KG5534 Shock Absorber - Front or Rear

KYB Gas-a-Just Rear Shock Absorber

The KYB Gas-a-Just KG5534 is an OE-style monotube shock absorber built to restore original suspension control with quicker response and added damping. It is a strong match for rear suspension service on vehicles such as the Honda Passport, Isuzu Rodeo, and Isuzu Trooper, as well as select Mercedes-Benz rear applications.

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 adds instant performance when load or road demand increases
• Vehicle-specific valving and components for the listed applications
• Triple chrome plated piston rod helps reduce seal wear and fluid leakage
• Improves steering response through higher gas pressure and faster shock reaction
• Supports electronic safety systems by helping the suspension operate as the vehicle manufacturer intended

Product Details

The Gas-a-Just line is KYB’s monotube shock absorber series for drivers who want OE replacement performance with firmer control under demanding conditions. KG5534 uses two working chambers: an air-free hydraulic section for control and a high-pressure nitrogen section with a floating piston for comfort during normal driving and immediate damping when conditions change. This makes it a practical rear shock choice for a 1994-1997 Honda Passport, 1991-1997 Isuzu Rodeo, and 1987-1991 Isuzu Trooper, along with select Mercedes-Benz 300SE and 300SEL rear applications. This part cross-references Monroe Shocks & Struts (e.g., 37024) for the same application.

What It Helps Address

• Excessive rear bounce after bumps
• Reduced control when towing or carrying heavier loads
• Soft or delayed steering response from worn rear damping
• Fluid leakage caused by worn shock seals
• Loss of ride control on vehicles with larger tires and wheels
