KYB KG54328 Shock Absorber - Front

KYB Gas-a-Just Front Shock Absorber

The KYB Gas-a-Just KG54328 is a monotube front shock absorber built for truck applications that need firmer control and consistent damping. It is engineered for Ford Ranger and Mazda B-Series front suspension setups where response, steering feel, and fade resistance matter.

Gas-a-Just shocks use a high-pressure monotube design with separate gas and oil chambers for quick response and stable performance during normal driving and load changes. The KG54328 is a front suspension shock absorber for 1998-2011 Ford Ranger and Mazda B2300, B2500, B3000, and B4000 applications.

Key Features

• Adds up to 25% more damping performance over original equipment shocks
• Monotube construction separates gas and oil for fade-free operation
• High-pressure nitrogen gas provides instant response and improved steering feel
• Triple chrome plated piston rod helps reduce seal wear and fluid leakage
• Valving and components are tuned for trucks, towing, and heavier wheel and tire setups
• Dust cover included
• Lower mount type: E3 (61.6 x 87 x 18); upper mount type: S1 (12 mm)

Product Details

KYB Gas-a-Just is the performance-oriented line within KYB’s shock absorber range. This design uses an air-free hydraulic working area for control and a separate high-pressure gas chamber for added force when suspension demand increases. That layout helps maintain consistent damping on rough roads, during braking, and when the vehicle is carrying added load. Part number KG54328 is a direct-fit front shock for select Ford Ranger and Mazda B-Series trucks, including 2001-2011 Ford Ranger front applications and related Mazda B2300, B2500, B3000, and B4000 front fitments. This part cross-references Monroe Shocks & Struts (e.g., 37153) for the same application.

Common Problems This Shock Can Address

• Excessive front-end bounce over bumps and uneven pavement
• Loose or delayed steering response on truck suspension setups
• Reduced damping control with towing, hauling, or larger tires and wheels
• Shock fade caused by aeration in conventional twin-tube designs
• Fluid leakage related to seal wear on worn shock absorbers
