KYB KG54315 Shock Absorber - Front

KYB Gas-a-Just Front Shock for Ram Trucks

The KYB Gas-a-just KG54315 is a front suspension shock absorber built for Dodge Ram trucks that need firmer control and quicker response than a standard twin-tube design. It uses a monotube layout with separate gas and oil chambers to reduce fade and maintain consistent damping during everyday driving and heavier-duty use.

Key Features

• Up to 25% more damping performance than original equipment shocks
• Monotube construction separates gas and oil for fade-free operation and fast response
• High-pressure nitrogen gas helps improve steering response
• Triple chrome plated piston rod helps reduce seal wear and fluid leakage
• Designed specifically for Dodge truck applications
• Dust cover included
• Front position fitment for Ram 1500 and Ram 2500 applications

Product Details

The KYB Gas-a-just line is engineered for drivers who want more control from the suspension without sacrificing normal ride quality. The KG54315 uses an air-free hydraulic working area for responsiveness and a separate high-pressure gas chamber with a floating piston to keep damping consistent as conditions change. That design helps the shock react quickly when the truck is loaded, towing, or running larger tires and wheels. This part number, KG54315, is a direct-fit front shock absorber for select 1994-2002 Dodge Ram 2500 and 1994-2001 Dodge Ram 1500 models.

This part cross-references Monroe Shocks & Struts 911104 for the same application.

Fitment

• Fits 1994-2002 Dodge Ram 2500, front. Monotube performance upgrade; excludes 8800 GVW; Gas-a-just.
• Fits 1994-2001 Dodge Ram 1500, front. Install a monotube shock absorber to enhance performance; Gas-a-just.

Common Issues This Shock Can Address

• Excessive front-end bounce over bumps and uneven pavement
• Reduced steering response during braking or lane changes
• Shock fade during repeated suspension movement
• Wear from towing, hauling, or heavier wheel and tire setups
• Fluid leakage related to seal wear on aging shocks

Installation Notes and Tips

Verify compressed length, extended length, and mount types before installation: 13.7 in. compressed length, 21.93 in. extended length, with E2 lower mount and S1 upper mount. This shock is for the front position only and should be matched to the vehicle’s exact trim and GVW notes listed in the fitment data. Inspect related suspension components, mounting points, and tire wear patterns during replacement.

Quality Assurance

KYB designs the Gas-a-just monotube platform to maintain consistent damping by separating gas and oil chambers, which helps support stable suspension performance and the operation of vehicle safety systems that rely on proper suspension behavior. The triple chrome plated piston rod is used to help reduce seal wear and support long-term durability.
