• Up to 25% more damping performance than original equipment shocks
• Triple chrome plated piston rod helps reduce seal wear and fluid leakage
• Higher gas pressure improves steering response and suspension control
• Designed specifically for Dodge truck applications

Product Details

KYB Gas-a-Just shocks are built for trucks that work, tow, or run larger tires and wheels. The KG54306 uses an air-free hydraulic piston area for control and a high-pressure nitrogen chamber for added performance on demand. That layout helps maintain fade-free operation and consistent rear suspension behavior on 1994-2002 Dodge Ram 2500 and 1994-2002 Dodge Ram 3500 models. This part number, KG54306, is a direct-fit rear suspension shock absorber for those heavy-duty Ram applications.

The Gas-a-Just line is KYB’s performance-oriented monotube shock family. It is aimed at drivers who want more damping authority than a standard twin-tube design while keeping normal ride comfort during everyday use. For shoppers comparing replacement options, KG54306 also cross-references Monroe Shocks & Struts 911192 for the same application.

What It Helps Address

• Excessive rear bounce after bumps or dips
• Reduced control when towing or carrying heavy loads
• Shock fade from heat and aeration during hard use
• Loose rear-end feel on Dodge Ram 2500 and Ram 3500 trucks
• Delayed response from worn OE-style shocks
