KYB KG5198A Shock Absorber - Rear

KYB Gas-a-Just Rear Shock for Mazda MPV

KYB Gas-a-Just KG5198A is a rear suspension shock absorber for the 1989-1998 Mazda MPV, excluding rear self-leveling models. It is built as an OE monotube replacement to restore original ride control while adding firmer response for heavier-duty use.

Key Features

• Monotube shock design with separate hydraulic and high-pressure gas chambers
• Up to 25% more damping performance than original equipment shocks
• Engineered specifically for the Mazda MPV rear suspension
• High-pressure nitrogen gas helps deliver fade-resistant operation and quick response
• Triple chrome plated piston rod helps reduce seal wear and fluid leakage
• Supports vehicles that tow, work, or run larger tires and wheels
• Helps maintain proper operation of electronic safety systems by preserving suspension control

Product Details

The KYB Gas-a-Just line is designed for drivers who want OE-style fit and stronger damping response from a monotube shock absorber. Part number KG5198A uses an air-free hydraulic working area for control and a separate gas chamber with a floating piston for consistent performance during normal driving and immediate response when load or road conditions change. This rear shock for the Mazda MPV is a direct replacement choice for restoring suspension feel on 1989-1998 Mazda MPV models, rear, excluding rear self-leveling applications. This part cross-references Monroe Shocks & Struts (e.g., 37075) for the same application.

What It Helps Address

• Excessive rear bounce or oscillation
• Reduced steering response from worn suspension damping
• Shock fade during repeated load changes or rough-road driving
• Fluid leakage related to seal wear
• Loss of control feel on a Mazda MPV with heavier tires or towing use
