KYB KG5484 Shock Absorber - Front

KYB Gas-a-Just Front Shock for Mazda B2600

The KYB Gas-a-Just KG5484 is a monotube suspension shock absorber built to restore OE-style control on the front of 1987-1993 Mazda B2600 trucks. It uses separate hydraulic and high-pressure gas chambers for quick response, stable damping, and a more controlled ride under load.

Key Features

• Monotube design with separate gas and oil chambers for fade-resistant operation
• Up to 25% more damping performance than original equipment shocks
• Valving and components tuned for Nissan truck applications
• Higher gas pressure improves steering response and on-demand control
• Triple chrome plated piston rod helps reduce seal wear and fluid leakage
• Dust cover included for added rod protection
• Compatible with front suspension service on 1987-1993 Mazda B2600, front

Product Details

KYB Gas-a-Just shocks are designed as OE monotube replacements for vehicles that work harder than a typical commuter car. The KG5484 uses an air-free hydraulic piston area for responsiveness and a separate nitrogen gas chamber with a floating piston to maintain consistent damping during normal driving and when the suspension is asked to do more. For Mazda B2600 front suspension service, this part number KG5484 supports sharper steering feel and more controlled body motion.

This part cross-references Monroe Shocks & Struts (e.g., 37016) for the same application.

What It Helps Address

• Excessive front-end bounce after bumps or dips
• Reduced steering response and loose handling feel
• Shock fade during repeated suspension movement
• Fluid leakage caused by seal wear
• Control loss on trucks carrying heavier tires, wheels, or work loads

Installation Notes

Fits 1987-1993 Mazda B2600, front. Replace the suspension strut and coil spring assembly according to the manufacturer’s instructions.

Quality Assurance

KYB designs the Gas-a-Just line as an OE monotube replacement to help restore original suspension performance. The KG5484 is built with a high-pressure monotube layout and a chrome piston rod to support consistent damping and reduced seal wear in daily use.
