KYB KG5446 Suspension Shock Absorber - Front

KYB Gas-a-Just Front Shock Absorber

The KYB Gas-a-just KG5446 is a front monotube shock absorber built for trucks and older light-duty applications that need firmer control than a standard twin-tube design. It uses separate gas and oil chambers for quick response, reduced fade, and more consistent damping during everyday driving and load changes.

Key Features

• Adds up to 25% more damping performance over original equipment shocks
• Monotube design separates gas and oil for fade-free operation and fast response
• High-pressure nitrogen gas helps maintain control during towing, hauling, and rough-road use
• Triple chrome plated piston rod helps reduce seal wear and fluid leakage
• Valving and components are tuned for truck applications and heavier wheel and tire setups
• Supports steering response and helps keep electronic safety systems working as designed
• Dust cover included

Product Details

Gas-a-just is KYB’s performance-oriented shock line for vehicles that work harder than a typical commuter car. The KG5446 uses a high-pressure monotube layout with an air-free hydraulic working area and a separate nitrogen gas chamber, which helps deliver consistent damping as road conditions change. For Nissan Frontier, Nissan Xterra, Nissan Pickup, Nissan D21, Nissan 720, and Chevrolet LUV front suspension service, this KYB Gas-a-just shock absorber provides direct-fit control for applications that need sharper response and stable ride behavior. This part number, KG5446, is also cross-referenced to Monroe Shocks & Struts 911530 for the same application.

Common Problems This Part Can Address

• Excessive front-end bounce after bumps or dips
• Reduced steering response during braking or lane changes
• Shock fade from heat buildup or repeated suspension movement
• Fluid leakage caused by worn seals or piston rod wear
• Loss of control on trucks with heavier tires, wheels, or added load

Installation Notes and Fitment

Fits 2000-2004 Nissan Xterra, front; replace the suspension strut and coil spring assembly according to the manufacturer’s instructions. Fits 1998-2001 Nissan Frontier, front. Fits 1995-1997 Nissan Pickup, front. Fits 1986-1994 Nissan D21, front. Fits 1981-1986 Nissan 720, front. Fits 1980-1982 Chevrolet LUV, front.

Before installation, verify compressed length 8.27 in., extended length 12.4 in., and stroke length 4.13 in. Confirm upper mount type S1 and lower mount type E2 (12x32) against the vehicle’s original suspension layout. Inspect related suspension components, and follow the vehicle manufacturer’s service procedure for proper torque and alignment checks after replacement.

Quality Assurance

KYB designs the Gas-a-just line for truck-focused damping performance and consistent operation under demanding suspension loads. The monotube construction, high-pressure gas charge, and chrome-plated rod are engineered to support long-term control and reduce the conditions that commonly lead to shock failure.
